Public bug reported:
Binary package hint: mdadm
I'm on Ubuntu 10.10, when I tried to boot with the 2.6.35-28 kernel, for
some reason on boot md tries to assemble my devices incorrectly, using
the whole devices rather than the partitions. The software raid device
starts, but then LVM cannot find the disk group.
e.g. Here is the output from dmesg on the 2.6.35-27 kernel, which does
work properly:
md/raid:md0: device sdf1 operational as raid disk 1
md/raid:md0: device sde1 operational as raid disk 0
md/raid:md0: device sdd1 operational as raid disk 2
md/raid:md0: allocated 3179kB
md/raid:md0: raid level 5 active with 3 out of 3 devices, algorithm 2
RAID conf printout:
--- level:5 rd:3 wd:3
disk 0, o:1, dev:sde1
disk 1, o:1, dev:sdf1
disk 2, o:1, dev:sdd1
md0: detected capacity change from 0 to 2000407494656
md0: unknown partition table
Here is the output form 2.6.35-28 which does not work properly:
md/raid:md0: device sdd operational as raid disk 2
md/raid:md0: device sdf operational as raid disk 1
md/raid:md0: device sde operational as raid disk 0
md/raid:md0: allocated 3179kB
md/raid:md0: raid level 5 active with 3 out of 3 devices, algorithm 2
RAID conf printout:
--- level:5 rd:3 wd:3
disk 0, o:1, dev:sde
disk 1, o:1, dev:sdf
disk 2, o:1, dev:sdd
md0: detected capacity change from 0 to 2000407494656
md0: p1
My md0 device should not have a p1 partition on it!
