Any lvm users/experts here?  Redhat's search on the linux-lvm list is
broken and I've asked this question on the list and got exactly 0
responses.  So here goes.
I want to take a snapshot of a filesystem (~300 GB), let testers make
changes, then throw away all those changes and revert to the state of
the original snapshot.  Basically, I want to throw away all the
changes written to the COW, not apply them back to the original
Anybody know if that's possible, or how to do it?
