One day cryptsetup will link to liblkid, adding two "use friendly" things in
luksFormat
- warn if it detects something on disk before destroying it
- run wipefs to really destroy all the magic strings there (as Teo suggested)
So valid feature request also on the cryptsetup side, with the same
So what happened is the following. There was a previous ext4 file
system on the disk. You ran "cryptsetup luksFormat /dev/sda1" which
wiped out the primary superblock.
You then manually ran fsck.ext4 on the device. It noticed the primary
superblock was non-existent, and then asked permission
Note: I think this should be a low-priority/wishlist/feature request.
But I can't edit the importance.It is a valid feature request
though, so I plan to treat it at that priority.
If someone else thinks it's higher priority, patches are welcome. :-)
** Changed in: cryptsetup (Ubuntu)
