I have a three node Ovirt cluster where one node has stale-data for the hosted
engine, but the other two nodes do not:
Output of `hosted-engine --vm-status` on a good node:
```

I tried the steps in https://access.redhat.com/discussions/3511881, but
`hosted-engine --vm-status` on the node with stale data shows:
```
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.
```
One the stale node, ovirt-ha-agent and ovirt-ha-broker are continually
restarting. Since it seems the agent depends on the broker, the broker logs
includes this snippet, repeating roughly every 3 seconds:
```

```
I restarted the stale node yesterday, but it still shows stale data from
December of last year.
What is the recommended way for me to try to recover from this?
(This came to my attention when warnings concerning space on the /var/log
partition began popping up.)
Thank you,
Randall
