I have an oVirt installation with two datacenters. One datacenter called "Dev" has three nodes that are just PCs and live in a datacenter called "Development". The other is a production cluster called "DMZ" with two Dell servers and it lives in a data center called "Production". I had to bring all our servers down for some electrical maintanance in the building, so I brought down all running VMs gracefully and brought down all hosts gracefully. When I brought the servers back up, the Dev cluster came up fine, but the DMZ cluster's hosts would never go green. I could put them in maintenance mode and reinstall them, but they would still not come "UP". I worked with this for hours with no change in my situation. Finally, I made the decision to remove the datacenter and rebuild it. I force removed the Production data center.
Now here is my situation. I have two nodes in a cluster called DMZ that are not in any datacenter. I can put them in maintenance mode and reinstall them, but they never come up afterward. I can't remove either one because " Error while executing action: Cannot remove Host. Related operation is currently in progress. Please try again later." I just don't know how to get back from this.
it happened to me once, after I restarted the engine I could move hosts to maintenance mode and remove. can you please try it out?
All the VMs from this datacenter are sitting on a NAS. I tried to create another data center and import the data domain, but I realize this isn't supported, so that is one issue. When I try to just remove the DMZ cluster, it won't let me because "Error while executing action: Cannot remove default Host Cluster."
