I know I can specify mounts in
fstab by either putting their path (like
/dev/mapper/myvg-logicalVolume1) or by fs label (
LABEL=root) or by UUID (
I see a clear advantage in terms of reliability using the UUID for "classic" partitions like
/dev/sda1, because if you repartition your drive/more partitions around/add more disks it may be that your some of your partitions now it gets recognized with another name, although mounting by UUID is more difficult to tell in which partition/LV your data is being stored.
LVM, my guts tell me that the LVM system itself manages the discovery of their disks/partitions and it doesn't matter if some PV is (after playing with partitions/disk) now named different. So there won't be any difference (speaking of reliablity) mounting by UUID or using the path like
/dev/mapper/vg-lv, and the latter is more clear.
Is this correct?
