+1 for bookie format command. Also is it reasonable to expose one client API for format?
Because infuture we may get the requirement like when we format the NN, we also should be able to format BK storage. Currently we don't have the format API for Journal namager. That is the current limitation in NN. Currently it will format only 'file' based storage dirs. We have the plans to implement format for all kind of JornalManager. So, we may add format API for JournalManager interface. So, all JournalManager implementation classes should provide the respective implementation for format of their storage. BKJM can make use of the format API from BK and format it.

Then the admin would just have to run bookkeeper-server/bin/bookkeeper bookie -format on each machine. -Ivan On Thu, Jun 14, 2012 at 08:13:46AM +0000, Rakesh R wrote: > Hi All, > > As per my understanding, bookkeeper doesn't have the logic to pre-create the > following items and the operators need to manually create all these items > before starting the bookkeeper.
