Hm. This is vaguely intersting to me, as soon I'm going to be moving 8 drives off one server (arranged as 2 md RAID5's, 4 drives each) into a server which already has 4 drives fitted... (configured as various md RAID1 and RAID5 devices) Should I expect any problems? Can I degrade an existing running set into non persistent superblock mode to facilitate with this move?
