Hi Linus, FWIW, I've been working with Andreas on this and have tested it quite extensively, although only with gfs2. I've tested it with numerous scenarios, both stand-alone (xfstests as well as several other test programs I have in my collection) and in a cluster with some very heavy duty cluster coherency tests. My testing is nearly complete, but not quite. Regards, Bob Peterson GFS2 File System
