Strange..now it's working :? I've added successfully a fourth server to the cluster without touching anything, a part migrating the HE vm to another host. But now it seems that 2 of the hosts are not recognized as working. When I try to migrate the HostedEngine to another machine I get: The host hosted_engine_1 did not satisfy internal filter HA because it is not a Hosted Engine host. The host hosted_engine_3 did not satisfy internal filter HA because it is not a Hosted Engine host. hosted_engine_2 is in maintanaince mode right now and 4 is the one that is running the VM. The VM was first migrated from 1 to 2, then from 2 it started giving those errors, then I successfully added 4 and I could migrate the VM to it, and now it is stuck there. I'm trying to look through the VDMS logs but oh boy, they are so verbose!

All from the CLI. Right now in the GUI I have the "Reinstall" button greyed out. What's happening?

How can I forcefully migrate the engine VM?

Trying to set the maintenance gives me: [root@vm01 ~]# hosted-engine --set-maintenance --mode=global /usr/lib/python2.7/site-packages/ovirt_hosted_engine_ha/lib/storage_backends.py:15: DeprecationWarning: vdscli uses xmlrpc. since ovirt 3.6 xmlrpc is deprecated, please use vdsm.jsonrpcvdscli import vdsm.vdscli it's not vey clear if it worked and it's just a warning or since it's deprecated it didn't work at all

Ok, HE moved to host1...now, sorry for being so silly but, how do I remove a host from ovirt-engine GUI? "Remove" (just as reinstall) is greyed out too
