-Subject: ANNOUNCE: mdadm 2.0 - A tool for managing Soft RAID under Linux
-
-I am (at last) please to announce the availability of
- mdadm version 2.0
-
-It is available at the usual places:
- http://www.cse.unsw.edu.au/~neilb/source/mdadm/
-and
- http://www.{countrycode}.kernel.org/pub/linux/utils/raid/mdadm/
-
-mdadm is a tool for creating, managing and monitoring
-device arrays using the "md" driver in Linux, also
-known as Software RAID arrays.
-
-Release 2.0 contains a substantial rewrite of various pieces of
-functionality, particularly the --create option. This enables support
-for a new style of superblock - the version-1 superblock.
-Version-1 can support many more than 28 devices and can be easily
-moved between hosts with different endian-ness.
-Release 2.0 also contains support for the recent bitmap-intent-logging
-which will appear in 2.6.13, and the RAID1 write-behind that will be
-available in 2.6.14 (it is currently only in -mm).
-
-This release comes with a test-suite which has been used to verify that
-mdadm-2.0 actually works in a number of common scenarios. Some of the
-tests require a bleeding-edge kernel, so don't be surprised if some fail
-on kernels prior to 2.6.14.
-
-Being a '.0' release, 2.0 should be treated with some caution.
-However I believe it is quite stable and can safely be used on
-production systems.
-
-Note that this release is "2.0", not "2.0.0". I never found a use for
-the third number with 1.X.Y, so I dropped it.
-
-
-Development of mdadm has moved from CSE@UNSW and is now sponsored by
- SUSE Labs, Novell Inc.

-mdadm is a tool for creating, managing and monitoring

-
-Release 2.1 fixes a few problems found after the release of 2.0.
-If you are using raid10 or version-1 superblocks and upgrade is
-recommended.
-
-Specifically:
- - Fix assembling of raid10 array when devices are missing.
- mdadm now correctly detects if a array is workable or not
- depending on which devices are present, and so will correctly
- handle "--assemble --force" if multiple devices have failed.
- - Report raid10 layout in --examine output.
- - Fix assembling of arrays that use the version-1 superblock and
- have spares. Previously the spares would be ignored.
- - Fix bug so that multiple drives can be re-added at once.
- - Fix problem with hot-adding a bitmap to version-1-superblock
- arrays.

-
-mdadm is a tool for creating, managing and monitoring
-device arrays using the "md" driver in Linux, also
-known as Software RAID arrays.
-
-Release 2.2 fixes a few small bugs and add as few small elements of
-functionality. Possibly the most interesting is the addition of
-'README.initramfs' and 'mkinitramfs'. Feedback on these would be
-most welcome.
-
-Changelog Entries:
- - Assorted bug fixes
- - Support write-intent-bitmaps on raid10
- - Support little-endian (Rather than hostendian) bitmaps.
- - Return correct error code from 'mdadm -S'
- - Remove extra blank line from 'mdadm -Eb' output.
- - Improve option parsing so that -a and -b do not have
- optional arguements: the arg is either required or not
- depending on context.
- - Allow scanning of devices listed in /proc/partitions even
- if they don't appear in /dev.
- - Support --assume-clean in --create mode as well as --build
- - Add support for --monitor to report to syslog: -y or --syslog.
- Thanks to Ross Vandegrift
- - --monitor now reports which device failed in a 'Fail' message
- This broke with 2.6
- - Improve chance of array starting properly after a crash.
- mdadm was insisting the event numbers were identical, but this
- isn't needed, and is a problem if the crash was while the metadata
- was being updated.
- - Support --update==uuid
- - Added README.initramfs and mkinitramfs to help people use an
- initram for starting md arrays at boot.

-
-Release 2.3 fixes an assortment of bugs including the "--assemble --scan"
-crash. It also makes mdadm better at handling very large arrays.
-Finally, it adds some functionality to support some pending kernel
-features such as raid5 reshaping.
-
-Changelog Entries:
- - Try /etc/mdadm/mdadm.conf if /etc/mdadm.conf doesn't exist.
- This provided compatability for Debian.
- - Fixed for version-1 superblock:
- report chunksize for raid6 and raid10
- make sure device size used is a multiple of chunksize
- - Fix "--assemble --scan" crash.
- - Fix completely failure to create array on ppc64
- - Fix memcmp in place of memcpy
- - A few minor improvements to online help
- - Clean up usage of 'long long' for used-size of devices, so
- that it is possible to create a raid1 of 7TB devices!
- - Make internal bitmaps work on 7TB raid1 arrays.
- - Provide error message if --examine doesn't find any superblock.
- - Report 'reshape' status in --examine - this depends on kernel
- patches that are not yet finalised.
- - Report bitmap status in --detail and --examine
- - Default to v1 superblocks instead of v0.90 if the array
- is too big for 0.90 to handle.
- - Sort the output of "mdadm --detail --scan" so that it is
- in a suitable order for assembling arrays. i.e. components come
- before an array that they are part of.
- - Print size of large reiserfs array properly went warning of
- possible confilcts.

-
-mdadm is a tool for creating, managing and monitoring
-device arrays using the "md" driver in Linux, also
-known as Software RAID arrays.
-
-Release 2.5 adds a host of minor updates and one major update.
-
-The major update involves an "Auto Assemble" function which will,
-with certainly limits, scan all available devices for anything that
-looks like an md array, and will try to assemble it.
-This code should be treated with some caution as it is very new,
-and could be revised in future, though hopefully not very much.
-
-The main problem I have always had will auto-assembly is that it
-is too easy for it to assemble thing that you don't want assembled,
-e.g. if you have moved some devices from a different computer.
-To remove this problem, arrays can now be tagged for the computer
-that is their home (homehost) and only arrays with the correct
-homehost will be auto-assembled.
-
-Feedback on the effectiveness and usefulness of this feature and it's
-documentation is encouraged.
-
-Changelog Entries:
- - Support 'mailfrom' line in mdadm.conf so the From: line in alert
- emails can be explicitly set.
- - Arrange that SparesMissing (which is similar in import to
- DegradedArray) generates an Email.
- - Assume "DEVICE partitions" if no DEVICE line is given.
- - Support new 'offset' layout for raid10.
- - When creating a bitmap file, choose a chunksize to limit number
- of bitmap chunks to 2 million. More than this can cause kmalloc
- failure.
- - New 'CREATE' line in mdadm.conf for defaults such as owner, group,
- mode and auto-flag
- - --detail checks if array has been started or not and includes that
- in report.
- - When using --update=uuid on an array with a bitmap, update the
- bitmap's uuid too.
- - Add a copy of /proc/mdstat to the mail message sent by mdadm
- --monitor.
- - New flag --no-degraded to avoid starting arrays if there are
- fewer devices available than last time the array was started.
- This is only needed with --scan, as with --scan, that behaviour
- is the default.
- - Support for 'homehost' concept. This is a fairly major update.
- It includes a configfile option and a command line option for
- specifying a homehost, records that host in the superblock,
- and reports the homehost where possible.
- - Support for Auto Assembly. "mdadm -As" will, if provided with
- the name of a homehost, try to assemble all arrays it can find
- that were created for that homehost. See man pages for more details.

-
-Release 2.5.4 is a bugfix release over 2.5.3
-
-Changelog Entries:
- - When creating devices in /dev/md/ create matching symlinks
- from /dev. e.g. /dev/md0 -> /dev/md/0.
- Allow this to be disabled in mdadm.conf or on command line.
- - Fix some endian-ness issues with version-1 superblocks (affects
- bigendian only).
- - Fix endian problem with 'bitmap' metadata
- - Allow a number (of partitions) after the 'yes' option to --auto=
- This is particularly useful in the 'create' line in mdadm.conf.
- - Remove partitions from any whole device that is made part of
- an md array. This is a work-around for annoying messages
- when the first block on some drive accidentally looks like a
- partition table.

-
-Release 2.5.5 is a bugfix release over 2.5.4.
-Hopefully the last before 2.6.
-
-Changelog Entries:
- - Don't #include linux/blkpg.h as that isn't safe. Just
- include the content literally.
- - Reduce maximum bitmap usage when working with bitmap files,
- so that a only single-page allocations are made, even on
- 64bit hosts with 4K pages.
- - Close stray fd in mdassemble so that it can assemble stacked
- devices
- - If mdassemble finds an array already assembled, it marks it
- read-write.
- - Remove error in md_open if array is already active. This isn't
- needed and gets in the ways if an array was created e.g. in
- initramfs, but device doesn't yet exist in /dev.
- - When --assemble --scan is run, if all arrays that could be found
- have already been started, don't report an error.
- - Fix a couple of bugs related to raid10 and the new 'offset' layout.
- - Improve error message when a wrong '--update' option is given.

-Subject: ANNOUNCE: mdadm 2.6 - A tool for managing Soft RAID under Linux
-
-I am pleased to announce the availability of

- http://www.cse.unsw.edu.au/~neilb/source/mdadm/

-
-mdadm is a tool for creating, managing and monitoring
-device arrays using the "md" driver in Linux, also
-known as Software RAID arrays.
-
-Release 2.6 adds assorted fixes and improvements and a new major mode.
-"Incremental Assembly" via -I or --incremental can be used to
-assemble an array one device at a time. The idea is that you get
-udev to run "mdadm -Iq devicename" on each new block device that it
-finds. Anything that is part of an array gets included in an array as
-appropriate.
-Two special notes:
- 1/ This is very new code and is probably buggy. It passes a few basic
- tests, and helped me find some kernel bugs, but it is still fresh
- and should not be considered 'stable'. Please test and provide
- feedback.
- 2/ There is a bug in the linux kernel that makes incremental assembly
- not possible in general (you cannot safely remove a drive from an array
- that has not yet been started. This is needed if an old device was
- detected first). If mdadm detects a kernel which might have the
- bug, it rejects --incremental requests.
- The bug will hopefully be fixed in 2.6.20 and this mdadm release
- contains patches for 2.6.18, 2.6.18.6 and 2.6.19. Apply the
- appropriate patch to test --incremental.
-
-Changelog Entries:
- - Fixed UUID printing in "--detail --brief" for version1 metadata.
- - --update=resync did exactly the wrong thing for version1 metadata.
- It caused a resync to not happen, rather than to happen.
- - Allow --assemble --force to mark a raid6 clean when it has two
- missing devices (which is needed else if won't assemble.
- Without this fix it would only assemble if one or zero
- missing devices.
- - Support --update=devicesize for cases where the underlying device
- can change size.
- - Default to --auto=yes so the array devices with 'standard' names
- get created automatically, as this is almost always what is wanted.
- - Give useful message if raid4/5/6 cannot be started because it is
- not clean and is also degraded.
- - Increase raid456 stripe cache size if needed to --grow the array.
- The setting used unfortunately requires intimate knowledge of the
- kernel, and it not reset when the reshape finishes.
- - Change 'Device Size' to 'Used Dev Size' because it only shows how
- much of each device is actually used, not how big they are.
- - --wait or -W will wait for resync activity to finish on the given
- devices.
- - Fix some problems with --update=uuid and add a test.
- - If two drives in a raid5 disappear at the same time, then "-Af"
- will add them both in rather than just one and forcing the array
- to 'clean'. This is slightly safer in some cases.
- - Check device is large enough before hot-add: this improves quality
- of error message.
- - Don't hold md device open for so long in --monitor mode - map_dev
- can be slow and interferes with trying to stop the array.
- - Support --uuid= with --create to choose your own UUID.
- - New major more "--incremental" for incremental assemble of arrays,
- intended for use with udev.

-Subject: ANNOUNCE: mdadm 3.0-devel1 - A tool for managing Soft RAID under Linux
-
-I am pleased to announce the availability of
- mdadm version 3.0-devel1
-
-It is available at the usual places:
- countrycode=xx.
- http://www.${countrycode}kernel.org/pub/linux/utils/raid/mdadm/
-and via git at
- git://neil.brown.name/mdadm
- http://neil.brown.name/git?p=mdadm
-
-Note that this is a "devel" release. It is not intended for
-production use yet, but rather for testing and ongoing development.
-
-The significant change which justifies the new major version number is
-that mdadm can now handle metadata updates entirely in userspace.
-This allows mdadm to support metadata formats that the kernel knows
-nothing about.
-
-Currently two such metadata formats are supported:
- - DDF - The SNIA standard format
- - Intel Matrix - The metadata used by recent Intel ICH controlers.
-
-The manual pages have not yet been updated, but here is a brief outline.
-
-Externally managed metadata introduces the concept of a 'container'.
-A container is a collection of (normally) physical devices which have
-a common set of metadata. A container is assembled as an md array, but
-is left 'inactive'.
-
-A container can contain one or more data arrays. These are composed from
-slices (partitions?) of various devices in the container.
-
-For example, a 5 devices DDF set can container a RAID1 using the first
-half of two devices, a RAID0 using the first half of the remain 3 devices,
-and a RAID5 over thte second half of all 5 devices.
-
-A container can be created with
-
- mdadm --create /dev/md0 -e ddf -n5 /dev/sd[abcde]
-
-or "-e imsm" to use the Intel Matrix Storage Manager.
-
-An array can be created within a container either by giving the
-container name and the only member:
-
- mdadm -C /dev/md1 --level raid1 -n 2 /dev/md0
-
-or by listing the component devices
-
- mdadm -C /dev/md2 --level raid0 -n 3 /dev/sd[cde]
-
-The assemble a container, it is easiest just to pass each device in turn to
-mdadm -I
-
- for i in /dev/sd[abcde]
- do mdadm -I $i
- done
-
-This will assemble the container and the components.
-
-Alternately the container can be assembled explicitly
-
- mdadm -A /dev/md0 /dev/sd[abcde]
-
-Then the components can all be assembled with
-
- mdadm -I /dev/md0
-
-For each container, mdadm will start a program called "mdmon" which will
-monitor the array and effect any metadata updates needed. The array is
-initially assembled readonly. It is up to "mdmon" to mark the metadata
-as 'dirty' and which the array to 'read-write'.
-
-The version 0.90 and 1.x metadata formats supported by previous
-versions for mdadm are still supported and the kernel still performs
-the same updates it use to. The new 'mdmon' approach is only used for
-newly introduced metadata types.
-
-Any testing and feedback will be greatly appreciated.

-
-If udev is not install, mdadm will still create devices and symlinks
-as required, and will also remove them when the array is stopped.
-
-mdadm now requires all devices which do not have a standard name (mdX
-or md_dX) to live in the directory /dev/md/. Names in this directory
-will always be created as symlinks back to the standard name in /dev.
-
-The man pages contain some information about the new externally managed
-metadata. However see below for a more condensed overview.

-
-This is a "release candidate" which means that I think it is safe
-to use and that there will be no significant change in functionality
-before release.
-
-The man pages aren't really "release candidate" yet but I will be
-working on them before the final release.
-
-The most significant changes since -devel3 relate to the names of md
-devices as they appear in /dev and /dev/md/, and in particular the names
-that are used when an array is assembled with "--incremental" or with
-"mdadm --assemble --scan" when there are no ARRAY lines in mdadm.conf.
-In these cases mdadm needs to deduce a name to use, and to try to
-avoid using a name that a different array might have a stronger claim to.
-The rules are:
- - if the array is mentioned in mdadm.conf, use the name given there.
- - if the array appear to have been created for "this host" using the
- "homehost" concept, trust the name given in the metadata
- - if the new setting "HOMEHOST <ignore>" is given (can be in mdadm.conf
- or on command line) the the name given in the metadata is not
- associated with some other array by mdadm.conf, then trust the
- name given in the metadata
- - otherwise use the name in the metadata, but in an untrusted manner.
-
-If a name is untrusted, or if the name is already in use by another
-array, then a numeric suffix like "_0", "_1" is appended to create
-a unique name for the array.
-
-That name is then used to create a device file in /dev/md/.
-
-So if all arrays needed for boot will always be listed in
-/etc/mdadm.conf, then it is appropriate to add "HOMEHOST <ignore>" to
-mdadm.conf and there is no risk of conflicting names. However if you
-want auto-assemble to assemble all arrays at boot time and you don't
-want to list them in mdadm.conf, then don't give "HOMEHOST <ignore>"
-either else there could be a risk of the wrong array being assembled
-for a given name.
-
-
-
-The following is the same introduction to 3.x as appeared in
-previous announcements.

-Any testing and feedback will be greatly appreciated.

- - Simple locking for --incremental so mdadm doesn't get confused
- when run concurrently with itself.
- - Make --incremental cope better with arrays that are being reshaped.
-
-Changes Prior to 2.6.4 release
- - Make "--create --auto=mdp" work for non-standard device names.
- - Fix restarting of a 'reshape' if it was stopped in the middle.
- - Fix a segfault when using v1 superblock.
- - Make --write-mostly effective when re-adding a device to an array.
- - Various minor fixes
-
-Changes Prior to 2.6.3 release
- - allow --write-behind to be set for --grow.
- - When adding new disk to an array, don't reserve so much bitmap
- space that the disk cannot store the required data. (Needed when
- 1.x array was created with older mdadm).
- - When adding a drive that was a little too small, we did not get
- the correct error message.
- - Make sure that if --assemble find an array in the critical region
- of a reshape, and cannot find the critical data to restart the
- reshape, it gives an error message.
- - Fix segfault with '--detail --export' and non-persistent
- superblocks.
- - Various manpage updates.
- - Improved 'raid4' support (--assemble, --monitor)
- - Option parsing fixes w.r.t -a
- - Interpret "--assemble --metadata=1" to allow any version 1.x
- metadata, and be more specific in the "metadata=" message printed
- with --examine --brief
- - Fix spare migration in --monitor.
-
-Changes Prior to 2.6.2 release
- - --fail detached and --remove faulty can be used to fail and
- remove devices that are no longer physically present.
- - --export option for --detail or present information in a format
- that can be processed by udev.
- - fix internal bitmap allocation problems with v1.1, v1.2 metadata.
- - --help now goes to stdout so you can direct it to a pager.
- - Various manpage updates.
- - Make "--grow --add" for linear arrays really work.
- - --auto-detect to trigger in-kernel autodetect.
- - Make return code for "--detail --test" more reliable. Missing
- devices as well as failed devices cause an error.
-
-Changes Prior to 2.6.1 release
- - --monitor was producing some meaningless warnings due to a bug.
- - Fix some compiler warnings.
- - Fully support --grow for raid6. If a reshape crashed during the
- critical period, mdadm wouldn't restore the Q information
- properly.
- - Update documentation for --grow.
-
-Changes Prior to 2.6 release
- - Fixed UUID printing in "--detail --brief" for version1 metadata.
- - --update=resync did exactly the wrong thing for version1 metadata.
- It caused a resync to not happen, rather than to happen.
- - Allow --assemble --force to mark a raid6 clean when it has two
- missing devices (which is needed else if won't assemble.
- Without this fix it would only assemble if one or zero
- missing devices.
- - Support --update=devicesize for cases where the underlying device
- can change size.
- - Default to --auto=yes so the array devices with 'standard' names
- get created automatically, as this is almost always what is wanted.
- - Give useful message if raid4/5/6 cannot be started because it is
- not clean and is also degraded.
- - Increase raid456 stripe cache size if needed to --grow the array.
- The setting used unfortunately requires intimate knowledge of the
- kernel, and it not reset when the reshape finishes.
- - Change 'Device Size' to 'Used Dev Size' because it only shows how
- much of each device is actually used, not how big they are.
- - --wait or -W will wait for resync activity to finish on the given
- devices.
- - Fix some problems with --update=uuid and add a test.
- - If two drives in a raid5 disappear at the same time, then "-Af"
- will add them both in rather than just one and forcing the array
- to 'clean'. This is slightly safer in some cases.
- - Check device is large enough before hot-add: this improves quality
- of error message.
- - Don't hold md device open for so long in --monitor mode - map_dev
- can be slow and interferes with trying to stop the array.
- - Support --uuid= with --create to choose your own UUID.
- - New major more "--incremental" for incremental assemble of arrays,
- intended for use with udev.
-
-Changes Prior to 2.5.6 release
- - Fix bug which meant "bitmap=xxx" in mdadm.conf was not handled
- properly.
- - Documentation updates.
- - Fix bug that caused infinite loop when doing auto-assembly,
- in certain cases where arrays couldn't be assembled.
-
-Changes Prior to 2.5.5 release
- - Don't #include linux/blkpg.h as that isn't safe. Just
- include the content literally.
- - Reduce maximum bitmap usage when working with bitmap files,
- so that a only single-page allocations are made, even on
- 64bit hosts with 4K pages.
- - Close stray fd in mdassemble so that it can assemble stacked
- devices
- - If mdassemble finds an array already assembled, it marks it
- read-write.
- - Remove error in md_open if array is already active. This isn't
- needed and gets in the ways if an array was created e.g. in
- initramfs, but device doesn't yet exist in /dev.
- - When --assemble --scan is run, if all arrays that could be found
- have already been started, don't report an error.
- - Fix a couple of bugs related to raid10 and the new 'offset' layout.
- - Improve error message when a wrong '--update' option is given.
-
-Changes Prior to 2.5.4 release
- - When creating devices in /dev/md/ create matching symlinks
- from /dev. e.g. /dev/md0 -> /dev/md/0.
- Allow this to be disabled in mdadm.conf or on command line.
- - Fix some endian-ness issues with version-1 superblocks (affects
- bigendian only).
- - Fix endian problem with 'bitmap' metadata
- - Allow a number (of partitions) after the 'yes' option to --auto=
- This is particularly useful in the 'create' line in mdadm.conf.
- - Remove partitions from any whole device that is made part of
- an md array. This is a work-around for annoying messages
- when the first block on some drive accidentally looks like a
- partition table.
-
-Changes Prior to 2.5.3 release
- - Document v0.91 superblocks in md.4
- - Make GPL explicit in man pages.
- - Fix recent breakage of starting degraded arrays.
- - Tidyup automatic name choice for v-1 arrays:
- /dev/md_d0 now becomes '0', not '_d0'.
-
-Changes Prior to 2.5.2 release
- - Fix problem with compiling with gcc-2 compilers
- - Fix compile problem of post-incrmenting a variable in a macro arg.
- - Stop map_dev from returning [0:0], as that breaks things.
- - Add 'Array Slot' line to --examine for version-1 superblocks
- to make it a bit easier to see what is happening.
- - Work around bug in --add handling for version-1 superblocks
- in 2.6.17 (and prior).
- - Make -assemble a bit more resilient to finding strange
- information in superblocks.
- - Don't claim newly added spares are InSync!! (don't know why that
- code was ever in there)
- - Work better when no 'ftw' is available, and check to see
- if current uclibc provides ftw.
- - Never use /etc/mdadm.conf if --config file is given (previously
- some code used one, some used the other).
-
-Changes Prior to 2.5.1 release
- - Various fixes for gcc warnings
- - uclibc warnings
- - Makefile improvements for static linking/intalling
- - Makefile uninstall target
- - Really fix return status of --examine
- - Typos
- - Byteorder stuff (again)
- - Don't try to create devices with --manage or --grow
- - allow default metadata (superblock) type to be specified
- in mdadm.conf
- - Get --stop to list devices stopped but honour --quiet
- - remove libssl dependency
- - Avoid some misdetection of overlapping partitions
- - Fix memory leak in --monitor mode
-
-Changes Prior to 2.5 release
- - Support 'mailfrom' line in mdadm.conf so the From: line in alert
- emails can be explicitly set.
- - Arrange that SparesMissing (which is similar in import to
- DegradedArray) generates an Email.
- - Assume "DEVICE partitions" if no DEVICE line is given.
- - Support new 'offset' layout for raid10.
- - When creating a bitmap file, choose a chunksize to limit number
- of bitmap chunks to 2 million. More than this can cause kmalloc
- failure.
- - New 'CREATE' line in mdadm.conf for defaults such as owner, group,
- mode and auto-flag
- - --detail checks if array has been started or not and includes that
- in report.
- - When using --update=uuid on an array with a bitmap, update the
- bitmap's uuid too.
- - Add a copy of /proc/mdstat to the mail message sent by mdadm
- --monitor.
- - New flag --no-degraded to avoid starting arrays if there are
- fewer devices available than last time the array was started.
- This is only needed with --scan, as with --scan, that behaviour
- is the default.
- - Support for 'homehost' concept. This is a fairly major update.
- It includes a configfile option and a command line option for
- specifying a homehost, records that host in the superblock,
- and reports the homehost where possible.
- - Support for Auto Assembly. "mdadm -As" will, if provided with
- the name of a homehost, try to assemble all arrays it can find
- that were created for that homehost. See man pages for more details.
-
-Changes Prior to 2.4.1 release
- - Honour --write-mostly when adding to an array without persistent
- superblocks.
- - Fix alignment problem in version-1 superblocks.
- NOTE: This is an incompatable change affecting raid5 reshape.
- If you want to reshape a raid5 using version-1 superblocks,
- use 2.6.17-rc2 or later, and mdadm-2.4.1 or later.
-
-Changes Prior to 2.4 release
- - Rewrite 'reshape' support including performing a backup
- of the critical region for a raid5 growth, and restoring that
- backup after a crash.
- - Put a 'canary' at each end of the backup so a corruption
- can be more easily detected.
- - Remove useless 'ident' arguement from ->getinfo_super method.
- - Support --backup-file for backing-up critical section during
- growth.
- - Erase old superblocks (of different versions) when creating new
- array.
- - Allow --monitor to work with arrays with >28 devices
- - Report reshape information in --detail
- - Handle symlinks in /dev better
- - Fix mess in --detail output which a device is missing.
- - Manpage tidyup
- - Support 'bitmap=' in mdadm.conf for auto-assembling arrays with
- write-intent bitmaps in separate files.
- - Updates to md.4 man page including section on RESTRIPING and SYSFS
-
-Changes Prior to 2.3.1 release
- - Fixed -O2 compile so I could make and RPM.
- - Type cast number to be printed %llu so it compiles on 64bit
- machines. (Thanks Luca).
- - Stop using asm/byteorder.h - to make Redhat happy :-(
- - Require bitmap files to have a '/' in their name.
- - Error-check a few syscalls - code from SuSE package.
-
-Changes Prior to 2.3 release
- - Try /etc/mdadm/mdadm.conf if /etc/mdadm.conf doesn't exist.
- This provided compatability for Debian.
- - Fixed for version-1 superblock:
- report chunksize for raid6 and raid10
- make sure device size used is a multiple of chunksize
- - Fix "--assemble --scan" crash.
- - Fix completely failure to create array on ppc64
- - Fix memcmp in place of memcpy
- - A few minor improvements to online help
- - Clean up usage of 'long long' for used-size of devices, so
- that it is possible to create a raid1 of 7TB devices!
- - Make internal bitmaps work on 7TB raid1 arrays.
- - Provide error message if --examine doesn't find any superblock.
- - Report 'reshape' status in --examine - this depends on kernel
- patches that are not yet finalised.
- - Report bitmap status in --detail and --examine
- - Default to v1 superblocks instead of v0.90 if the array
- is too big for 0.90 to handle.
- - Sort the output of "mdadm --detail --scan" so that it is
- in a suitable order for assembling arrays. i.e. components come
- before an array that they are part of.
- - Print size of large reiserfs array properly went warning of
- possible confilcts.
-
-Changes Prior to 2.2 release
- - Assorted bug fixes
- - Support write-intent-bitmaps on raid10
- - Support little-endian (Rather than hostendian) bitmaps.
- - Return correct error code from 'mdadm -S'
- - Remove extra blank line from 'mdadm -Eb' output.
- - Improve option parsing so that -a and -b do not have
- optional arguements: the arg is either required or not
- depending on context.
- - Allow scanning of devices listed in /proc/partitions even
- if they don't appear in /dev.
- - Support --assume-clean in --create mode as well as --build
- - Add support for --monitor to report to syslog: -y or --syslog.
- Thanks to Ross Vandegrift
- - --monitor now reports which device failed in a 'Fail' message
- This broke with 2.6
- - Improve chance of array starting properly after a crash.
- mdadm was insisting the event numbers were identical, but this
- isn't needed, and is a problem if the crash was while the metadata
- was being updated.
- - Support --update==uuid
- - Added README.initramfs and mkinitramfs to help people use an
- initram for starting md arrays at boot.
-
-Changes Prior to 2.1 release
- - Fix assembling of raid10 array when devices are missing.
- mdadm now correctly detects if a array is workable or not
- depending on which devices are present, and so will correctly
- handle "--assemble --force" if multiple devices have failed.
- - Report raid10 layout in --examine output.
- - Fix assembling of arrays that use the version-1 superblock and
- have spares. Previously the spares would be ignored.
- - Fix bug so that multiple drives can be re-added at once.
- - Fix problem with hot-adding a bitmap to version-1-superblock
- arrays.
-
-Changes Prior to 2.0
- - Support assembling from byte-swapped superblocks
- metadata type "0.swap" and --update=byteorder
- - write-mostly and write-behind support for raid1.
- - Support --name= and 'name=' config entry for identifying
- arrays be name.
- - RAID10 in man pages.
- - Lot of minor manpage updates
-
-Changes Prior to 2.0-devel-3 release
- - Assorted fixes for multiple bugs...
- - Add test suite
-
-Changes Prior to 1.12.0 release
- Several of these are backported from the Debian package
- - Don't use 'lstat' to check for blockdevices, use stat.
- - Document --size=max option for --grow
- - Document SparesMissing event and DeviceDisappeared/WrongLevel
- - --stop --scan repeatly cycles until no more progress can be made
- so that stack devices are stopped properly
- - Minor type rationalisation for ident->uuid - now always 'int[]'
- - Fix type in online help for --grow (was -F, now -G)
- - Allow --auto command line option to set default auto=
- value when running "--assemble --scan". Previously
- --auto was ignored if --scan was given
- - Fix a few type casts
- - Fix parsing of /dev/md/N in is_standard
- - Fix rounding errors in human_size()
- - Fix silly example in mdadm.conf-examples
- - When finding a /dev name for a device, prefer shorter names
- - Suppress listing of devices= in --brief output of -D or -E,
- unless -v is given (-vv gives the old behaviour with -Dsv).
- This is because the device list can change and so is not a
- stable aspect of the array
- - Allow --force with --grow so '-Gfn1' works (on raid1)
- - Replace sprintf calls with snprintf (to quiet diet-libc)
- - Add man page for mdassemble
- - Fix compilation with tinyc
-
-Changes Prior to 1.11.0 release
- - Fix embarassing bug which causes --add to always fail.
-
-Changes Prior to 1.10.0 release
- - Fix bug with --config=partitions
- - Open sub-devices with O_EXCL to detect if already in use
- - Make sure superblock updates are flushed directly to disk.
-
-Changes Prior to 2.0-devel-1 release
- - Support for version-1 superblock. See --metadata option.
- - Support for bitmap based intent logging.
- - Minor fixes.
-
-Changes Prior to 1.9.0 release
- - Fix rpm build problem (stray %)
- - Minor manpage updates
- - Change "dirty" status to "active" as it was confusing people.
- - --assemble --auto recognises 'standard' name and insists on using
- the appropriate major/minor number for them.
- - Remove underscore from partition names, so partitions of
- "foo" are "foo1", "foo2" etc (unchanged) and partitions of
- "f00" are "f00p1", "f00p2" etc rather than "f00_p1"...
- - Use "major", "minor", "makedev" macros instead of
- "MAJOR", "MINOR", "MKDEV" so that large device numbers work
- on 2.6 (providing you have glibc 2.3.3 or later).
- - Add some missing closes of open file descriptors.
- - Reread /proc/partition for every array assembled when using
- it to find devices, rather than only once.
- - Make "mdadm -Ss" stop stacked devices properly, by reversing the
- order in which arrays are stopped.
- - Improve some error messages.
- - Allow device name to appear before first option, so e.g.
- mdadm /dev/md0 -A /dev/sd[ab]
- works.
- - Assume '-Q' if just a device is given, rather than being silent.
- - Change "dirty" status to "active" as it was confusing people.
-

- faults. (Not in kernel.org yet at 1Nov2004)
- - Support raid0/linear on devices > 2 Terabytes
- - Make sure raid6 resyncs when created with one missing device
-
-Changes Prior to 1.7.0 release
- - Support "--grow --add" to add a device to a linear array, if the
- kernel supports it. Not documented yet.
- - Restore support for uclibc which was broken recently.
- - Several improvements to the output of --detail, including
- reporting "resyncing" or "recovering" in the state.
- - Close filedescriptor at end of --detail (exit would have closed it
- anyway, so this isn't abig deal).
- - Report "Sync checkpoint" in --examine output if appropriate.
- - Add --update=resync for --assemble mode to for a resync when the
- array is assembled.
- - Add support for "raid10", which is under development in 2.6.
- Not documented yet.
- - --monitor now reads spare-group and spares info from config file
- even when names of arrays to scan are given on the command line
-
-Changes Prior to 1.6.0 release
- - Device name given in -Eb is determined by examining /dev rather
- than assuming /dev/md%d
- - Fix bug in --monitor where an array could be held open an so
- could not be stopped without killing mdadm.
- - Add --grow mode. Currently only --size and --raid-disks can be
- changed. Both require kernel support which, at the time of
- writing, is not in a release kernel yet.
- - Don't print out "errors" or "no-errors" in -D and -E, as the bit
- is never set or used.
- - Use md event notification in 2.6.??? to make --monitor mode
- respond instantly to events.
- - Add --auto= option and auto= configfile entry to tell mdadm to
- create device files as needed. This is particularly useful
- with partitioned arrays where the major device number can change.
- - When generating --brief listing, if the standard name doesn't
- exist, search /dev for one rather than using a temp name.
- - Allow --build to build raid1 and multipath arrays.
- - Add "--assume-clean" for Create and Build, particularly for raid1
- Note: this is dangerous. Only use it if you are certain.
- - Fix bug so that Rebuild status monitoring works again.
- - Add "degraded" and "recovering" options to the "Status:"
- entry for --detail
-
-Changes Prior to 1.5.0 release
- - new commands "mdassemble" which is a stripped-down equivalent of
- "mdadm -As", that can be compiled with dietlibc.
- Thanks to Luca Berra <bluca@comedia.it>.
- It can be using in an initramfs or initrd.
- - Fix compiling error with BLKGETSIZE64 and some signed/unsigned
- comparison warnings.
- - Add Rebuild Status (% complete) to --detail output.
- - Support "--monitor --test" which will generate a test alert
- for each array once, to test notification paths.
- - Generate RebuildFinished event when rebuild finishes.
- - Support for raid6 as found in 2.6.2 - thanks to
- H. Peter Anvin <hpa@zytor.com>
- - Support partitioned md arrays with a different major number and
- naming scheme (md_dX in /proc/mdstat, /dev/md/dXpY in /dev).
-
-Changes Prior to 1.4.0 release
- - Document fact that creating a raid5 array really creates a
- degraded array with a spare.
- - Add "spares=" tag to config file and generate it wit --detail and
- --examine
- - Add "SparesMissing" event when --monitor first sees an array and
- it doesn't have the enough spare devices.
- - Add --update=summaries for --assemble to update summary
- information in superblock, and correct other inconsistancies in
- the superblock.
- - Add --test option to --detail to set a meaningful exit status.
-
-Changes Prior to 1.3.0 release
- - Make 'size' and unsigned long in Create to allow creation of
- larger arrays.
- - Explicitly flag spare devices as 'spare' in --detail and --examine
- output. Previously they simply had no flags lists.
- - Make MailCmd (for monitor) configurable in Makefile, and default
- to "/usr/sbin/sendmail -t". Also split out the warning related
- flags into CWFLAGS for easier build configurability.
- - Minor bugfix in Manage code.
- - --monitor now notices and reports degraded arrays at startup using
- "DegradedArray" event, and also has a --oneshot option to only
- report DegradedArrays, and then exit.
- - Small man-page clarification w.r.t. raid levels and raid4 in
- particular.
- - Disallow creation of arrays with only one device as this is
- probably a mistake. --force will override this check.
- - Correct some misleading documentation in the "mdadm --create --help"
- message.
- - Ignore chunksize if raid1 or multipath.
- - Explicit statement in man page that raid-disks cannot be changed
- after array is created.
- - Improve message when attempting to start an array with
- insufficient devices. Instead of required the array to be full,
- we only require it has as many active devices as last time.
-
-Changes Prior to 1.2.0 release
- - Fix bug where --daemonise required an argument.
- - In --assemble --verbose, print appropriate message if device is
- not in devices= list
- - Updated mdadm.conf.5 to reflect fact that device= takes wildcards
- - Typos: componenet -> component
- - Reduce size of "--help" message put excess into "--help-options"
- - Fix bug introduced when MD_SB_DISKS dependancy removed, and which
- caused spares not be assembled properly.
- - Print appropriate message if --monitor --scan decides not to
- monitor anything.
-Changes Prior to 1.1.0 release
- - add --deamonise flag for --monitor - forks and prints pid to stdout
- - Fix bug so we REALLY clear dirty flag with -Af
- - -Db now prints a 'devices=' word for each array.
- - "mdadm -A /dev/md0" will get info from configfile, even without scan
- - When assembling multipath arrays, ignore devices which are flagged
- as having errors.
- - take --super-minor=dev to mean "use the minor number of the mddev
- being assembled.
- - take --config=none to mean "completely ignore config file"
- - Make --monitor require --scan or a device list.
-Changes Prior to 1.0.9 release
- - Documentation updates including kernel parameters documented
- in md.4
- - --assemble --force for raid4/5 will mark clean, needed for 2.5
- - --detail prints out the events counter as well
- - flush device before reading superblock to be sure to get
- current data
- - added mdadm.static target to makefile for static linking
- - --monitor was ignoring /dev/md0 due to off-by-one error
- - Fix assorted typos
- - Fix printing of Gibibytes - calc was wrong.
- - Fix printing of Array Size in --detail when very big.
- - --monitor no longer tries to work for raid0 or linear as these
- have nothing to be monitored.
- - The word 'partitions' on a DEVICE line will cause all partitions
- listed in /proc/partitions to be considered
- - If the config file is called 'partitions' then it will be treated
- as though it contained exactly 'device partitions' so e.g.
- mdadm -Ebsc partitions
- will find all raid partitions easily.
- - successfully assemble multipath devices by ignoring raid_disk
- value from superblock (it is always the same).
- - --assemble not tied to MD_SB_DISKS limit quite so much
- - Support compiling with tcc
- - Support compiling with uclibc - just skip scan of /dev
- - Add --update= option for Assemble mode. Either sparc2.2
- or super-minor updates are possible. See mdadm.8
-
-Changes Prior to 1.0.1 release
- - Round off MB/GiB etc values instead of round down.
- - Add --sparc2.2 option to examine to shift superblock around
- and --sparc2.2update to rewrite the superblock
- - Fix assorted typos in online help
-
-Changes Prior to 1.0.0 release
- - Allow --config with Misc mode (for --examine --scan)
- - Add $(CXFLAGS) to end of CFLAGS in makefile
- - When making an N disk raid5 array, the Nth drive
- is moved to the end of the array as a spare rather than
- being shifted up one place. This means that when the
- kernel builds onto the last spare and inserts it,
- the devices will be in the expected order.
- - Man page improvements
-Changes Prior to 0.8.2 release
- - Correct spelling of persist[ae]nce/persist[ae]nt.
- - Change "disk" to "device" in options and config file
- - convert array size to "long long" *before* shift-left in -D and -Q
-
-Changes Prior to 0.8.1 release
- - Add "INSTALL" file.
- - Fix some "i" variables that were not being set properly
- - Initialise minsize and maxsize so that compilers don't complain.
- - Tidy up Makefile and mdadm.spec installations
- - Add "multipath" to documentation of valid levels
-
-Changes Prior to 0.8 release
- - Fix another bug in Assemble.c due to confusing 'i' with 'j'
- - Minimal, untested, support for multipath
- - re-write of argument parsing to have more coherent modes,
- - add --query,-Q option
- - Update mdadm.8 to reflect arg processing change and --query
- - Change "long" to "unsigned long" for device sizes
- - Handle "mailaddr" and "program" lines in config file for follow/scan mode.
- - --follow --scan will exit if no program or mail found
- - Add MAILADDR and PROGRAM to mdadm.conf-example
- - Spell check man pages
- - consistently use "component devices" instead of "subdevices"
- - Make -Wall -Werror really work and fix lots of errors.
- - --detail and --stop can have --scan which chooses devices from /proc/mdstat
- - --monitor detects 20% changes in resync, failed spares,
- disappearing arrays,
- - --monitor --scan will automatically add any devices found in /proc/mdstat
- - --monitor will move spares between arrays with same spare-group if necessary
- - Documentation for Monitor Mode
- - --query notes if the array containing the given device is active or not
- - Finished md.4 man page.
-
-Changes Prior to 0.7.2 release
- - mdadm.spec updates and ifdef BLKGETSIZE64 from Luca Berra -- bluca@comedia.it
- - more mdadm.spec updates from Gregory Leblanc <gleblanc@linuxweasel.com>
- - make directory for mdadm.conf configurable in Makefile
- - Finished mdadm.conf.5. Removed details of conf file from
- mdadm.8 leaving a reference to mdadm.conf.5.
- - Fix bug in Assemble.c, thanks to Junaid Rizvi <domdev@sat.net.pk>
- - Get --assemble --force to make sure old major/minor numbers are
- consistant, as md.c worries about this :-(
-
-
-Changes Prior to 0.7.1 release
- - update mdadm.spec
- - use BLKGETSIZE64 if available for array size
- - give human readable as GiB/MiB and GB and MB, with 2 decimal point precision
- - Only warn about size variation for raid1/4/5.
- - Started md.4 man page
- - Started mdadm.conf.5 man page
-
-Changes Prior to 0.7 release
-
- - Fix makefile to install binary at /sbin and not /sbin/sbin
- Also install man page.
- - Add --zero-superblock based on --destroywithextremeprejudice
- from Dale Stephenson <steph@snapserver.com>
- - change name to mdadm. It is palandromic, and much nicer to pronouce.
-
-Changes Prior to 0.6 release
-
- - Remove the limit on the number of device names that can be
- given on the command line.
- - Fix bug in --assemble --force where it would only update a
- single superblock.
- - Fix bogus printing of big numbers not being block devices
- when given names of devices that don't exist.
- - When --assemble --force, consider superblocks with an event
- count that is 1 behind as out-of-date. Normally they are
- considered up-to-date (as the kernel assumes this too).
- - When marking drives as not-failed in the superblock,
- we also mark them as ACTIVE and SYNC.
- - Don't start arrays for which not all drives are available unless:
- --scan which implies that all drives were found automatically
- --run which means the user knows what they want
- --force which means that we are fixing something broken
- - Make sure all device numbers passed as 3rd arg of ioctl
- are passed as unsigned lock, so that it works on SPARC
- - If HOT_ADD_DISK failes for -a, then only try ADD_NEW_DISK
- if we cannot read from the array, i.e. if the array is
- not started yet.
- - man page update
- - Taught Examine to handle --scan. It examines all devices listed
- on DEVICE lines in the config file.
- - Added --brief (-b) flag for Examine and Detail to print out
- and mdctl.conf compatible description with uuid=, level=,
- disks= and - for Examine - devices=
- --examine --brief collects all devices the make the one array and
- list them as one entry.
- - Added level= and disks= options to ARRAY lines in config files
- so --brief output could be used as-is.
- - Make parity style ({left,right}-{,a}symmetric) consistantly use -,
- never _.
- - Add "Array Size" to --detail output
- - Change "Size" to "Device Size" and exclude from Detail of arrays
- that do not have a consistent device size.
- - Add Human readable MiB or GiB value on size lines of Detail and Examine
- - --assemble --scan doesn't complain about active drives
- - require number of spares given in -x to be listed.
- - Made --build actually work.
-Changes Prior to 0.5 release
-
- --assemble:
- spare drives are handled properly.
-
- --force can be used to recover from 2-drive failures on RAID5
- If you belive that /dev/hda1 /dev/hdb1 /dev/hdc1 /dev/hdd1 should
- make a raid5 array, but it has experienced multiple failures and
- wont start, then
-
- mdctl --assemble --force /dev/md0 /dev/hd[abcd]1
-
- Should update the superblock on the newest failed drive and
- restart the array in degraded mode. You should then remove the
- remaining failed drive and re-add it (if you are happy that it
- might work).
-
- Ofcourse whenever you have a 2-drive failure, you have a risk
- of corruption in data that hasn't be changed for a long time. So
- this doesn't give you your array back all nice and happy, but it
- does allow you to recover data that might not be corrupt.
-
- More flexibility in identifying a RAID array in the mdctl.conf
- e.g.
- array /dev/md4 super-minor=4
-
- assembles /dev/md4 from all devices found that have a raid
- superblock that says the minor number of the array is 4.
- If the blocks with the right minor number do not all have the
- same UUID, an error is flags and no assembly happens.
-
- array /dev/md3 devices=/dev/hd[abc]2
-
- Assembles /dev/md3 drom /dev/hda2 /dev/hdb2 and/dev/hdc2. All
- devices must exist and have raid superblock with the same uuid.
-
- If two identity specifiers are used, only devices that match all
- of them are considered, so
-
- array /dev/md2 devices=/dev/hd?2 super-minor=2
-
- will assemble /dev/md2 using all /dev/hd?2 devices which have a
- raid superblock with minor number 2.
-
- --create:
- When listing devices for --create, the word "missing" can be
- used to indicate that the respective slot does not have a
- working drive currently. This is similar to the "failed-disk"
- directive in mkraid/raidtab.
- e.g.
- mdctl --create --level=5 -raid-disks=4 --spare-disks=2
- /dev/md0 /dev/sda /dev/sdb missing /dev/sdc /dev/sdd /dev/sde
-
- will create a raid5 array with the third slot empty, and two
- spares.
-
- By default, raid5 arrays are created with the last slot empty
- and drive listed for the last slot added as a spare. If a
- "missing" slot is given, or if --force is given, then --create
- does exactly what you ask and doesn't try to be clever.
-
-
- --follow / --monitor:
-
- This is a new mode. I couldn't stop my self from picking a name
- starting with F (as current modes start A,B,C,D,E) but I
- relented and provided an alternate name that is somewhat more
- meaningful.
-
- In this mode, mdctl does not exit, but runs continuously and
- periodically polls all the md devices to see if they have had
- any interested state change.
- The changes that it currently notices are:
- Fail - an active disc fails
- FailSpare - a spare, that was presumably being build, fails
- ActiveSpare - a spare becomes active, presumably after a rebuild.
-
- Options:
- --mail mailaddress - send Email on any Fail* event
- --program program - run the program on any event.
- Args are: eventname mddevice subdevice(if-known)
- --delay seconds - change from the default 60second pause
- between polls.
-
- I plan to add functionality to this mode to allow sharing of
- spare drives. If an array is marks "spare-group=fred", and it
- has a failed drive and no spares, and if some other array is
- also "spare-group=fred" and it has no failed drives, but does
- have a spare drive that is big enough, the spare will be moved
- to the first array.
-
- I also have the idea of adding a --grow mode which will re-organise
- the data on an N disk raid0/4/5 array to be on an N+M disk array.
- I have no concrete plans for this though.
-
- I got rid of the "v" in the archive file name, and include the
- version number in the directory created by the archive.
-
- There is now a man page and mdctl.spec (for rpm) thanks to
- Danilo Godec <danci@agenda.si>.
-
- Ofcourse, the man page is now out of date and despite being based on
- the --help output, is not wholy correct. After I get --follow
- working properly, I plan to revise the various documentation and/or
- the code to make sure the two match.
+Please see git logs for detailed change log.
+This file just contains highlight.
+
+Changed Prior to release 3.0
+ - Support for externally managed metadata, specifically DDF and IMSM.
+ - Depend on udev to create entries in /dev, rather than creating them
+ ourselves.
+ - remove --auto-update-home-hosts
+ - new config file line "auto"
+ - new "<ignore>" and "any" options for "homehost"
+ - numerous bug fixes and minor enhancements.
