* Make incremental mode work with partitionable arraysDoug Ledford2008-10-293-11/+117
| | | | | | | | | | | | | | | | | | | | There were multiple problems with incremental mode and partitionable arrays. Change the logic to pay more attention to what it finds in mdadm.conf when setting up incremental arrays. Modify is_standard to differentiate between a required partitioned name format and an optionally partitioned named format. Modify open_mddev() to know about change to is_standard. Make Incremental differentiate between create default autof setting, command line autof setting, and array specific autof setting, with order of preference being command line, conf file, default. Disable the homehost test in the event there is no match for an array so we can hotplug new arrays into a running machine without them having to exist in mdadm.conf first (a random array number will be picked for the hot plugged array). Honor any name from mdadm.conf that matches the UUID of a device, not just standard names. Verify that the array name as matched in mdadm.conf allows the requested mode of operation and reject attempts to start non-partitionable arrays as partitioned and vice versa.

* Fix NULL pointer oopsDoug Ledford2008-10-291-4/+10
| | | | | | | | | | | RAID10 is the only raid level that uses the avail char array pointer during the enough() operation, so it was the only one that saw this. The code in incremental assumes unconditionally that count_active will allocate the avail char array, that it might be used by enough, and that it will need to be freed afterward. Once you make count_active actually do that, then the oops goes away. Signed-off-by: Doug Ledford <dledford@redhat.com>
* Fix bad metadata formattingDoug Ledford2008-10-283-4/+10
| | | | | | | | | | Certain operations (Detail.c mainly) would print out the metadata of an array in a format that the scan operation in super0.c and super1.c would later reject as unknown when it was found in the mdadm.conf file. Use a consistent format, but also modify the super0 and super1 match methods to accept the other format without complaint. Signed-off-by: Doug Ledford <dledford@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | When adding a device to an array, we check that it is large enough. Currently the check makes sure there is also room for a reasonably sized bitmap. But if the array doesn't have a bitmap, then this test might be too restrictive. So when adding, only insist there is enough space for the current bitmap. When Creating, still require room for the standard sized bitmap. This resolved Debian Bug 500309

| | | | | | | Since we made free_super a superswitch call, we need to be careful that st is non NULL before calling st->ss->free_super(st). Also when updating byteorder there is a chance of a similar NULL deref.

* 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.

* 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.
