[ovirt-users] Re: Dead agent
Thanks for the reply.
I had already checked what you suggested. I didn't realize that the
engine was used only for management, I had assumed that if it crashes it
would take down all the VMs.
ovirt-ha-broker seems to have crashed. In the borker.log I see:
RuntimeError: Couldn't connect to VDSM within 60 seconds
Thread-3::ERROR::2022-06-16
08:35:02,857::submonitor_base::119::ovirt_hosted_engine_ha.broker.submonitor_base.SubmonitorBase::(_worker)
Error executing submonitor mem-free, args {'address': '0',
'use_ssl': 'true'}
hosted-engine --vm-status tells me that the agent has stopped.
If I do "hosted-engine --vm-start" what will happen to the running VMs ?
Since it's only used for management, if it detects that they are already
running, will it ignore them and go on it's merry way ? I'm trying to
avoid shutting down all the servers if I can help it.

If the engine is down, the VMs will continue to run. You just won't
be able to start/migrate/configure/etc them.
If the engine VM is still running, you may want to SSH into it and
look at the state of the system to see if you can see what went wrong.
systemctl status 'ovirt*' may tell you if just a single service is
down (such as ovirt-engine). You might also check the logs in
/var/log/ovirt-engine
If the VM is down or inaccessible, SSH into one of the hosts capable
of running the engine and run the following to check VM status:
hosted-engine --vm-status
This should tell you if and whre it's running. If it isn't dead, You
can stop it with:
hosted-engine --vm-shutdown
Check the status and wait until it's actually down, then you can start
it up again:
hosted-engine --vm-start
