Hi!
Hosted engine reboots itself almost daily. Is this by design? If not,
where should I be searching for the clues why it shuts down? Someone
is giving reboot order to HE because /var/log/messages in contains
this:
Mar 19 12:05:00 ovirtmgr qemu-ga: info: guest-shutdown called, mode: powerdown
Mar 19 12:05:00 ovirtmgr systemd: Started Delayed Shutdown Service.
And I'm still running v4.3.0 because upgrade to that was bit painful
and haven't dared to new round.
Thanks,
-Juhani

Hi,
Can you check if the he vm fqdn resolves to it's ip from all the hosts?

I checked both hosts and DNS resolving works fine. Just occurred to me
that I also added addresses to /etc/hosts just in case DNS fails. Can
this cause problems? I noticed that this message was in events hour
before reboot:
Invalid status on Data Center Default. Setting status to Non Responsive.
Same event happened just after reboot.

It should not affect.
Can
this cause problems? I noticed that this message was in events hour

@Sahina Bose <sabose(a)redhat.com> what can cause such?
Invalid status on Data Center Default. Setting status to Non
Responsive.
Same event happened just after reboot.
-Juhani
Can you also check the vdsm logs for any anomaly around the time of reboot .

Couldn't find anything that jumps as problem but another post in list
made me check ha-agent logs. This is the reason for reboot:
MainThread::INFO::2019-03-19

So HA-agent does the reboot. Now the question is: What that
'Penalizing score by 1600 due to gateway status' means? Other HA VM's
don't seen to have any problems.

It seems that either our firewall is not responding to pings or
something else is wrong. Looking at the broker.log this can be seen.
Curious thing is that the reboot happens even when ping comes back in
couple of seconds. Is there timeout in ping or does it fire them in
quick succession?

I don't know much of Python, but I think there is a problem with
broker/ping.py. I noticed that these ping failures happen every

I monitored the firewall and network traffic in host and ping works
but that ping.py somehow thinks that it did not get replies. I can't

No failed pings to be seen. So how that ping.py decides that 4 out of 5
failed??
It's just calling the system ping utility as an external process checking
the exit code.
I don't see any issue with that approach.
Can you please try executing:
while true;
do ping -c 1 -W 2 10.168.8.1 > /dev/null; echo $?; sleep 0.5;
done
Thanks,
Juhani

I was looking at the same thing but I can also see that packets reach
the host NIC. I just read the times again and it seems that first ping
was delayed (took over 2 secs). So is that 4 out of 5 number of
succeeded pings? Because I read it the other way.
