[Gluster-users] glusterd-locks.c:572:glusterd_mgmt_v3_lock

OK, on my nagios instance I've disabled gluster status check on all
nodes except on one, I'll check if this is enough.

Thanks,

    Paolo

[Gluster-users] glusterd-locks.c:572:glusterd_mgmt_v3_lock

Hi Atin,

I've initially disabled gluster status check on all nodes except on one
on my nagios instance as you recommended but this issue happens again.

So I've disabled it on each nodes but the error happens again, currently
only oVirt is monitoring gluster.

I cannot modify this behaviour in the oVirt GUI, there is anything that
could I do from the gluster prospective to solve this issue? Considering
that 3.8 is near EOL also upgrading to 3.10 could be an option.


Greetings,

    Paolo

[Gluster-users] glusterd-locks.c:572:glusterd_mgmt_v3_lock

shouldn't get into this situation. Can you please help me with the latest
cmd_history & glusterd log files from all the nodes?
