I had a RAID 5 (Linux software RAID) server which recently decided not to boot anymore. It seems to be a motherboard problem possibly due to not being protected by a UPS during a power failure. It managed to extend its slow death to the point of taking up plenty of my time without much reward but I know that the drives are fine.
Is it possible to rebuild the RAID array even though the drives will have different numbers by plugging it into a machine over USB adapters?
Is it possible any damage can be done to the array in the process by attempting to rebuild the array with the wrong drive numbers?
I don't want to do a
mdadm assemble --force unless I know it's safe. Is there something I can do to investigate if it will be safe to force the assembly?
