Test I ran: Backup signatures should not be problem, (from the fsck problem POV, not from security/old data on disk POV of course). Tools screams a lot if you want to use these only and primary signature is missing. Anyway, for wiping signature please suggest wipefs(8), this tool is designed to wipe all known signatures. (I am trying to avoid linking cryptsetup to libblkid, but if this happens some time in future, cryptsetup can call wipefs directly.) IOW wipefs -a <device> should destroy all known signatures to blkid (by minimalistic writes, this is not full device wipe, so it is very quick).
