After some prodding by phk@ I made a test for problems seen with "newfs -b 32768 -f 4096". http://people.freebsd.org/~pho/stress/log/cons218.html I was using these watchdog options: -t 900 -e 'ls /tmp /dev /mnt > /dev/null; true' -s 60 and /mnt was the mount point for the test filesystem. -- Peter Holm
