If there are features which need to be explicitly turned on by volume set interface, you'd still need to do that to get the feature work.> > Is there a list somewhere of changes from op-version=2 to > op-version=30710 and what features are automatically enabled and/or > disabled with each op-version version?Unfortunately there is no such document. But I can take you through couple of code files [1] [2] where the first one defines all the volume tunables and their respective supported op-version where the later has the exact number of all those version variables.

Looks like I have some research to do to figure out if any of the features released since op-version=2 would be useful for us. Is there any documentation outlining "recommended" settings for a 2 server replicated setup running the latest version of Gluster? Thanks, -Dj
