The above clearly shows that there is SOME kind of LVM information in
/dev/sdc, but again I don't know why the system doesn't seem to deal
with it as I would expect.
You might be able to mount the partition by doing something like.
mount /dev/dm-0 /mnt/mountpoint
Given all the above information, there does not seem to be anything like
/dev/dm-0 that corresponds to /dev/sdc. Again I'm at a loss.
There may be an issue if both lvm partitions have the same
names as you current systems. I don't think it will allow that, you
have to jump thru some hops to make the names different. On my
newer systems I don't use LVM.
I suspect you're right, but I don't know how to do any of that.
