> If a ledger is open and empty, when a bookie in the ensemble crashes no
> recovery will take place (because there's nothing to recover). This open
> empty unrepaired ledger can persist for a long time. If it loses another
> bookie, it can lose quorum. At this point it's impossible for the bookie to
> know that its an empty ledger, and the admin gets notified of missing data.
