I'm not sure how to do that when I can't even mount the disk.
you can use, eg,
dd if=/dev/sda1 of=/home/fred/sda1-image
to get a bit-for-bit copy of the /dev/sda1 partition as a file on some
other filesystem... only do it when the filesystem being copied is
unmounted. If you don't have recent backups of the important content,
that was great advice to rip a copy of your partition(s) before you meddle.
Any suggestions on what to do next?
I think job #1 is to start hating on LVM. I didn't really understand
what you have done to your system and if you took a dump on the ext3
filesystem inside the LVM wrapper or not, or if you merely trashed the
LVM metadata. But either way at this bad moment you are in poorly
charted territory and not much help is forthcoming if my experience was
any guide. That's *exactly* the situation you *don't* want your *data*
of all things to be in. I took from this that LVM is just a bomb
waiting to go off and have removed it from all my boxes, and
periodically rant here to a perfect disinterest from anyone capable to
change it that LVM should NOT be on by default for installs.
I documented here:
how I recovered an ext3 filesystem from a trashed LVM partition, it's
not trivial but it worked. If you have backups, you should instead give
up and repartition and reformat your drive plain ext3 (if you are in the
mood for taking advice, partition as a single / partition and maybe a
little one for /boot first).
