Looks like the cluster has both virt and gluster services enabled. Otherwise a host part of gluster-cluster cannot be a SPM. I am not sure about the standard procedure to removed a SPM host. Once SPM is disabled, you should be able to remove all the gluster hosts forcefully. Thanks, Kanagaraj ----- Original Message -----

Tibor,
This is not an officially supported solution, but I had a similar issue myself at some point (virtual gluster hosts that I was silly enough to delete without first stopping the volumes). Basically the status of the volumes is stored in the gluster_volumes table, status column. If you manually update the status to be 'DOWN' instead of 'UP' for the volumes that are giving you trouble. Then in the UI they will be down as well. At which point you should be able to properly remove them from the UI using the UI.
Once that is done you should be able to simply remove the offending hosts as there are no longer any gluster volumes associated with it.
I am sure there is a much better way of doing this (maybe REST api?), but I couldn't find it (I am not a gluster expert).

Hi,
I have try it before wrote this mail. It is impossible, it is a spm host
Error while executing action: Cannot switch Host to Maintenance mode. Host is Storage Pool Manager and is in Non Responsive state. - If power management is configured, engine will try to fence the host automatically. - Otherwise, either bring the node back up, or release the SPM resource. To do so, verify that the node is really down by right clicking on the host and confirm that the node was shutdown manually.
When I want to switch to maintence a non-spm host:
Error while executing action:
gluster4: Cannot remove Host. Server having Gluster volume.
When I want to remove an gluster brick:
Error while executing action: Cannot stop Gluster Volume. No up server found in glusters.
When I want to remove a VM that was on this gluster based datacenter:
Error while executing action:
F19glusters: Cannot remove VM: Storage Domain cannot be accessed. -Please check that at least one Host is operational and Data Center state is up.
So it is an vicious circle

Dear listmembers,
I have created a test environment for ovirt via four pc and a server.
I have two datacenter on the main server:
- a local datacenter on the server
- a gluster based datacenter by the four dekstop pc
2 weeks ago someone took my pc-s (for doing other things:)
I am could not remove the "dead" gluster based datacenter from ovirt.
- It always want to your own servers:)
- The force option doesn't work in this case.
- The gluster bricks are does not uninstallable.
- the cluster not removable
- Everything want to everything else:)
Move all the gluster hosts to maintenance. And then select all of them and click 'Remove', then select the 'Force' checkbox and Ok.
I don't want to reinstall the whole ovirt because I have a lot of vm on the local datacenter.
So, how can I remove a complety dead datacenter from ovirt?
Thanks in advance.
Tibor
