I have to disagree; the only tool that uses the backup superblock is e2fsck, and if you accidentally run wipefs on the volume, you should be able to recover it with e2fsck.
If you don't want to attempt to recover a filesystem there, then don't run e2fsck. ** Changed in: util-linux (Ubuntu) Status: New => Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1713175 Title: Obsolete backup ext2/3/4 superblocks can confuse e2fsck on an encrypted LUKS partition To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/cryptsetup/+bug/1713175/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
