Thanks Atin for your answer. I just tried a "gluster v get <volume> cluster.op-version" on my Gluster volume and Option????????????????????????????????? Value?????????????????????????????????? ------????????????????????????????????? -----?????????????????????????????????? cluster.op-version????????????????????? 30706?? Now I am running GlusterFS 3.7.12 on that server, so shouldn't my op-version be 30712 instead ?

This version is been owned?by GlusterD to manage?backward compatibilities and allow clients to use new features. It is very well possible that different peers are running with different gluster version ( I am referring executable version here) but the op-version will be same agreed upon by all the glusterds in the cluster. To give an example here consider a feature is introduced in n + 1 release, if clients/servers are upgraded to n + 1th bits, you would only be able to use this new feature if the op-version is bumped to n + 1. In an upgrade process op-version is not bumped up automatically.
