I see that lvcreate cannot create a snapshot volume from another
snapshot volume. It gives an error message about snapshots of
snapshots being "not supported yet".
As an alternative, is there any way to duplicate (not snapshot) a
snapshot volume, i.e. so the new snapshot shares the same source and
accumulated differences as the original snapshot?
I assume copying the snapshot with dd would produce a flat, non-
snapshot volume, but I want my copy to still be a snapshot.
Context: I'm running a bunch of Xen VM's. I have a base logical volume
from which snapshots are made, one for each Xen VM. But I want to go
one step further, with multiple snapshots per VM.
