<div class="moz-cite-prefix">Hi, <br>
<br>
Can you please tell us what is the issue that you are actually
facing? :) it would be easier to debug an issue and not an error
message that can be cause by several things. <br>
<br>
Also, can you provide the engine and the vdsm logs? <br>
<br>
thank you, <br>
Dafna<br>

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

<pre wrap="">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

<pre wrap="">Hi Martin,
Thanks for the answer, unfortunately this warning message persists, does it
mean that mom cannot communicate with libvirt? how critical is it?
Best

<pre wrap="">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.
Best regards
