This is a multi-part message in MIME format. --------------BD80C71AA18C6FFCFC3029E1 Content-Type: text/plain; charset=utf-8 Content-Transfer-Encoding: 8bit Hi, 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. Also, can you provide the engine and the vdsm logs? thank you, Dafna On 10/16/2017 02:30 PM, Erekle Magradze wrote:
It's was a typo in the failure message,
that's what I was getting:
*VDSM hostname command GetStatsVDS failed: Connection reset by peer*

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 Erekle

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 Martin,
Thanks for the answer, unfortunately this warning message persists, does it mean that mom cannot communicate with libvirt? how critical is it?

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.

Hi,
after running
systemctl status vdsm I am getting that it's running and this message at the end.
Oct 16 14:26:52 hostname vdsmd[2392]: vdsm throttled WARN MOM not available. Oct 16 14:26:52 hostname vdsmd[2392]: vdsm throttled WARN MOM not available, KSM stats will be missing. Oct 16 14:26:57 hostname vdsmd[2392]: vdsm root WARN ping was deprecated in favor of ping2 and confirmConnectivity
how critical it is? and how to solve that warning?
I am using libvirt
