Hi Karli,

Correct me if I'm wrong, but I think that your statement is true *if*
the networks are set as mandatory, which is not automatically wanted nor
true. In our case, we have to disable this mandatory attribute.

Correct. I took a hasty look at the logical networks page[*] and didn't see any mention of it and thought they must've removed that option.

Can you still do that? Doesn't make much sense to me, purposely having non-operational/unavailable hosts in a cluster due to network incompatibility...

I agree that when the networks are mandatory, every host unable to use
them will end up unavailable.
