From 02d653931c8967accf766014efce0c2dce340cdf Mon Sep 17 00:00:00 2001 From: Kaushal M Date: Wed, 28 Nov 2012 16:22:15 +0530 Subject: glusterd,glusterfsd,libgfapi: Client op-version This patch introduces op-version support for glusterfs clients. Now, a client sends its supported op-versions during the volfile fetch request and glusterd will return the volfile only if the client can support the current op-version of the cluster.
