Hi all.
On a SLES 10 SP 3 x86_64 version I'm encountering the following problem:
Two disks sda and sdb are in a RAID 1 configuration. When pulling one
disk and replacing it it becomes sdc instead of sda. The RAID is now
degraded:
kblhbe101:~ # cat /proc/mdstat
Personalities : [raid1] [raid0] [raid5] [raid4] [linear]
md2 : active raid1 sda8[2](F) sdb8[1]
286125568 blocks [2/1] [_U]
md0 : active raid1 sda5[2](F) sdb5[1]
529984 blocks [2/1] [_U]
md3 : active raid1 sda7[2](F) sdb7[1]
4200896 blocks [2/1] [_U]
md1 : active raid1 sda6[2](F) sdb6[1]
2104384 blocks [2/1] [_U]
unused devices:<none>
But now I can't remove the sda partitions from the RAID:
kblhbe101:~ # mdadm /dev/md0 -r /dev/sda5
mdadm: cannot find /dev/sda5: No such file or directory
kblhbe101:~ # mdadm /dev/md0 -r sda5
mdadm: cannot find sda5: No such file or directory
What am I doing wrong here?
kblhbe101:~ # mdadm --version
mdadm - v2.6 - 21 December 2006
Try `mdadm /dev/md0 -r missing`.
Cheers,
John.
