In some situations, you may encounter several volumes (LVM) with same name.
In this case, you can't mount all logical volumes in same time, and you can't use vgrename "OLD NAME" "NEW NAME".
This is an easy solution to
- list physical volumes
- once you get the name of the volume you want, get its VG UUID
- (optional) you can list its logical volumes
- you can now rename this volume (unmount any corresponding logical volume first)
You can now mount all logical volumes.
