Log: Synchronize unclean mirrors before adding them to a running gmirror. During gmirror startup, if component mirrors are found to be dirty as is typical after a system crash, the mirrors are synchronized to the mirror with highest priority. However if a gmirror starts without all of its mirrors present, for example because of some transient delays during tasting, the remaining mirrors must be synchronized before they may become active.
