[ovirt-users] Hosted engine vs. hypervisor hosts naming on hyperconverged setup

[Will Dennis]

The uncompressed engine log for the period in question is 12M... Too large for a pastebin...

However, I grepped for ‘domain’ and that culls it down to 18 lines; the results are at: http://ur1.ca/od26u

Think I found the issue… Something caused the glusterd service on ovirt-host-03 to segfault… Restarted it, and then went ahead and configured a GlusterFS storage domain for Data, which worked, and now the DC status is “Up"… Funny thing is, I do not see the “hosted_storage” domain anywhere now, just the Data SD that I created (name = vm_storage_1)

There is still nothing showing up in the “VMs” node…


Please share the /var/log/ovirt-engine/engine.log from the engine machine
If you are running 3.6.1 you should see the domain imported automatically.

Did a bit of RTFM this evening, and read in the Admin Guide that:
"The new data center is added to the virtualization environment. It will remain Uninitialized until a cluster, host, and storage domain are configured for it; use Guide Me to configure these entities."

So, in webadmin I clicked on the Data Centers node, and then clicked on the “Guide Me” link; sure enough, in the “There are still unconfigured entities:” section, there was a link for “Attach Storage”. When I clicked on it, I saw that there was an option to attach the “hosted_storage” storage domain; when I tried to do so, it failed, and I got the following events at the bottom of the webadmin UI:

Dec 27, 2015 8:58:18 PM  VDSM ovirt-node-03 command failed: Cannot acquire host id: (u'e89b6e64-bd7d-4846-b970-9af32a3295ee', SanlockException(22, 'Sanlock lockspace add failure', 'Invalid argument'))

Dec 27, 2015 8:58:18 PM  Failed to attach Storage Domains to Data Center Default. (User: admin at internal)

Dec 27, 2015 8:58:18 PM  Failed to attach Storage Domain hosted_storage to Data Center Default. (User: admin at internal)

So, how to fix this latest issue?

I clicked on the “Data Centers” node on the left nav of webadmin, and I see that the “Default” DC (the only one I have) has a status of “Uninitialized”… Not sure how to initialize it (there’s no menu option for that on the node…)
