fine.   In rescue mode, you can do debugfs or "e2fsck -f -b 32768.."   on the /dev/mapper/volume and try to get a good superblock and correct the filesystem.

right,


I am actually thinking about moving the date to another machine and/or
put it on another device.
(the rescue cd gives me the option to activate the network interfaces,
that way I could scp or ftp it to another machine and inspect the
retrieved data before anything else.)
