A safer way is to downgrade vdsm to the previous version.

1. Put the gluster domain in maintenance
    - select the domain in the storage tab
    - in the "data center" sub tab, click maintenance
    - the domain will turn to locked, and then to maintenance mode

2. Edit the domain
3. Change the address to the same one configured in gluster (ovirt01...)
4. Activate the domain

Yes, it should keep working after an upgrade

However, using straightforward setup, like using same server address
in both ovirt and
gluster will increase the chance that things will continue to work
after an upgrade.

This is good, and makes debugging this issue easy.

Correct

The code assumes that the server address is in the list, so removing
it is correct.

This assumption is wrong, we will have to change to code to handle this case.

The traceback in the log is very important, without it would be very
hard to debug this issue.
