Of course, you can also mount your encrypted lvm from a live-system and chroot into it to repair your files. I am using encrypted LVM for about a year now and i sometimes do that. I prepared a small script that is saved in my /boot to easily manage that. You have to do the following steps: cryptsetup luksOpen /dev/sdaX tmp vgchange -a y cryptsetup luksOpen /dev/mapper/<name_of_the_vg> <name_of_the_vg> mount /dev/mapper/<name_of_the_vg> mountpoint For me, that looks like: cryptsetup luksOpen /dev/sda6 tmp vgchange -a y cryptsetup luksOpen /dev/mapper/eeepc-root root cryptsetup luksOpen /dev/mapper/eeepc-home home mkdir /mnt/mapper/root mkdir /mnt/mapper/home mount /dev/mapper/root /mnt/mapper/root mount /dev/mapper/home /mnt/mapper/home After doing that, you can access the files, chroot into /mnt/mapper/root etc. -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
