mdadm – Attempted to move raid array to new system, superblocks gone?
I attempted to move a mdadm raid 1 array to a different system this evening.
I took the 2 SSDs out of one system and put them in another, then booted that system.
I opened gparted to check what the disks appeared as. They showed up as being blank (unallocated) drives.
I then shut down this system and moved the drives back to the original system, and booted.
sudo mdadm --assemble --scan --verbose
reported that no raid superblocks were found on
sgh, which is where I would expect the data to be.
I thought this should be a fairly trivial process, but I’m now not sure what to do.
Any help would be appreciated, it’s kind of important I don’t loose the data on these drives…
