It is possible that the problem lies with cryptsetup. Even when
manually performing the steps
cryptsetup luksOpen /dev/sdb1 luks
cryptsetup luksClose luks
I still end up with some "leaked" devices. These can cause the "already
setup" error. For example I have
/org/freedesktop/Hal/devices/volume_part_1_size_64000
[EMAIL PROTECTED] cryptsetup-1.0.5]$ lshal -l -u

This temporary-cryptsetup-XXXXX device is created by cryptsetup
luksOpen, but it was supposed to be freed by clear_mapping().
By the way, my Fedora 7 box does this perfectly. You might want to see
what is different with that.
