I have a "lost" SW RAID array as described in this question: I have now identified a way to mount one of the original (mirrored) RAID members so as to extract the data from it. Now I would like to get the current RAID setup out of the way (there is currently a set-up on the drives that was wrongly auto-detected in a previous attempt to recover the array). This wrongly auto-detected RAID set-up was created using mdadm --assemble --scan and now several RAID (or LVM - I don't know) devices appear:


Only /dev/dm-1 appears to be active. Is is safe to use dmsetup remove to remove these set-ups? That is, will this only remove the meta data about the RAID setups and safely leave the partitions on the member devices unaltered?
