One of the possible scenarios is someone taking a lvm snap of the

As an aside, lvm snapshots are good for one-off temporary saves, but are
completely useless as an interval snapshot. Each one takes up a ton of
ram and increase boot-up times very significantly. I would recommend
focusing on btrfs for any snapshotting backend.
One of the idea is to keep the backend options for taking the snapshot
configurable, so people can use their choice of snapshots. Our main
focus is to get the changes required in gluster{fs,fsd,d} side of things
so we have an option to be given for people wanting to use snapshots.
Main focus of first release would be get the co-ordinated cluster
snapshot working, so in phase2 we will work on approving it on top of
other snapshot options.
