Ssh to host and check the status of :
sanlock.service
supervdsmd.service
vdsmd.service
ovirt-ha-broker.service
ovirt-ha-agent.service

For example if sanlock is working, but supervdsmd is not - try to restart it.
If it fais, run:
systemctl cat supervdsmd.service

And execute the commands in sections:
ExecStartPre
ExecStart

And report any issues, then follow the next service in the chain.
