HI,
We are currently running a three node cluster, on Gluster 3.6.4.
On one of our nodes we noticed that the glusterd daemon is dead.
But the glusterfsd daemons are still running, and we believe clients are connecting and retrieving data
We noticed that the daemon has been dead for a week, and we didn't see it.
We would like to know are we safe to just go ahead and start the glusterd service again.
It can be started safely as mgmt & i/o path do not interfere with each other.
If so would this trigger a self-heal on all volumes? As this would cause a performance issue.
Why would you need a self heal trigger if all of your bricks w(a)are running.
The logs for this node is as follows::

If we aren't safe to do so, what else should we do to resolve this?
