[ovirt-users] Master storage domain no longer exists, how to recover?

[Steve Dainard]

And 5 minutes later I found...

https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Virtualization/3.4/html-single/Administration_Guide/index.html
3.5.6. Re-Initializing a Data Center: Recovery Procedure

Which worked quite well.
