That must be the problem.
Host a has a score of 1800.
Host c has a score of 3400.
I was able to deploy the hosted-engine to Host B through the web UI.
1) Put it in maintenance mode
2) Installation -> Reinstall ... and make sure to select "Deploy" for the hosted-engine
How do I fix / change the score on the first node?
Separately, I'm still confused how I would update oVirt to use the 2nd replica as a mount point. Healing the volume seems to me like a completely different task than reconfiguring oVirt to mount the 2nd replica in its mount options?

Verify that your engine's volume is really OK.
gluster volume info engine
gluster volume status engine
gluster volume heal engine info summary
>I cannot migrate the engine off of c.
And if the engine is running on the other host a, then I turn host c back on, the engine shuts down from a, and comes back up on c.
Check the scores of the systems via 'hosted-engine --vm-status'.
Check vdsm logs on both hosts.
Check the logs in the engine itself.

About a month ago, I completely rebuilt my oVirt cluster, as I needed to move all my hardware from 1 data center to another with minimal downtime.
All my hardware is in the new data center (yay for HIPAA compliance and 24/7 access, unlike the old place!)
I originally built the cluster as a single-node hyperconverged. I then added nodes to it, and then, finally, I reconfigured gluster to run in a replica 2 / arbiter 1 configuration.
As of now:
- I have 4 compute hosts
- Gluster is running fine and replicating fine between the two full replicas, along with the arbiter node
- I need to revisit my recent email about gluster replication speed, though
However, I'm worried about two things:
- I think that my hosts, and hosted-engine, are all still configured to use the single mount point from the original single-node hyperconverged ... i.e. if I shutdown / reboot that host, then the storage "goes away"
- How do I reconfigure oVirt to use the 2nd replica as a secondary mount point?
- Currently, the Engine is deployed on two of the servers (a and c). But any time one of those servers is online (c), the hosted-engine insists on running on that server c. I cannot migrate the engine off of c.
And if the engine is running on the other host a, then I turn host c back on, the engine shuts down from a, and comes back up on c. - How do I "fix" this so that the engine will run on host a, even when host c is turned on?
- How do I deploy the hosted-engine to host b?
- Is it as simple as logging into host b, and running "hosted-engine --deploy" ?
