Hi,
It's getting clear now, indeed momd service is disabled
● momd.service - Memory Overcommitment Manager Daemon
Loaded: loaded (/usr/lib/systemd/system/momd.service; static; vendor
preset: disabled)
Active: inactive (dead)
mom-vdsm is enable and running.
● mom-vdsm.service - MOM instance configured for VDSM purposes
Loaded: loaded (/usr/lib/systemd/system/mom-vdsm.service; enabled;
vendor preset: enabled)
Active: active (running) since Mon 2017-10-16 15:14:35 CEST; 1min 3s ago
Main PID: 27638 (python)
CGroup: /system.slice/mom-vdsm.service
└─27638 python /usr/sbin/momd -c /etc/vdsm/mom.conf
The reason why I came up with digging in mom problems is the following
problem
*VDSM hostname command GetStatsVDSThanks failed: Connection reset by peer*
that is causing fencing of the node where the failure is happening, what
could be the reason of GetStatsVDS failure?
Best Regards

Hi,
how do you start MOM? MOM is supposed to talk to vdsm, we do not talk
to libvirt directly. The line you posted comes from vdsm and vdsm is
telling you it can't talk to MOM.
Which MOM service is enabled? Because there are two momd and mom-vdsm,
the second one is the one that should be enabled.
Best regards

Hi,
it is just a warning, there is nothing you have to solve unless it
does not resolve itself within a minute or so. If it happens only once
or twice after vdsm or mom restart then you are fine.
