------5YHBUFYRT5GVBTR0JVW5A916EMFQ77 Content-Transfer-Encoding: 8bit Content-Type: text/plain; charset=UTF-8 Hi, My POC environment have 2 hosts - host A and host B, both are CentOS7. Installed oVirt 3.6 self-hosted engine. I manually created a 2-brick GlusterFS volume using both hosts and added it to my datacenter. I tried shutting down host A. The hosted-engine restarted in host B within 3 minutes, which is very cool. However, the GlusterFS data domain, which I set both 'Use Host' and 'Path' to the host A, is down along with it. Here comes my questions: 1. How can I enable failover GlusterFS data domain? 2. How can I reverse back to the state before adding the data domain? The data domain is super persistent - I can't edit or delete it. I put it to maintenance mode but still unable to detach or destroy it because it requires me to remove the datacenter first. I tried but can't remove the datacenter either. 3. Why can't I add another GlusterFS data domain? When I choose 'GlusterFS' as my 'Storage Type' every text field become grayed-out. 4. When host A restarted again, I notice that 'Use Host' was changed from host A to host B instead. Is this an expected behavior? Regards, Wee Sritippho P.S: Please excuse my poor English. ------5YHBUFYRT5GVBTR0JVW5A916EMFQ77 Content-Type: text/html; charset=utf-8 Content-Transfer-Encoding: 8bit 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.
