Hi,
following situation:
I've a degraded raid1 on a Intel fake raid. I could add the new hdd (sdb)
to imsm0, (via mdadm -a /dev/md/imsm0 /dev/sdb). But the members (Volume0
and Volume1) don't recover.
How can I add the new hdd to the Volumes, or start the recovery process?
Best regards,
Michael Fritscher
