Hello!
I need some help about recover raid1. I have a raid ar0 with two disks.
After first disk fail, I replaced it with new clean disk.
After boot I did:
# natacontrol addspare ar0 ad0
then
# natacontrol rebuild ar0
I type:
# natacontrol status ar0
and see raid in rebuild state. In a few seconds system hangs and I had
to reboot it. Now I see:
# natacontrol status ar0
ar0: ATA RAID1 subdisks: DOWN ad1 status: DEGRADED
# natacontrol addspare ar0 ad0
natacontrol: ioctl(IOCATARAIDADDSPARE): Device busy
and finaly:
# natacontrol rebuild ar0
natacontrol: ioctl(IOCATARAIDREBUILD): Input/output error
Can someone point me to proper manual about how to recover failed disks
and may be how to recover my current situation.
