Hi Paul,

I don't quite get what you mean by this:

assuming you have a storage network for the gluster nodes the engine needs to resolve be able to resolve the host addresses

The storage network is on 10GB network cards and plugged into a stand-alone switch. 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? It was working as it currently configured before applying the update.

I have no idea why the ovirt1 server is not showing up with the fqdn. I set up all the servers the same way. It's been like that since I set things up. I have looked for where this might be corrected, but can't find it. Ideas?

The yellow bricks... I can force start them (and I have in the past), but now it turns green for a few minutes and then returns to red.

Cheers,
Gervais

Hello Gervais,

           is the brick mounted on ovirt1 ?  can you mount it using the settings in /etc/fstab ?

The hostname is not using a FQDN for ovirt1

assuming you have a storage network for the gluster nodes the engine needs to resolve be able to resolve the host addresses
ovirt1-storage.dgi
ovirt2-storage.dgi
ovirt3-storage.dgi

So that it can assign them to the correct network.

When the volume is showing yellow you can force restart them again from the GUI.

Regards,

Paul S.

Hi Vojta,

Thanks for the help.

I tried to activate my server this morning and captured the logs from vdsm.log and engine.log. They are attached.

Something went awry with my gluster (I think) as it is showing that the bricks on the affected server (ovirt1) are not mounted:

The networking looks fine.
