I'm interested in this as well.
Isn't a RAID-5 array with two missing drives broken?
Has anyone actually tried this? I don't have any spare
drives to play with to test.
The other option is to break the RAID-1, create a new
RAID-5 with the two drives and the third, RAID-1, drive
as the missing drive in the RAID-5 set. Copy over the
data from the RAID-1 drive and then add that drive back
into the RAID-5 array and it should rebuild.
Any thoughts?
Regards,
Kourosh
