[ovirt-users] Remove Master Data Domain in oVirt 3.5.0

Unfortunately the new Master Data Domain remained Active only for a few minutes and then the following error was thrown (as it can be seen in the Events tab):
"Failed to Reconstruct Master Domain for Data Center "
Afterwards all the other Data Domains became Inactive and the whole Data Center switched to Non Responsive Status.
I then tried to activate the Master Data Domain without success.
Finally I tried to "Re-Initialize Data Center" but there was no Data Domain available to become Master so now I can't find a way to Activate the Data Center.
Fortunately none of the VMs was affected.
What can I do now to re-activate the Data Center?

Sorry I misunderstood it. I dectivated the current Master Domain and the new one was automatically configured so all good!
Thanks a lot!
