[MDS safety] Certain volumes have lesser safety than expected

[JeffreyDevloo]

Certain volumes on the Nuvolat environment are only having one mds entry in their metadata backend config while their should be at a minimum of 2.

The only thing that I can think about is that the master switches and the old master is removed first from the config. Leaving only the single slave behind. The next step is normally configuring the local master with its slave but if an exception occurs, it can lead to a reduced safety.

I will continue to monitor the situation and try to find some logging evidence.
