Hi,<br>
<br>
My POC environment have 2 hosts - host A and host B, both are CentOS7. <br>
Installed oVirt 3.6 self-hosted engine. I manually created a 2-brick <br>
GlusterFS volume using both hosts and added it to my datacenter.<br>
<br>
I tried shutting down host A. The hosted-engine restarted in host B <br>
within 3 minutes, which is very cool. However, the GlusterFS data <br>
domain, which I set both 'Use Host' and 'Path' to the host A, is down <br>
along with it.<br>
<br>
Here comes my questions:<br>
1. How can I enable failover GlusterFS data domain?<br>
2. How can I reverse back to the state before adding the data domain? <br>
The data domain is super persistent - I can't edit or delete it. I put <br>
it to maintenance mode but still unable to detach or destroy it because <br>
it requires me to remove the datacenter first. I tried but can't remove <br>
the datacenter either.<br>
3. Why can't I add another GlusterFS data domain? When I choose <br>
'GlusterFS' as my 'Storage Type' every text field become grayed-out.<br>
4. When host A restarted again, I notice that 'Use Host' was changed <br>
from host A to host B instead. Is this an expected behavior?<br>
<br>
