And one more test. Every time you hit the error, it causes a log replay on the next mount since the fs has shut down. Can you try # mount; umount; mount; test so that you start the test from a clean mount, and see if you still hit it? Maybe save that image off before you do that test just in case it changes the state. -Eric _______________________________________________ xfs mailing list xfs@xxxxxxxxxxx http://oss.sgi.com/mailman/listinfo/xfs
