Subject: creating degraded raid1 with imsm metadata

Hello *,

Since Intel's Matrix Storage Manager option ROM doesn't support creating of
degraded arrays I was wondering if I could use mdadm to make one? I had a
very hard time finding documentation about how mdadm is supposed to
work with imsm.

The plan is to make a 2x1TB raid1 with one device missing and then later add
the other disk in once all the data has been copied to the degraded array. So
a typical raid1 migration scenario, which Intel oddly enough doesn't seem to
support with their option ROM.

Not sure if that's possible but have you looked at the Linux RAID wiki on IMSM information?
