Public bug reported:
Binary package hint: gnome-disk-utility
I have now managed to produce an unusable luks partition 4 times. 2
times with the mint rc (karmic based) loopback mounted from hd via grub2
and now 2 times with lucid 20100210 64 bit daily iso loopback mounted
from a usb stick via grub2 on a different notebook.
Here is how:
use gparted to make space by making the main partition shorter. I made empty
space of about 10GB at the end of the disk.
use palimpsest to put an encrypted partition in this newly created empty space.
tried with both ext4 and ext3. used default options.
the filesystem is created and can be mounted. put stuff in. unmount. shut down.
on reboot there is no luks partition anymore: gparted says "unknown" and
palimpsest says "unrecognised"
sudo most /dev/sdax shows that partition has no luks header. a lot of zeros at
the beginning instead.
when using palimpsest in the same manner on this faulty partition again
to overwrite it with another encrypted partition all worked well.
