Comment 47 for bug 49052

Its reasonably stable only journaling aspects are different from mainline. Also I have attempted to fix problems with drivers bigger than four TB the would result in corruption of the file system. The fix came from an a proposal the upstream mailing list a while back not sure where things went from there. Run apple's disk utility after using either feature. In the case of large drives it should never find issues. For journaling the results should be similar to what you get when OS X replays the journal. I have it use on my machine.
