In the event that a replace-brick operation fails midway through for whatever reason, power failure, or a bug that causes the inode table to be walked to the end of time requiring the process to be killed, you should be able to restart the process by issuing the replace-brick..start command again. It should also restart the process automatically when glusterd is started.
Joe, we will try to address this, meantime, any thoughts on http://lists.gnu.org/archive/html/gluster-devel/2012-10/msg00050.html ?
