Then, just ensure that the glusterd.service is enabled on all hosts and leave it as it
is.
If it worries you, you will have to move one of the hosts in another cluster (probably a
new one) and slowly migrate the VMs from the old to the new one.Yet, if you use only 3
hosts that can put your VMs in risk (new cluster having a single host could lead to
downtimes).
To be honest, I wouldn't change DB if it's a productive cluster. If you decide to
go that one -> make an engine backup before that.

setting single host to maintenance didn't change state of the gluster
services checkbox in cluster settings.
If not, try to 'reinstall' (UI, Hosts, Installation,
Reinstall) the
host. During the setup, it should give you to update if the host can run
the HE and it should allow you to select the checkmark for Gluster.
well, in my oVirt install there is no way to setup glusterfs services
during host reinstall. There are only choices to configure firewall,
activate host after install, reboot host after install and
deploy/undeploy hosted engine...
I think that gluster related stuff is installed automatically as it is
configured on cluster level (where in my case are gluster services
disabled).
Let's work with a single node before being so drastic and
outage-ing a
cluster.

well, it worked :-) Now all bricks are in UP state. In fact from
commandline point of view all volumes were active and all bricks up all
the time.

which host do you mean? If all hosts in the cluster I have to plan an
outage... will try...
Thanks,
