--_000_DB6P190MB0280702A6DFA6B66D39F816CC8B50DB6P190MB0280EURP_ Content-Type: text/plain; charset="iso-8859-1" Content-Transfer-Encoding: quoted-printable Sorry Erekle, I am just a beginner...
From the hosted engine I can put the two other servers, that are not hostin= g the hosted-engine, on maintenance, and that was what I did. When I tried = to put the last one on maintenance it did not allow me due to the hosted-en= gine and I force it shunting down from the ssh CLI.
So, what should I do? My guess is that I should ssh to the hosted engine an= d shut it down. As it would not have another node to re-launch itself, then= it would stay down. After this I should shutdown the oVirt node. Is it? Anyway, I made a mistake and I forced it. When I try to bring the cluster b= ack, I noticed that glusterd was not enabled to start when the node power-o= n. As I am a beginner, I "think" that there must be a reason to not start g= lusterd when the node comes up. So I started glusterd on the arbitrator (3r= d server), then on the second node and finally on the host that was hosting= the hosted-engine. It worked, but when I try to change the maintenance mod= e on the two nodes (2nd and 3rd) back to normal, the hosted-engine went dow= n and I had to start it manually. All this said, I would like to know how to bring the cluster down and how t= o bring it back on in the "right way" so I don't get problems. And yes, no = VM is running but the hosted-engine. Thanks for sharing your knowledge.

Third if all machines are in maintenance mode, you can start shutting down = them. If you have hosted engine setup follow this [1] Cheers Erekle [1] https://github.com/rharmonson/richtech/wiki/OSVDC-Series:-oVirt-3.6-Clu= ster-Shutdown-and-Startup [https://avatars1.githubusercontent.com/u/7966126?v=3D4&s=3D400]<https://gi= thub.com/rharmonson/richtech/wiki/OSVDC-Series:-oVirt-3.6-Cluster-Shutdown-= and-Startup> OSVDC Series: oVirt 3.6 Cluster Shutdown and Startup ...<https://github.com= /rharmonson/richtech/wiki/OSVDC-Series:-oVirt-3.6-Cluster-Shutdown-and-Star= tup> github.com Contribute to richtech development by creating an account on GitHub.
