Features/outcast

  Feature 
This feature provides a way of preventing split-brains in time.

  Summary 
At the moment there is no way of marking a brick as stale copy, 
because of this if a file is modified when the source brick is down the 
file goes into split-brain. This feature should give the functionality 
where a file can be marked as outcast. Modifications on the file are 
considered to be successful only if it succeeds on at least one good 
copy. If the operation succeeds only on outcast files then the operation
 is treated as failure.
Note: Split-brains due to network-partition can still happen.?

hi,
     I am one of the people responsible for this feature. The feature is 
still in design phase. Nothing concrete yet. I will send out a mail once 
we are certain of the design.
