Have you verified that you have a new UUID for that old backed-up
partitiion. IIRC, when one backs up a partition using 'dd
if=/dev/sd{n}{x}', the old UUID is part of the data backed up.
code:
ls -l /dev/disk/by-uuid
If my guess is correct, for a hypothetical partition sdz9, your fix
should be something like:
code:
tune2fs /dev/sdz9 -U $(uuidgen)
