* Release 2.6.2mdadm-2.6.2Neil Brown2007-05-211-1/+1
|
* Add --auto-detect for in-kernel autodetect.Neil Brown2007-05-211-0/+3
| | | | This is equivalent to raidautorun that some distros provide.
* Add --export option to --detail to use key=value pairs.Kay Sievers2007-05-081-1/+2
| | | | | | | | udev likes to get information about a device as key=value pairs so it can create disk/by-id links etc. So add --export flag which causes the output of --detail to easily parsable. From: Kay Sievers <kay.sievers@novell.com>
* Don't include uclibc as part of 'everything'Neil Brown2007-02-221-0/+4
| | | | | As I cannot compile in on x86-64. Also, small dietlibc fix
* Add new mode: --incrementalNeil Brown2006-12-211-0/+33
| | | | | --incremental allows arrays to be assembled one device at a time. This is expected to be used with udev.
* Centralise code for copying uuidNeil Brown2006-12-141-0/+1
| | | | Rather than opencoding the byteswap all the time.
* Support --uuid= with --create to choose your own UUID.Neil Brown2006-12-141-2/+2
|
* Central calls to ioctl BLKGETSIZENeil Brown2006-12-141-0/+1
| | | | Instead of opencoding the same thing everywhere.
* Fix and test --update=uuidNeil Brown2006-12-141-1/+1
| | | | A number of odd bugs here, but now we have a regression test as well.
* When resync finished, report the mismatch count if there is one.Neil Brown2006-12-141-0/+2
| | | | | This doesn't get mailed out, but will appear in syslog... Maybe it should be mailed if it was a 'check' or 'repair' pass...
* --wait or -W will wait for resync activity to finish on the given devices.Neil Brown2006-12-141-0/+1
|
* Increase raid456 stripe cache size if needed to --grow the array.Neil Brown2006-12-141-0/+2
| | | | | The setting used unfortunately requires intimate knowledge of the kernel, and it not reset when the reshape finishes.
* Give useful message if raid4/5/6 cannot be started because it is not clean ↵Neil Brown2006-12-141-1/+1
| | | | and is also degraded.
* Improve allocation and use of space for bitmaps in version1 metadataNeil Brown2006-12-141-1/+2
| | | | | | | | | | Depending on the size of the array we reserve space for up to 128K of bitmap, and we use it where possible. When hot-adding to a version 1.0 we can still only use the 3K at the end though - need a sysfs interface to improve that. If a small chunksize is requested on Create, we don't auto-enlarge the reserved space - this still needs to be fixed.
* Remove some unused interfaces to the metadata handlers.Neil Brown2006-12-141-1/+0
| | | | | This stuff has never been used (at least as far as git history can see). I wonder why it was there...
* Remove partitions from components of an md arrayNeil Brown2006-10-131-0/+1
| | | | They do nothing but cause confusion.
* Allow symlink creation to be disabled from command line or mdadm.confNeil Brown2006-08-111-0/+2
|
* More consistent honoring of --configfileNeil Brown2006-06-261-9/+9
| | | | | Never use /etc/mdadm.conf if --config file is given (previously some code used one, some used the other).
* Improve ftw handling.Neil Brown2006-06-261-5/+21
| | | | | | | If not 'ftw' is available, still allow openning of devices by dev number. More recent version of uclibc support nftw, so add support to check for that.
* Yet another include file that someone doesn't like....Neil Brown2006-06-021-1/+17
| | | | | | | It seems byteswap.h isn't universally accepted, so we do it by hand... Signed-off-by: Neil Brown <neilb@suse.de>
* Allow default metadata to be specified in mdadm.confNeil Brown2006-06-021-0/+1
| | | | | | | CREATE metadata=1 in mdadm.conf will cause version-1 superblocks to be the default. Signed-off-by: Neil Brown <neilb@suse.de>
* Finally (I hope) get byteorder stuff portable.Neil Brown2006-06-021-7/+18
| | | | | | | /usr/include/endian.h and /usr/include/byteswap.h together can give us almost what we need... Signed-off-by: Neil Brown <neilb@suse.de>
* check return status of all write/fwrite functions as required by glibc 2.4Neil Brown2006-05-291-1/+1
| | | | | | | | | | | | From: Luca Berra <bluca@vodka.it> glibc 2.4 is pedantic on ignoring return values from fprintf, fwrite and write, so now we check the rval and actually do something with it. in the Grow.c case i only print a warning, since i don't think we can do anything in case we fail invalidating those superblocks (is should never happen, but then...) Signed-off-by: Neil Brown <neilb@suse.de>
* Uclibc has deprecated 'random' so use 'rand' instead.Neil Brown2006-05-291-0/+3
| | | | | | | | | | | glibc says of rand Do not use this function in applications intended to be portable when good randomness is needed. Go figure... Signed-off-by: Neil Brown <neilb@suse.de>
* add CFLAGS to mdassemble build and fix a couple of non-returning functionsNeil Brown2006-05-291-4/+2
| | | | | | | | pass CFLAGS to mdassemble build, enabling -Wall -Werror showed some issues also fixed by the patch. From: Luca Berra <bluca@vodka.it> Signed-off-by: Neil Brown <neilb@suse.de>
* Support --auto-update-homehostNeil Brown2006-05-261-0/+1
| | | | | | | | | This can be used to bootstrape homehost tagging. If no arrays are found that are tagged, we look for any array and tag it. Signed-off-by: Neil Brown <neilb@suse.de>
* When assembly arrays using incomplete detail, prefer arrays built for this host.Neil Brown2006-05-231-0/+1
| | | | | | | | i.e. if assembling with --name or --super-minor, then if we find two different arrays with the same apparent identity, and one was built for 'this' host, then prefer that one instead of giving up in disgust. Signed-off-by: Neil Brown <neilb@suse.de>
* Reorganise Assemble code somewhat.Neil Brown2006-05-231-0/+1
| | | | | | | | | | | We make sure all devices can are consistent before doing any --update This saves us from updating some but not all of an array, and then aborting. It also means we can backtrack on out decisions, which we might want to do later. Signed-off-by: Neil Brown <neilb@suse.de>
* Make sure homehost is set correctly when --update=uuidNeil Brown2006-05-231-2/+4
| | | | Signed-off-by: Neil Brown <neilb@suse.de>
* Include homehost information in --examine as appropriateNeil Brown2006-05-191-2/+2
| | | | Signed-off-by: Neil Brown <neilb@suse.de>
* Include homehost information in --detail where appropriate.Neil Brown2006-05-191-2/+2
| | | | Signed-off-by: Neil Brown <neilb@suse.de>
* Make homehost information appear in superblock.Neil Brown2006-05-191-2/+2
| | | | | | | | When an array is created, if the homehost is know, the superblock gets it, either in the uuid, (via sha1) or in the name field. Signed-off-by: Neil Brown <neilb@suse.de>
* Allow homehost to be set on command line or in config fileNeil Brown2006-05-191-0/+15

* Arrange the 'auto' setting in mdadm.conf can choose default type.Neil Brown2006-05-161-1/+1
| | | | | | | | | | | | So when you say auto=md or auto=part in mdadm.conf, it give a preference for type of array, but standard name will override. But --auto=md is more insistant. FIXME I'm not at all happy about handling of names that already exist. I don't think that should be removed if the device is active. Signed-off-by: Neil Brown <neilb@suse.de>
* When updating uuid, update the bitmap as well - external bitmapsNeil Brown2006-05-161-0/+1
| | | | Signed-off-by: Neil Brown <neilb@suse.de>
* Allow default creation info to to be stored in mdadm.confNeil Brown2006-05-151-1/+9
| | | | | | Default owner, group, mode and 'auto' flag can be given in a 'CREATE' line. Signed-off-by: Neil Brown <neilb@suse.de>
* Support 'mailfrom' line in mdadm.conf so the From: line in alert emails can ↵Neil Brown2006-05-151-0/+1
| | | | | | be explicitly set. Signed-off-by: Neil Brown <neilb@suse.de>
* Use O_DIRECT to read bitmap files.Neil Brown2006-05-151-2/+1
| | | | | | | | A pending patch to the kernel causes bitmap file updates to not go through the page cache, so O_DIRECT is needed to ensure that we read current data. Signed-off-by: Neil Brown <neilb@suse.de>
* Support 'bitmap=' in mdadm.conf for auto-assembling arrays with write-intent ↵Neil Brown2006-03-291-0/+1
| | | | | | bitmaps in separate files. Signed-off-by: Neil Brown <neilb@suse.de>
* Kill old superblocks on create.Neil Brown2006-03-281-1/+1
| | | | | | | Make sure old-version superblocks are not around to confuse anything when a new array is created. Signed-off-by: Neil Brown <neilb@suse.de>
* Create missing /dev files where needed.Neil Brown2006-03-281-1/+1
| | | | | | | Whenever we need a device file to open, if one cannot be found in /dev, create a temporary one. Signed-off-by: Neil Brown <neilb@suse.de>
* Allow resize to backup to a file.Neil Brown2006-03-271-3/+4
| | | | | | | | | | To support resizing an array without a spare, mdadm now understands --backup-file= which should point to a file for storing a backup of critical data. This can be given to --grow which will create the file, or --assemble which will restore from the file if needed. Signed-off-by: Neil Brown <neilb@suse.de>
* Remove ident arg from getinfo_super;Neil Brown2006-03-271-1/+2
| | | | | | Add a 'name' field to 'info' to compensate. Signed-off-by: Neil Brown <neilb@suse.de>

* Sort mdstat entries so that composites are well-ordered.Neil Brown2006-01-311-1/+1
| | | | | | | This means that "-Ds" lists arrays in an approprate order for assembly. Signed-off-by: Neil Brown <neilb@suse.de>
