| | | | The user of dup_super broke it.
* Recent change broken handling of metadata-less arrays.Neil Brown2008-05-152-3/+5
| | | | | In particular, failing a device would give a silly error message.

| | | | | If the first device we look at has no superblock, there is no 'st' to free, so don't free it.

* Simplistig locking for --incremental.Bill Nottingham2008-05-051-1/+14
| | | | | | | | | | | | | | | | | | From: Bill Nottingham <notting@redhat.com> mdadm --incremental doesn't really do any locking. If you get multiple events in parallel for the same device (that has not yet started), they will all go down the path to create the array. One will succeed, the rest will have SET_ARRAY_INFO die with -EBUSY (md: array mdX already has disks!) and will exit without adding the disk. Original bug report is: https://bugzilla.redhat.com/show_bug.cgi?id=433932 This is solved by adding very very rudimentary locking. Incremental() now opens the device with O_EXCL to ensure only one invocation is frobbing the array at once. A simple loop just tries to open 5 times a second for 5 seconds. If the array stays locked that long, you probably have bigger issues.
* Create /dev/md if needed and it doesn't exist.Bill Nottingham2008-05-051-0/+14
| | | | From: Bill Nottingham <notting@redhat.com>
* Fix RAID acronym in man page.Neil Brown2008-05-051-2/+2
| | | | The 'D' in 'RAID' stands for 'DISKS' even it md supports other 'devices'.
* Add a .gitignore file.Neil Brown2008-04-291-0/+5
|
* Use .\" instead of '''Neil Brown2008-04-291-66/+66
| | | | Debian bug 477273
* diff -ru mdadm-2.6.4-orig/Query.c mdadm-2.6.4/Query.cNeil Brown2008-04-292-0/+6

* Fix possible bug with bitmap space allocation with v1.0 metadataNeil Brown2008-04-294-13/+15
| | | | | When adding a device to an array, make sure we don't reserve so much space for the bitmap that there isn't room for the data.
* Small improvements to --incremental for arrays that are in the middle of reshapeNeil Brown2008-04-281-1/+2
| | | | | | There is still a problem: If array is partially assembled and started read-only, the last device doesn't get added properly. Probably a kernel problem.
* Allow creation of a RAID6 with a single missing device.Neil Brown2008-04-282-2/+19
| | | | | | | | This did not work before as we couldn't mark it clean as there would be some parity blocks out of sync, and raid6 will not assemble a dirty degraded array. So make such arrays doubly degraded (the last device becomes a spare) and clean.
* Updates some URLs in the man page.Neil Brown2008-04-282-4/+9
| | | | Particularly, add the wiki on osdl.org
* Print 'Events' more sensibly.Neil Brown2008-04-282-1/+5
| | | | Instead of MSW.LSW, just print it as a 64bit number.
* Fix problems with array.size overflowing on large arrays.Neil Brown2008-04-283-3/+14
| | | | | | | | | | | array.size is 32bits and counts K. So for arrays with more than 4Terrabytes, it can overflow. The correct number can be read from sysfs, but there are still a few places that use array.size and risk truncation. What is worse. they compare a number of kilobytes with a number of sectors !! So use get_component_size() to read the sysfs information, and be more consistent about units.
* Fix for segfault when reading /proc/mdstatNeil Brown2008-04-284-0/+19
| | | | | | | | | Some kernel versions don't put a space between 'active' and '(auto-read-only)' in /proc/mdstat. This causes a parsing problem leaving 'level' set to NULL which causes a crash. So synthesise a space there if it is missing, and check for 'level' to be NULL and don't de-ref if it is.
* Use sysfs info for metadata version info in Detail and elsewhere.Neil Brown2007-12-143-13/+38
|
* Replace sysarray with mdinfoNeil Brown2007-12-146-63/+61
| | | | | Sure, mdinfo is bigger, but having a uniform structure for lots of things will make life easier.
* Use 'mdinfo' instead of special 'sysdev' structure.Neil Brown2007-12-145-88/+86
| | | | | there is needless duplicatiion between mdinfo and sysdev, so discard the latter.
* Some tidy up of 'devices' in assemble.Neil Brown2007-12-141-56/+56
| | | | | use "mdinfo" in the devices list rather than just copying ad-hoc fields in.
* Don't record oldmajor/oldminor any more during assemble.Neil Brown2007-12-141-3/+0
| | | | We don't use the information at all (any longer).
* Find super from fd on an array.Neil Brown2007-12-145-21/+53
| | | | | We used to use the major/minor numbers, but that isn't sufficient any more, so pass the fd, and possibly check 'text' version.
* Drop the superblock arg from all metadata methods.Neil Brown2007-12-1414-325/+330
| | | | It is now in the 'supertype'
* Fix compare_super to take supertype instead of a superblock.Neil Brown2007-12-145-13/+19
| | | | | As this function takes 2 superblocks, the change is a bit more subtle, so is done separately.
* Add 'supertype' arg to almost all metadata methods.Neil Brown2007-12-1413-117/+128
| | | | The 'superblock' will be moved into this structure soon.
* Allow metadata handlers to free their own superblock.Neil Brown2007-12-1411-54/+64
| | | | | | As the metadata handler allocates the superblock, it should free it too. DDF will have a more complex 'superblock' which needs more complex freeing.
* Make sure sysfs_read never succeeds for a non-MD device.Neil Brown2007-12-141-1/+4
| | | | ... just in case.
* Remove spaces/tabs from ends of lines.Neil Brown2007-12-1423-125/+120

* A recent patch broke --create --level=faulty - fix it.Neil Brown2007-11-291-0/+1

* Remove partitions from a device before adding it to an array.Neil Brown2007-10-191-1/+1
| | | | | The 'remove_partitions' call is in the wrong place and applying to the wrong file.
* Add some extra consistency checks based on level.Neil Brown2007-10-172-6/+21
| | | | Also use LEVEL_LINEAR, LEVEL_MULTIPATH in place of -1 or -4 in a few places.
* Clarify the avail/used devices sizes with version1 superblock.Neil Brown2007-10-171-2/+2
| | | | | Not all of the device may be available. Of that, not all may be used (if devices are of different sizes).
* Make sure --auto=mdp is honoured properlyNeil Brown2007-10-171-0/+1
| | | | | This would only create partitioned devices if the device name was a 'standard' name. This this patch, any name will work.
