How do you mount a LVM patition that has the same VG name as my current partition
I had a similar issue on my system. I just renamed the external logical volume group.
Beware that this probably makes the renamed drive unbootable! I don't know which files you have to change so you can boot again afterwards.
First get UUID of group to rename. I used
$ sudo vgdisplay
--- Volume group ---
VG Name mint-vg
System ID
Format lvm2
Metadata Areas 1
Metadata Sequence No 3
VG Access read/write
VG Status resizable
MAX LV 0
Cur LV 2
Open LV 0
Max PV 0
Cur PV 1
Act PV 1
VG Size 119,00 GiB
PE Size 4,00 MiB
Total PE 30464
Alloc PE / Size 30464 / 119,00 GiB
Free PE / Size 0 / 0
VG UUID jWIQCX-uxUT-aG1x-1tpc-1Ixk-pxw2-gL6mlJ

VG UUID TZus4Q-JQKU-eyyl-kkEv-liM4-mUXd-e19TcT
I want to rename the first one. Because this is my thumb drive.
Now I know the UUID and can execute a rename. Maybe a mount could also work with the UUID but I didn't care about it.
$ sudo vgrename -v jWIQCX-uxUT-aG1x-1tpc-1Ixk-pxw2-gL6mlJ mint-stick

To mount an external hard-disk (LVM2 and EXT4 partitions):
Check the UID number of the hard-disk
sudo vgdisplay
Mount your hard-disk:
sudo vgrename <UID> volgroup
Activate the mount volume:
sudo vgchange -a y
