Of course, this makes only sense if we *have* a DB, otherwise shutting down is probably our own option This would need to happen on all partitions, though, otherwise you have the problem of the minor partitions updating the database, and the primary partition then reading stale data from it's cache. Ceasing caching on all partitions is a problem though, as it's not clear how the primary partition distinguishes the cluster split from normal operation.
