Hi Will, 

Which oVirt version are you using? (rpm -q ovirt-engine) 
Is the GlusterFS storage domain the master? 
Also, please provide: 

- /var/log/ovirt-engine/engine.log 
- /var/log/vdsm/vdsm.log from both nodes 
- /var/log/gluster/* 

And the output of 'rpm -q glusterfs' from both hosts. 


Thanks, 
Elad

Hi all, 

Yes, I got this failed to active master storage domain issue. I'm sort of not sure where to start after a few attempts and many google results. Is a good lead on how to troubleshoot this master storage failed to start issue? 

I have a 2 node ovirt setup. It is a simple setup with GlusterFS with one volume only. Both nodes were put to "maintenance mode" before reboot. After reboot, I checked the followings were all up: 
vdsmd, ovirt-engine, ovirt-websocket-proxy, nfs, nfslock, glusterd, glusterfsd 

I can reach to both nodes and I can activate them in overt. however, the master storage can't be activated. 

I tried to start with just node1. It worked fine and storage domain was up. But once I booted up and activated node2, the NFS export domain just fails followed by the Master domain failure. 

Any suggestion where to start? 

Will
