Re: [ovirt-users] Unable to import pre-configured nfs data domain
I'd be happy to, but how/where do I do that?

Re: [ovirt-users] Unable to import pre-configured nfs data domain
Thank you! That does do some interesting things, but doesn't appear to work. I've added a new storage domain, merged the differences in the metadata file back to the old one and powered it up. When I start up the nodes they endlessly report: VDSM ovirt-reqa1 command failed: (-226, 'Unable to read resource owners', 'Sanlock exception') I tried reinstalling one of them and the error message continues. At least for now I've restored the old config and the error is gone.

It's supported only in case the master domain was previously correctly detached from the data center. In case of an unexpected complete disaster, when a fresh engine is installed and used, it's still possible to recover the master domain in theory. You must find `metadata' file in the master domain and edit it for the new engine. It's completely unsupported and it may or may not work.

Re: [ovirt-users] Unable to import pre-configured nfs data domain
Am I correct in the assumption that importing a previously master data domain into a fresh engine without a current master domain is supported?

[ovirt-users] Unable to import pre-configured nfs data domain
We are currently evaluating ovirt for our new VM backend and part of that is moving the engine to a physical controller node. So I took the opportunity to test a DR scenario where the engine fails and takes more than a reboot to bring it back up. For the most part it was straight forward to get it up and going, but I'm having a hard time getting the previous master data domain to import into the new engine. I've attached relevant snippets of the engine and vdsm log.
