Re: please HELP - can't acces encrypted LVM after linux reinstallation.

[Aleksander Swirski <aleksanderswirski@xxxxxxxxx>]

thank you for your replies. if someone knows, if it's possible to find

crypt partition wasn't moved or resized, also the home logical volume, which I lost was 'continuous' and
wasn't moved or resized.
