If the disk isn't full, I guess it doesn't matter, but this test explicitly tests ENOSPC. Working on better understanding this path to see if I can fix it (unless Dave beats me to it ...) -Eric _______________________________________________ xfs mailing list xfs@xxxxxxxxxxx http://oss.sgi.com/mailman/listinfo/xfs
