Subject: [dm-crypt] [Request] cryptsetup option to fix leftovers from old filesystems
Date: Sun, 30 Aug 2009 18:20:42 +0200 [thread overview]

We have encountered a problem with blkid that is caused by cryptsetup
not cleaning superblocks of old filesystems on luksFormat. The problem
has been fixed in 1.0.7, however old LUKS volumes still suffer from this
problem. Please read this thread for details:
http://thread.gmane.org/gmane.linux.utilities.util-linux-ng/2563
What I would request is an option to "clean" the unused area in the LUKS
header up to the start of the payload, such that for example an old ext2
magic is removed. All that without destroying the used areas in the LUKS
header, of course.
I'm not very familiar with the LUKS code or on-disk format, so I would
be greatful if anyone who is would implement such a feature. Thanks for
your replies.
Thomas
