Hi,
The issue is the following, after installation of ovirt 4.1 on
three nodes with glusterFS as a storage, oVirt engine reported the
failed events, with the following message
VDSM hostname command GetStatsVDS failed: Connection reset by peer
after that oVirt was trying to fence the affected host and it was excluded from production, luckily I am not running any VMs on it yet.
The logs are attached, don't be surprised with the hostnames :)
Thanks in advance
Cheers
ErekleHi,
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

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.

If it happens only once or twice after vdsm or mom restart then you are fine.
