No; LVM2 sits a level above partitioning. If you had a partition table on the devices that were being used by LVM2 when you backed up you should put it back before you restore (and back it up separately of course). Note also that if you were using partitions then you'll need to re-create the PVs on the appropriate partitions after restoring those before you can restore the LVM2 metadata. If you're just using whole-disk devices then there are no partitions or partition tables to worry about. If you mean partition tables that are stored _inside_ logical volumes (e.g. where the LV is a whole-disk image for a virtual machine containing partitions) then the answer's no as well; in this case the partition table is just ordinary data on the LV and LVM2 doesn't know or care about it at all (so you need to back it up separately, just like any other data stored in an LV). > I recently recovered an LVM that had a partition inside of it, but it has since > been unable to mount.

Run the tools agains the logical volume (LV), not the physical volume (PV).
