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. 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."

Subject: [Users] Removing orphaned hosts
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."
