It’s definitely not starting, you’ll have to see if you can figure out why. A 
couple things to try:

- Check "virsh list" and see if it’s running, or paused for storage. (google 
"virsh saslpasswd2 
<https://www.google.com/search?client=safari&rls=en&q=virsh+saslpasswd2&ie=UTF-8&oe=UTF-8>”
 if you need to add a user to do this with, it’s per host)
-  It’s hyper converged, so check your gluster volume for healing and/or split 
brains and wait/resolve those.
- check “gluster peer status” and on each host and make sure your gluster hosts 
are all talking. I’ve seen an upgrade screwup the firewall, easy fix is to add 
a rule to allow the hosts to talk to each other on your gluster network, no 
questions asked (-j ACCEPT, no port, etc).

Good luck!
