In that case, I probably don't understand what you're trying to do.

So you want the servers to keep running as long as possible and the
clients should go down after a power outage of (say) five minutes?
That's possible too.

Sure. But if you can describe more clearly what you're trying to do,
we might come up with other alternatives as well, as I don't think
this is what you want to do.
