ok, workaround applied, glustereventsd service enabled and started on all hosts.
I can see this log entry in volume EventsDetected change in status of brick 10.0.4.11:/gluster_bricks/engine/engine of volume engine of cluster McHosting from UNKNOWN to UP via gluster event.
but Bricks tab shows still two (.12 and .13) of three bricks in Unknown state. From command line point of view all bricks are up and healthy.
it looks like engine thinks that gluster service is disabled in cluster but I cannot enable it because checkbox is disabled. In my other (FC based) oVirt instance Gluster Service checkbox is not selected but not disabled. So I am interested what could make that checkbox inactive...
For the vdsm, you can always run '/usr/libexec/vdsm/vdsmd_init_common.sh --pre-start' which is executed by the vdsmd.service before every start (ExecStartPre stanza) and see if it complains about something.
[root@ovirt-hci03 ~]# /usr/libexec/vdsm/vdsmd_init_common.sh --pre-start vdsm: Running mkdirs vdsm: Running configure_vdsm_logs vdsm: Running run_init_hooks vdsm: Running check_is_configured sanlock is configured for vdsm lvm is configured for vdsm abrt is already configured for vdsm Managed volume database is already configured Current revision of multipath.conf detected, preserving libvirt is already configured for vdsm vdsm: Running validate_configuration SUCCESS: ssl configured to true.

it looks like root of the problem is that Gluster service is
disabled in
cluster settings and cannot be enabled. But it was enabled before...
also I have to manually install vdsm-gluster when I (re)install new
host, but bricks from this host are in unknown state in admin. Maybe
vdsm-gluster is not correctly configured? Maybe glustereventsd is not
running? I am just guessing...
I have no access to other HCI installation so I cannot compare
differences.
I would be really happy if someone could tell me what circumstances
could disable Gluster service checkbox in admin and how to enable it
again...
