 You can try to migrate it from the engine.
 If it doesn't work you can got to the first host,
 set the global maintenance mode with
hosted-engine --set-maintenance --mode=global
 connect to the engine VM and shutdown it
 restart the engine VM on the first host with:
hosted-engine --vm-start

 Did you added your additional hosted-engine hosts from CLI or from
 the web interface (there is special sub-panel in the add host dialog)?
 I strongly recommend the second way.

Re: [ovirt-users] Add more hosts

[Davide Ferrari]

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

 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

 I suggest to forcefully migrate the engine VM to the first host; remove
 the other hosts from the engine and redeploy from there as
 hosted-engine-hosts.

 Hello again

 as I said I'm a beginner with OVirt and I was playing with a
 proof-of-concept cluster with OVirt 4.0 + GlusterFS 3.8, following this
 guide

 http://www.ovirt.org/blog/2016/03/up-and-running-with-ovirt-3-6/

 (it works smoothly with 4.0 too)
 I've created the cluster and the engine is running as an higly
 available VM in the cluster itself with hosted-engine --deploy but now 
 I
 want to add a fourth machine to the cluster but I get this error:

  Cannot automatically add the host to cluster Default: Cannot add
 Host. There is no available server in the cluster to probe the new 
 server.

 both if I try to add an host from Ovirt AAdmin GUI or if I try to
 run "hosted-engine --deploy" on the new machine. Is it possible to have
 this cluster conf (with the engine running as a VM) with 4 or more
 machines? What thing should I have to do?

 Thanks in advance

You can try to migrate it from the engine.
If it doesn't work you can got to the first host,
set the global maintenance mode with
   hosted-engine --set-maintenance --mode=global
connect to the engine VM and shutdown it
restart the engine VM on the first host with:
   hosted-engine --vm-start

 Did you added your additional hosted-engine hosts from CLI or from the

 I strongly recommend the second way.

I suggest to forcefully migrate the engine VM to the first host; remove the
other hosts from the engine and redeploy from there as hosted-engine-hosts.

 Hello again

 as I said I'm a beginner with OVirt and I was playing with a
 proof-of-concept cluster with OVirt 4.0 + GlusterFS 3.8, following this
 guide

 http://www.ovirt.org/blog/2016/03/up-and-running-with-ovirt-3-6/

 (it works smoothly with 4.0 too)
 I've created the cluster and the engine is running as an higly
 available VM in the cluster itself with hosted-engine --deploy but now I
 want to add a fourth machine to the cluster but I get this error:

  Cannot automatically add the host to cluster Default: Cannot add Host.
 There is no available server in the cluster to probe the new server.

 both if I try to add an host from Ovirt AAdmin GUI or if I try to run
 "hosted-engine --deploy" on the new machine. Is it possible to have this
 cluster conf (with the engine running as a VM) with 4 or more machines?
 What thing should I have to do?

 Thanks in advance

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

Did you added your additional hosted-engine hosts from CLI or from the web
interface (there is special sub-panel in the add host dialog)?
I strongly recommend the second way.

[ovirt-users] Add more hosts

Hello again

I've created the cluster and the engine is running as an higly available VM
in the cluster itself with hosted-engine --deploy but now I want to add a
fourth machine to the cluster but I get this error:

There is no available server in the cluster to probe the new server.

both if I try to add an host from Ovirt AAdmin GUI or if I try to run
