| * vol_id was removed by the udev upstream maintainer in May 2009.Marco d'Itri2009-10-291-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | One should use /sbin/blkid -o udev -p ... (from util-linux >> 2.16) instead of vol_id --export ...

| * Remove bogus warnings from man page.NeilBrown2009-10-291-6/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | LANG=C man --warnings -l mdadm.8 > /dev/null complains that '.XX' is an invalid macro. This is not correct. The sequence .ig XX anything can go here .XX is correct and is ignored (see 'info groff' and the 'ig' index entry). However the same can be achieved with .ig anything can go there .. and this produces no warnings, so use that instead. Signed-off-by: NeilBrown <neilb@suse.de>
* | Assemble: fix testing of 'verbose' flag.NeilBrown2009-11-191-2/+2
| | | | | | | | | | | | | | The 'verbose' flag can be negative, meaning 'quiet'. So never check for != 0. Signed-off-by: NeilBrown <neilb@suse.de>
* | Create: warn when creating a raid1 using default metadata.NeilBrown2009-11-191-0/+11
| | | | | | | | | | | | | | | | As a some/most bootloaders don't understand md metadata, it might be difficult to boot off an array with the default 1.0 metadata. So if this is used for a RAID1, ask for confirmation. Signed-Off-By: NeilBrown <neilb@suse.de>
* | Don't silently map --re-add to --addNeilBrown2009-11-171-0/+6
| | | | | | | | | | | | | | | | | | As --add can destroy important data on a disk, and --re-add is not suppose to, it is wrong to silently try --add if --re-add fails. So print a message and abort instead. Signed-off-by: NeilBrown <neilb@suse.de>
* | Improve error messages when metadata handler does not support request.NeilBrown2009-11-175-10/+33
| | | | | | | | | | | | | | | | | | ->validate_geometry is called to validate overall parameters, and to validate each individual device. If it ever fails, it needs to report the reason, as common code cannot possible know. Signed-off-by: NeilBrown <neilb@suse.de>
* | Set default bitmap-chunksize for internal bitmaps to at least 64MegNeilBrown2009-11-1713-17/+27
| | | | | | | | | | | | | | | | | | A small bitmap-chunksize hurts performance without helping resync speed much - particularly on internal bitmaps. So set the default to at least 64Meg. Signed-off-by: NeilBrown <neilb@suse.de>
* | Grow: various fixes to recent breakages.NeilBrown2009-11-171-5/+8
| | | | | | | | | | | | | | - I forgot to write the send backup-super-block on spares. - I wasn't adding the data_offset to an offset Signed-off-by: NeilBrown <neilb@suse.de>
* | Change default metadata from 0.90 to 1.1NeilBrown2009-11-1735-97/+106
| | | | | | | | | | | | | | | | | | 1.1 is more flexible in a number of ways and is safer. 0.90 is still fully supported. 1.0 should possibly be used for RAID1 arrays that you want to boot off, depending on your boot loader. Signed-off-by: NeilBrown <neilb@suse.de>
* | Increase default chunk size to 512KNeilBrown2009-11-1720-41/+51
| | | | | | | | | | | | | | | | | | | | | | This seems more appropriate for current (and recent) model drives than 64K. 64K is still the default for '--build' as changing that could corrupt data. 64K is also the default rounding for 'linear' on kernels older than 2.6.16. Signed-off-by: NeilBrown <neilb@suse.de>
* | Replace all relevant occurrences of -4 with LEVEL_MULTIPATHNeilBrown2009-11-173-7/+7

* | Assemble/super0: allow non-in-sync devices to be assembled without complaint.NeilBrown2009-11-171-1/+8
| | | | | | | | | | | | | | | | Other metadata formats already did not worry about whether 'sync' was missing or not. super0 needs that now, but only for 0.91 metadata that is undergoing reshape. Signed-off-by: NeilBrown <neilb@suse.de>
* | Assemble: include ACTIVE but not in-sync devices as non-spares.NeilBrown2009-11-174-4/+4
| | | | | | | | | | | | | | | | | | Previously such things did not exist: ACTIVE and SYNC were either both set or both clear. Recent changes with reshape means that a device can be ACTIVE but not yet fully in-sync, so they need to be handled and included in the array as active devices. Signed-off-by: NeilBrown <neilb@suse.de>
* | Grow: data_offset is in sectors, offsets[] is in bytes - convertNeilBrown2009-11-161-1/+1
| | | | | | | | | | | | Another missed sectors->bytes conversion. Signed-off-by: NeilBrown <neilb@suse.de>
* | Grow: do not allow size changes with other changes.NeilBrown2009-11-062-0/+18
| | | | | | | | | | | | | | | | | | | | | | A change the reduces the size of an array always happens before any other change. So it can cause data to be lost. By themselves these changes are reversible. But once another change has started, the data would be permanently lost. So recommend data integrity be checked between a size change and any other change.

* | Grow: goto release rather than just returnNeilBrown2009-11-061-4/+8
| | | | | | | | | | | | otherwise we exit with the array frozen. Signed-off-by: NeilBrown <neilb@suse.de>
* | Grow: restrict to 2.6.32NeilBrown2009-11-061-0/+6
| | | | | | | | | | | | | | | | | | 2.6.31 has a bug which can lead to unsafe reshaping. So only allow a reshape with 2.6.32. When the required fixed get into 2.6.31.y, this can be relaxed slightly Signed-off-by: NeilBrown <neilb@suse.de>
* | Grow: use large block count and make sure stripe cache can hold it.NeilBrown2009-11-061-7/+27
| | | | | | | | | | | | | | | | The bigger the backup is, the fast it goes to some extend. 16Meg is fairly arbitrary Signed-off-by: NeilBrown <neilb@suse.de>
* | Grow: get component_size before using it.NeilBrown2009-11-061-4/+5
| | | | | | | | | | | | | | | | We were using ->component_size while it hadn't been set. This effectively meant that 'blocks' wasn't multiplied by 16 and reshape was even slower than it should have been. Signed-off-by: NeilBrown <neilb@suse.de>
* | Grow: handle array going degraded during reshape.NeilBrown2009-11-061-6/+35
| | | | | | | | | | | | | | | | If an array goes degraded during reshape, we need to adjust the devices we read from so as not to back up stale data. Signed-off-by: NeilBrown <neilb@suse.de>
* | Grow: restore backup to proper location.NeilBrown2009-11-061-2/+2
| | | | | | | | | | | | | | | | | | | | The 'arraystart' is in sectors while restore_stripes requires bytes, so we need a conversion. Without this, backups get restored to the wrong offset. Reported-by: "KueiHuan Chen" <kueihuan.chen@gmail.com> Signed-off-by: NeilBrown <neilb@suse.de>

| * Free some malloced memory that wasn't being freed.NeilBrown2009-10-223-2/+8
| | | | | | | | | | | | | | | | | | | | As mdadm is normally a short-lived program it isn't always necessary to free memory that was allocated, as the 'exit()' call will automatically free everything. But it is more obviously correct if the 'free' is there. So this patch add a few calls to 'free' Signed-off-by: NeilBrown <neilb@suse.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Connect to the monitor in the old namespace and use that connection for WaitClean requests when stopping the victim mdmon instance.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Try to execute mdmon from the target namespace.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When killing a previous monitor be careful not to cause writes to the filesystem until the reads necessary to get the monitor operational have completed.

| | * Detail: export MD_UUID from mapfileDan Williams2009-10-133-4/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The load_super() from an mdadm --detail call may race against an mdmon update. When this happens the load_super sees an inconsistent metadata block and returns an error. The fallback path to use the map file contents lacks uuid reporting, so provide __fname_from_uuid for generically printing a uuid.

| | * imsm: add --update=uuid supportDan Williams2009-10-133-12/+47
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When disks have conflicting container memberships (same container ids but incompatible member arrays) --update=uuid can be used to move offenders to a new container id by changing 'orig_family_num'. Note that this only supports random updates of the uuid as the actual uuid is synthesized. We also need to communicate the new 'orig_family_num' value to all disks involved in the update. A new field 'update_private' is added to struct mdinfo to allow this information to be transmitted. Signed-off-by: Dan Williams <dan.j.williams@intel.com>
| | * ddf: prevent superblock being zeroed on --updateDan Williams2009-10-131-8/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The full fix would be to support updating ddf metadata, but this minimal fix just prevents the superblock from being zeroed when someone inadvertently passes an unsupported --update option during assembly.
