The default/default data center/cluster had to be abandoned because of a
split-brain that could not be healed. Can't remove old storage from
database, can't get data center up due to corrupt storage, ends up a circular
argument.
I started over with same hosts, totally new storage in new data center. This
mill/one data center/cluster was working fine with VM2 storage, then died.
