   I understand the problem.
   Unfortunately this is quite hard to implement because the client has no knowledge of the fact that the bookie has multiple disks and also the mapping between a ledger and the disk depends on the configuration and especially the implementation of the Storage.
   For for instance a Bookie may be readonly for one ledger and not for the next ledgerid.
   
   Currently the bookie advertises its read only status, this way clients don't choose it for new ledgers (or new segments)
   
   Even by using an alternative mechanism to advertise the read only status (for instance a new error code while writing), that piece of information won't be useful for subsequent ledgers.
   
   We will have to be much creative to implement this feature
