[Gluster-devel] Question on merging zfs snapshot support into the mainline glusterfs

      Is there a plan to come up with an interface for snapshot
functionality? For example, in handling different types of sockets in
gluster all we need to do is to specify which interface we want to use and
ib,network-socket,unix-domain sockets all implement the interface. The code
doesn't have to assume anything about underlying socket type. Do you guys
think it is a worthwhile effort to separate out the logic of interface and
the code which uses snapshots? I see quite a few of if (strcmp ("zfs",
fstype)) code which can all be removed if we do this. Giving btrfs
snapshots in future will be a breeze as well, this way? All we need to do
is implementing snapshot interface using btrfs snapshot commands. I am not
talking about this patch per se. Just wanted to seek your inputs about
future plans for ease of maintaining the feature.
