HCI Disaster Recovery
Hey folks, - theoretical question, no live data in jeopardy - Let's say a 3-way HCI cluster is up and running, with engine running, all is well. The setup was done via gui, including gluster. Now I would kill a host, poweroff & disk wipe. Simulating a full node failure. The remaining nodes should keep running on (3 copy sync, no arbiter), vms keep running or will be restarted. I would reinstall using the ovirt node installer on the "failed" node. This would net me with a completely empty, no-gluster setup. What is the oVirt way to recover from this point onward? Thanks for your continued support! <3 -Christian. -- with kind regards, mit freundlichen Gruessen, Christian Reiss
Hey, is there really no ovirt native way to restore a single host and bring it back into the cluster? -Chris. On 07.01.2020 09:54, Christian Reiss wrote:

I'm not sure if all can be done from gui. I would manually configure gluster and do the host install from gui.
