When quorum is regained (or if it's not lost) the fenced node's journal is replayed so the file system metadata should remain intact. That does not mean that data won't be lost. If the node was fenced while it had data in its cache, that data may be lost. In critical situations, you can mark files and/or directories with a flag that makes the data journaled as well, so the data should be protected. Of course, that has a performance penalty. There's a small section about this in the GFS faq.
