Okay, since you asked:
(note: this is in node 4.3.10. but hosted-engine is 4.2
I'd LIKE to upgrade it. but the upgrade process is broken.
thats a whole nuther story, aobut how postgresql10 doesnt show up even though
its required for
yum update 'ovirt*setup'
:-/)
1. go to individual node UI.
2. Click on Storage
3. Look at the right-sdie aera for "Volume Groups". click on the one that is
for your master data volume
4. Click on the Rename button on the top right. Pick something sensible
5. wait a while, and eventually your cluster logs will freak out.
Happily for me, since our VMs are very lightly loaded, this did not immediately
cause a crash.
But the cluster freaked out.. engine log spewed those errors after a while..
and in the cluster(engine) UI, it eventually showed
Storage->Domains
as offline.
(well it shows the master as offline, and it didnt even know about the other
ones any more, until I renamed it back)

Did you rename the volume from within oVirt UI?
Can you give clear reproduction instructions, how to break your storage domain
by renaming a volume?
