Hi Sandro,

Thanks so much for the reply.

Yeah I ended up reinstalling the Engine referencing the FQDN in the storage path.  Fixed all the issues.

Thanks a lot for the Hyperconverged link- at first glance it almost looks like the exact setup I am creating and might suit our needs exactly.

Thanks!

Hi!

Question hopefully someone can help me out with:

In my Self Hosted Engine environment, the local storage domain DATA (NFS) that was created with the self engine installation has been configured as localhost:/shares


So it seems you're trying to do an Hyperconverged setup on local NFS. Please note this is not a supported configuration.
If you need to have the storage on the hosts you use for running Self Hosted Engine and other VMs, I would suggest to follow https://ovirt.org/documentation/gluster-hyperconverged/Gluster_Hyperconverged_Guide/



I suspect this is preventing me from adding any additional hosts to the oVirt Datacenter as I am receiving a VDSM error that I cannot mount that domain.  I think since the domain is set as localhost it cannot be resolved correct by any additional hosts...?

You are correct, being the NFS export referenced as localhost:// it is not accessible by other hosts.


 The ISO, Data(Master) and EXPORT domains are set as FQDN:/shares/iso and I am not seeing problems specific to them.

I am curious what the correct procedure is to change this hosted engine storage domain path from localhost:/shares to FQDN:/shares ?  I have attempted this:

1) Put hosted engine in Global Maintenance Mode
2) Shutdown hosted engine
3) edit the /etc/ovirt-hosted-engine/hosted-engine.conf file file and change:
storage=10.0.0.223:/shares   to
storage=menmaster.traindemo.local:/shares
4) Restart hosted engine


If this is a fresh install, I would suggest to restart from scratch following the Hyperconverged guide.


Although I’m not having any luck restarting the hosted engine after and running a journalctl -u on the overt-ha-agent service is giving me this:

Any thoughts?  I can attach more logs tomorrow or provide further information if needed.
