Subject: [ovirt-users] Re: ovirt-engine unresponsive - how to rescue?
I've now shut down the VMs on one host and rebooted it but the agent service
doesn't start. If I run 'hosted-engine --vm-status' I get:
The hosted engine configuration has not been retrieved from shared storage. Please ensure
that ovirt-ha-agent is running and the storage server is reachable.
and indeed if I list the mounts under /rhev/data-center/mnt, only one of the directories
is mounted. I have 3 NFS mounts, one ISO Domain and two Data Domains. Only one Data
Domain has mounted and this has lots of .prob files in. So why haven't the other NFS
exports been mounted?
Manually mounting them doesn't seem to have helped much either. I can start the
broker service but the agent service says no. Same error as the one in my last email.

Right, still down. I've run virsh and it doesn't know anything about the engine

I've restarted the broker and agent services and I still get nothing in
virsh->list.
In the logs under /var/log/ovirt-hosted-engine-ha I see lots of errors:

On the host you tried to restart the engine on:
Add an alias to virsh (authenticates with virsh_auth.conf)
alias virsh='virsh -c

Then run virsh:

This has to be resolved:
Engine status : unknown stale-data
Run again 'hosted-engine --vm-status'. If it remains the same, restart
ovirt-ha-broker.service & ovirt-ha-agent.service
Verify that the engine's storage is available. Then monitor the broker & agent
logs in /var/log/ovirt-hosted-engine-ha
