   @sijie That make sense, I understand what you mean, but my concern is:
   
   Even if we persist the bookie status on disk, when we set the bookie to read 
only through http endpoint, the bookie will still be transitioned back to 
writable very quickly, because the DiskChecker runs periodically and would do 
the transition on each check, so there's no point setting the bookie to 
readonly on the fly, because the status still can't be persisted.
   
   I think we probably need a http endpoint that can set the bookie to 
forceReadOnly mode or cancel the forceReadOnly mode, so that we can choose to 
ignore any further transition operation. In order to do that, we need to 
persist this forceReadOnly option on disk, so that when the bookie get 
restarted, it should start with --readonly option.
