glustershd process needs to be restarted for every volume start/stop operations to ensure that glustershd can run with the latest volfiles. Currently due to the lack of client graph switch issue, a reconfigure isn't possible for such case with out a restart. volume set operation is still a TODO item and this PR doesn't cover this. Fixes: gluster#1459 Signed-off-by: Atin Mukherjee <amukherj@redhat.com>

glustershd will not be enabled with GCS/1.0. client side self heal can still heal the files in case there's a catch up to do when such a file under question is accessed from the mount point. |
