cryptsetup

hi,

i try to encrypt logical volumes, but it seems, that it doesn't work. Can i use only real partitions?

I have several virtual hosts with Xen and every hosts has it own data and swap volume. For example:

ACTIVE            '/dev/daten/vhost1_swap' [500.00 MB] inherit
ACTIVE            '/dev/daten/vhost2_swap' [500.00 MB] inherit
ACTIVE            '/dev/daten/vhost3_swap' [500.00 MB] inherit
ACTIVE            '/dev/daten/vhost4_swap' [500.00 MB] inherit
ACTIVE            '/dev/daten/irc_swap' [500.00 MB] inherit
ACTIVE            '/dev/daten/mx_swap' [500.00 MB] inherit
ACTIVE            '/dev/daten/vhost4_daten' [100.00 GB] inherit

PV /dev/hda8   VG daten        lvm2 [92.58 GB / 0    free]
PV /dev/hdc8   VG daten        lvm2 [92.58 GB / 82.23 GB free]

I these example, i want to crypt /dev/daten/vhost4_daten:

root@xendom0:~# cryptsetup -y create data /dev/daten/vhost4_daten
Command failed: Invalid argument

So, what for options i have?

it was my fault. I compiled the wrong cryptsetup version without luks extension. I tried allready the version from breezy and it let me type the password, but nothing more.

Now i have the static compiled version from here:
http://luks.endorphin.org/ and i was able to create the crypted logical volume :-)

thanks.
