Hi Anton,
I am not sure if changing this value would fix the issue. Defaults are
pretty high. For example vdsHeartbeatInSeconds=30seconds,
vdsTimeout=180seconds, vdsConnectionTimeout=20seconds.
Do you still have relevant logs from the affected hosts:
* /var/logs/vdsm/vdsm.log*
* /var/logs/vdsm/supervdsm.log*
Please look for any jsonrpc errors ie. write/read errors or (connection)
timeouts. Storage related warnings/errors might also be relevant.
Plus system logs if possible:
*journalctl -f /usr/share/vdsm/vdsmd*
*journalctl -f /usr/sbin/libvirtd*
In order to get system logs from particular time period please combine it
with the following example using -S -U options:
*journalctl -S "2020-01-12 07:00:00" -U "2020-01-12 07:15:00" *
I haven't a clue what to look there for besides any warnings/errors or
anything else that seems .... unusual.

Hi Everybody,
Did some digging around, and saw a few things regarding “vdsHeartbeatInSeconds”
I had a look at the properties file located at
/etc/ovirt-engine/engine-config/engine-config.properties, and do not see an entry for
“vdsHeartbeatInSeconds.type=Integer”.
Seeing as these data centers are geographically split, could the “vdsHeartbeatInSeconds”
potentially be the issue? Is it safe to increase this value after I add
“vdsHeartbeatInSeconds.type=Integer” into my engine-config.properties file?
Thanks

*Subject:* [ovirt-users] Random hosts disconnects
Hi All,
I have a strange issue in my oVirt environment. I currently have a
standalone manager which is running in VMware. In my oVirt environment, I
have two Data Centers. The manager is currently sitting on the same subnet
as DC1. Randomly, hosts in DC2 will say “Not Responding” and then 2 seconds
later, the hosts will activate again.
The strange thing is, when the manager was sitting on the same subnet as
DC2, hosts in DC1 will randomly say “Not Responding”
I have tried going through the logs, but I cannot see anything out of the
ordinary regarding why the hosts would drop connection. I have attached the
engine.log for anybody that would like to do a spot check.
Thanks
