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
OK, so you are renaming logical volumes *outside* of oVirt.
The node UI is *not* part of oVirt. This is just like running:
# lvrename ...
In the shell.
I think this is one of the issues caused by not having lvm filter in the host.
With a proper lvm filter, the node UI will not be able to access the
logical volumes
used by oVirt, that should be managed only by oVirt.
Please try this:
1. Open a rootshell in the node (using ssh or node UI)
2. Create lvm filter:
vdsm-tool config-lvm-filter
Answer "yes" when the tool asks to confirm.
3. Go to the node UI - you should not be able to see or modify logical volumes
managed by oVit.
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?
