Can you try again with -P? If that fails can you try again with -P -o bhashsize=1024 ? (or so; 1024 is the default, you could double it again if it still hangs) You might also attach gdb and see where it is. If increasing the bhashsize fixes it then I probably know what the bug is (though not yet the solution...) If you want to provide an xfs_metadump image of it from before you repair it, I could test any eventual fix against that. thanks, -Eric _______________________________________________ xfs mailing list xfs@oss.sgi.com http://oss.sgi.com/mailman/listinfo/xfs
