hi,<br>
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.<br>

<p>This feature provides a way of preventing split-brains in
time.
</p>
<h2> <span class="mw-headline" id="Summary"> Summary </span></h2>
<p>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.
</p>
<p>Note: Split-brains due to network-partition can still
happen. </p>
