ok, workaround applied, glustereventsd service enabled and started on
all hosts.
I can see this log entry in volume Events
Detected 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...
well, on db side it looks like cluster has gluster_service disabled...
engine=# select virt_service, gluster_service from cluster;
virt_service | gluster_service
--------------+-----------------
t | f
(1 row)
still don't know why the checkbox is disabled. Would it be safe to
enabled gluster_service directly in db? I suppose no... :-)
