If anybody has any suggestions on how to rebuild RAID sets (or
pointers to a good HOWTO), that would be very much appreciated.
I've never used Sarge so I don't know what md tools exist in that
environment. To rebuild a raid using mdadm, it's as simple as this:
# mdadm --remove /dev/md0 /dev/hdb1
Then replace the disk with the good one.
# mdadm --add /dev/md0 /dev/hdb1
well that seems to almost work
on 3 of 4 raid sets, this works, the mirrors resync and all is good
on the 4th raid set, after adding 2 drives (partitions) to the set,
mdadm --detail /dev/md2 shows
/dev/md2:
Version : 00.90.01
Creation Time : Thu Jul 20 06:15:18 2006
Raid Level : raid1
Device Size : 97659008 (93.13 GiB 100.00 GB)

State : active, degraded
Active Devices : 0
Working Devices : 3
Failed Devices : 0

Number Major Minor RaidDevice State
0 8 51 0 spare rebuilding /dev/sdd3
1 8 35 1 spare rebuilding /dev/sdc3
2 8 19 - spare /dev/sdb3
and cat /proc/mdstat shows:
md2 : inactive sdc3[1] sdd3[0] sdb3[2]
292977024 blocks
any idea what "rebuilding" means and why mdadm shows active, while
/proc/mdstat shows inactive?
more to the point, what do I do about this?
Thanks,
Miles
