[ovirt-users] Re: How to debug "Non Operational" host

In the host's section of webadmin does it indicate any gluster issues? sometimes it detects these and gives you the option to restart gluster in the general tab of the host. Also, on any of the hosts to check all the gluster nodes are connected you can run "gluster volume heal vmstore info summary" then you can manually restart the glusterd service. e.g. "systemctl restart glusterd.service" Regards, Paul S.

Hi Paul. I've updated the /etc/hosts file on the engine and restarted the hosted-engine. It seems that the "Could not associate brick" errors have stopped. Thank you! No change in my issue though ☹️. It looks like Glusterd is starting up OK. I did force start the bricks on ovirt1.

The hosted-engine is not on the same network at all and can not ping the IP's associated with those cards. Are you saying that it needs access to that network, or that is needs to be able to resolve the IP's. I can add them to the /etc/hosts file on the ovirt-engine or do I need to reconfigure my setup?
