Package: mdcfg Version: 1.24 During an installation test I was working in a virtual machine with two disks. The second harddisk still had two partitions previously used for RAID tests while the first hard disk had been reused in the mean time.
For the second hard disk one of the partitions was part of a RAID1, the
other of RAID0. The first was correctly started (degraded), but the second
obviously failed to start.
# cat /proc/mdstat
Personalities : [raid0] [raid1] [raid6] [raid5] [raid4]
md1 : inactive hdd2[1]
xxxxx blocks
md0 : active raid1 hdd1[1]
yyyyy blocks [2/1] [_U]
unused devices: <none>
This resulted in a broken dialog when selecting to delete a RAID device:
Multidisk device to be deleted:
md1
:
inactive
hdd2[1]
md0_raid1
Cancel
The first 4 lines are clearly due to incorrect parsing from /proc/mdstat.
After selecting the first line (md1), the next confirmation dialog did look
OK, but the actual deletion failed partially and resulted in an error
dialog. From the syslog:
mdcfg: Removing /dev/md/1 (Started /dev/hdd2)
kernel: md: md1 stopped.
kernel: md: unbind<hdd2>
kernel: md: export_rdev(hdd2)
mdcfg: mdadm: stopped /dev/md/1
mdcfg: mdadm: Couldn't open Started for write - not zeroing
Again this looks like a parse error.
