[Users] Gluster question

[Andrew Lau]

There was another recent post about this but a sum up was:

You must have power fencing to support VM HA otherwise they'll be an issue
with the engine not knowing whether the VM is still running and not bring
it up on a new host to avoid data corruption. Also make sure you have your
quorum setup properly based on your replication scenario so you can
withstand 1 host being lost.

I don't believe they'll "keep running" in a sense because of the host being
lost, but they would restart on another host. At least that's what I've
noticed in my case.
