Not really no array -- this remnant is inactive. On older kernel /
mdadm combinations, you have to --stop the inactive array before you try
again. Please add --verbose to your --assemble --force
If that doesn't work, use a bootable thumb drive with current kernel and
mdadm and --assemble --force again.
Phil
