A generic warning is there: # cryptsetup luksHeaderRestore /dev/sdb --header-backup-file /luks-bck.img WARNING! ======== Device /dev/sdb does not contain LUKS2 header. Replacing header can destroy data on that device. ... Just is should say what filesystem is there (we do this check on luksFormat already): through libblkid: # cryptsetup luksFormat /dev/sdb WARNING: Device /dev/sdb already contains a 'ext4' superblock signature. ... so it is really just trivial fix.
