glusterd: Start rebalance only where required
Gluster was starting rebalance processes on peers where it wasn't required in two cases. - For a normal rebalance command on a volume, rebalance processes were started on all peers instead of just the peers which contain bricks of the volume - For rebalance process being restarted by a volume sync, caused by a new peer being probed or a peer restarting, rebalance processes were started on all peers, for both a normal rebalance and for remove-brick needing rebalance. This patch adds a new check before starting rebalance process in the above two cases. - For rebalance process required by a rebalance command, each peer will check if it contains atleast one brick of the volume - For rebalance process required by a remove-brick command, each peer will check if it contains atleast one of the bricks being removed Change-Id: I512da16994f0d5482889c3a009c46dc20a8a15bb BUG: 1031887 Signed-off-by: Kaushal M <kaushal@redhat.com> Reviewed-on: http://review.gluster.org/6301 Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Krutika Dhananjay <kdhananj@redhat.com> Reviewed-by: Anand Avati <avati@redhat.com>
