>
> Currently we had *Cookie* for each bookie to record the directories it used
> for ledgers. So when the admin wants to add a new disk for a bookie, we can't
> change the configuration and restart it simply. an admin command would be
> added to help admin guys adding a new disk to a bookie and upgrading its
> *Cookie*.
> Adding a brand new disk would be quite easy. But if we want to remove a disk
> or replace a disk, it isn't trivial. BOOKKEEPER-201 would take care of
> removing/replace a disk.
