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?
