I want to replace both disks in a RAID-1 with larger ones using the instructions here: http://linux-raid.osdl.org/index.php/Growing#Extending_an_existing_RAID_array It looks straightforward: mdadm -f, mdmadm -r, swap a drive, etc., etc. Except if I -f & -r a drive, I won't know which physical drive to pull. (And I have no spare SATA ports.) So I figure I'll pull a drive first, then -f & -r whatever mdadm tells me is missing. But when I pull the drive, connect a new one and boot, I get dropped into a repair shell with: fsck.ext3: Unable to resolve 'UUID=806153bf-6917-440d-ae48-553418cfbbeb' which is the UUID of the raid filesystem. I put the drive back in and reboot, and everything is fine. 1) So why doesn't my RAID-1 survive pulling a drive? Seems like a standard failure mode. 2) How do I proceed with the upgrade?
