[ovirt-users] remove a lost gluster based datacenter

[Kanagaraj Mayilsamy]

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
