[ovirt-users] Host cannot connect to hosted storage domain

[Alexander Witte]

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

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...?  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

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.
