Hi Piotr,
Several times I've restarted vdsm daemon on certain nods, that could be
the reason.
The failure, I've mentioned, has happened yesterday from 15:00 to 17:00
Cheers

Erekle,
In the logs you provided I see:
IOError: [Errno 5] _handleRequests._checkForMail - Could not read
mailbox:
/rhev/data-center/6d52512e-1c02-4509-880a-bf57cbad4bdf/mastersd/dom_md/inbox
and
StorageDomainMasterError: Error validating master storage domain: ('MD
read error',)
which seems to be cause for vdsm being killed by sanlock which caused
connection reset by peer.
After vdsm restart storage looks good.
@Nir can you take a look?
Thanks,
Piotr

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

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

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

mom-vdsm is enable and running.

Main PID: 27638 (python)

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

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
