I don’t buy that, but I don’t use Clonezilla so I might be overly optimistic.
I do know that GParted (which does not “clone”) does not support LVM2 at all.
You do have three physical drives, three PV in them, one VG spanning all three, and LVs in the VG (of which the “home” likely uses extents from all three PVs). Furthermore, the “home” is unshrinkable XFS?
If one could connect fourth drive, then one could create one more PV there, add to the VG, pvmove extents from other PV, and finally remove the empty PV from VG (and drive from system). That would be “LVM way”.
A drive has partition table and at least one partition. Cloning whole disk ought to replicate both that metadata and whatever is within the partition (including UUID’s, etc). It is obvious that one cannot copy all bits into smaller disk, but going to clearly larger disk should not be an issue. Result of clone&replace should have looked like the “identical to old”, unless something was not copied – outsiders refer to identifiers that did not clone.
Anyway, if your LV spans multiple sticks, then you have even more reason to maintain a backup of the contents.
