ovirt version is 3.4.  I did have a slightly older version of vdsm on gluster0 but I have updated it and the issue persists.  The compatibility version on the storage cluster is 3.3.

I checked the logs for GlusterSyncJob notifications and there are none.

Hi Alastair,

This could be a mismatch in the hostname identified in ovirt and gluster.

You could check for any exceptions from GlusterSyncJob in engine.log.

Also, what version of ovirt are you using. And the compatibility version of your cluster?

Hi thanks for the reply. Here is an extract from a grep I ran on the vdsm log grepping for the volume name vm-store.  It seems to indicate the bricks are ONLINE.

I am uncertain how to extract meaningful information from the engine.log can you provide some guidance?

Thanks, 

Alastair

engine.log and vdsm.log?

This can mostly happen due to following reasons
- "gluster volume status vm-store" is not consistently returning the right output
- ovirt-engine is not able to identify the bricks properly

Anyway, engine.log will give better clarity.

I just did a rolling upgrade of my gluster storage cluster to the latest 3.5 bits.  This all seems to have gone smoothly and all the volumes are on line.  All volumes are replicated 1x2

The ovirt console now insists that two of my volumes , including the vm-store  volume with my vm's happily running have no bricks up.

It reports "Up but all bricks are down"

This would seem to be impossible.  Gluster  on the nodes itself reports no issues

[root@gluster1 ~]# gluster volume status vm-store

Task Status of Volume vm-store

There are no active volume tasks


As I mentioned the vms are running happily
initially the ISOs volume had the same issue.  I did a volume start and stop on the volume as it was not being activly used and that cleared up the issue in the console.  However, as I have VMs running  I can't so this for the vm-store volume.  


Any suggestions, Alastair
