Since the sdc2 is an lvm partition, you don't mount it via the mount
command. You need to mount the lvm partitions within it.
What does cat /proc/partitions show.
On my system I get this.
major minor #blocks name
8 0 488386584 sda
8 1 204800 sda1
8 2 32696288 sda2
8 3 455482912 sda3
253 0 27123712 dm-0
253 1 5570560 dm-1
sda is the disk
sda1 is the boot partition
sda2 is the lvm partition
sda3 os another partition
dm-0 is the root partition of the LVM
dm-1 is the swap partition
sfdisk -l
will report on the disk
Another command that shows info.

You might be able to mount the partition by doing something like.
mount /dev/dm-0 /mnt/mountpoint
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.
