I can't seem to find an answer to this question, and the answer I've been able to infer from other posts isn't the one I want, so I'm just going to ask it straight out.
If a dependency is set up where the parent is a group, do the children become unreachable when:
a) All parents are down
b) At least one parent is down
I want to use this in situations where I have redundancy, so I really want (a) to be the answer. From what I've read, it seems that (b) might be the answer. If that's the case, can anybody explain the logic/use case?
