fsadm.sh:

        if detect_mounted ; then
                verbose "Skipping filesystem check for device \"$VOLUME\" as 
the filesystem is mounted on $MOUNTED";
                cleanup 3
        fi

...
cleanup() {
...
        exit ${1:-1}
}

the script exits with error "3" meaning, well, "3," I guess, when the fs is 
mounted.  Not the nicest error reporting IMHO :)
