Yup.
fdisk /dev/sda
p
and look at the partition listing, to make sure that it really is being seen as
/dev/sda.

As a last resort, you could burn yourself a copy of knoppix, and boot off that,
which gives you a full-blown Linux, and then look more... It usually can
identify all hardware.

Couldn't it be that in rescue mode the LVM isn't activated?

/dev/sda2 isn't really the file system you're trying to mount, but
rather the physical volume. You want to mount the logical volume of the
volume group created on this PV. The LV will be something like
/dev/vg0/volX.


Try 'vgchange -an' and then mount the LV with something like mount
/dev/vg0/volX /mnt.
