The DC storage master domain is on a (unrecoverable) storage on a
remote dead
host.
Engine is automatically setting another storage as the "Data (Master)".
Seconds later, the unrecoverable storage is marked as "Data (Master)" again.
There is no way to start the Datacenter.
Both storages are gluster. The old (unrecoverable) one worked fine as a
master.
This may be related to this bug:
https://bugzilla.redhat.com/1183977.
Are you using latest engine?
Any hint?
If a one gluster node dies, and this brings down your data center,
your gluster is probably not set up correctly. With proper replication
everything should work after a storage node dies.
