Reply-To: LVM general discussion and development List-Id: LVM general discussion and development List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , List-Id: Content-Type: text/plain; charset="us-ascii" To: linux-lvm@redhat.com I notice that lvm now has the ability to merge the snapshot changes back into the origin effectively throwing out the old volume and keeping the new, but I was wondering if it is possible to decide to keep BOTH? In other words, try out some experimental changes to the snapshot, then decide to keep it, without throwing out the origin? In other words, finish copying all of the blocks not already on the exception list so you have two complete volumes. Also I noticed that the man page for lvconvert says it can convert a regular volume into a snapshot of another. This does not make sense to me. Is this this the same as deleting the volume to free up space then creating a new snapshot of the origin using that free space?
