[Gluster-users] glusterd daemon dead, but glusterfsd still running

[Matthew Wade]

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.

If so would this trigger a self-heal on all volumes? As this would cause a 
performance issue.

The logs for this node is as follows::

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