hi,
I have a RAID1 array (md1) with two partitions (/dev/sda1 and /dev/sdb1).

Earlier today, I replaced /dev/sda because it had errors (reported by smartd/smartctl)
# mdadm /dev/md0 -f /dev/sda1 -r /dev/sda1
# mdadm /dev/md1 -f /dev/sda2 -r /dev/sda2

I replaced and formatted the drive and added it to the RAID1 arrays:

# mdadm /dev/md0 -a /dev/sda1
# mdadm /dev/md1 -a /dev/sda2

Everything looked great at first:
# cat /proc/mdstat 
Personalities : [raid1] 
md0 : active raid1 sda1[0] sdb1[1]
      521984 blocks [2/2] [UU]
      
md1 : active raid1 sda2[2] sdb2[1]
      976237824 blocks [2/1] [_U]
      [====>................]  recovery = 22.4% (219600512/976237824) finish=131.5min speed=95860K/sec
      
unused devices: <none>


But the sync restarted w/o error.

So, I ran:
# smartctl -a /dev/sdb

... which returned 3 errors.

After the second time the sync restarted, smartctl reported 24 errors on /dev/sdb. It has restarted a few times since then, but smartctl reports the same number of errors (24).

I'm enclosing the output from 'smartctl -a /dev/sdb'.
I tried to run a short selftest, but aborted it after 10 minutes. I was concerned that I shouldn't run a selftest at the same time it's rebuilding.

For what it's worth, I can't pause the sync. The command:

# echo idle > /sys/block/md1/md/sync_action

... has apparently no effect.

Can anybody make a recommendation? I'd rather not reboot, but I have a planned outage scheduled Friday.

Thanks in advance for any help,
Julie
