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 bricks are showing all green at least in the UI, but they never seem to catch up and
not show any unsynced entries:
As for mounting the bricks, they are mounting based on what is in /etc/fstab.

What does this "extra" mount?

I've noticed that on my working servers, I see this output:
[root(a)ovirt2.dgi ~]# mount | grep storage
ovirt1-storage.dgi:/engine on /rhev/data-center/mnt/glusterSD/ovirt1-storage.dgi:_engine

type fuse.glusterfs
(rw,relatime,user_id=0,group_id=0,default_permissions,allow_other,max_read=131072)
There is obviously something not mounting properly on ovirt1. I don't see how this can
be a network issue as the storage for the hosted engine is working ok.
I truly appreciate the help. Any other ideas or logs/places to check?
Cheers,
Gervais

Hi Gervais,
The engine doesn't need to be able to ping the IP address, just needs
to know what it is so adding them to the /etc/hosts file should work.
Also, I would check ovirt1, is it mounting the brick, what does "systemctl status
glusterd" show, what are the logs in /var/log/gluster ?

Paul S.

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
