[Gluster-devel] Gluster volume snapshot - Plugin architecture proposal

[Amar Tumballi]

With Mark Ferrell <https://github.com/major0> too working on this, I
created a github issue <https://github.com/gluster/glusterfs/issues/145>to
track progress. Follow this discussion there if interested.

Ref: https://github.com/gluster/glusterfs/issues/145

Asked relevant folks to be part of the discussion too. Lets take this
forward.
