Hello,
I have a 2 disk RAID1 array, /dev/sda2 and /dev/sdb2. sda has failed, at
least won't run reliably for very long. sdb2 has taken over and is acting as
the data source for the array.
I had tried to re-use the drive after a reformat. What I did was a straight
forward:
raidhotadd /dev/md0 /dev/sda2
What happened was sda2 was added as a spare disk, mirror 2. The disks resynced
and I rebooted, but the array kept using sda2 as mirror 2. The config file in
/etc/raidtab says that /dev/sda2 is supposed to be mirror 0.
The drive has failed again, and I have replaced it. The array is currently
running on /dev/sdb2 in degraded mode. What I need to know is how to get sda2
back into the array as mirror 0 as it should be.
Something of a raid recovery howto would be a good thing.
