I'd be happy to, but how/where do I do that?

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.

Regards,
Logan

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.  We don't have guidelines how to do it, but you may try to create
a new master domain, then detach it and compare the two metadata files.

Am I correct in the assumption that importing a previously master data domain 
into a fresh engine without a current master domain is supported?
