FreeBSD will defragment itself without any action from the user. However, defragmentation requires some blank space, and (ideally) you should not let any partition get more than 80% full. You can check on that with "df -h": bob@sonic:~> df -h Filesystem Size Used Avail Capacity Mounted on /dev/ad0s2a 248M 68M 160M 30% / devfs 1.0K 1.0K 0B 100% /dev /dev/ad0s2g 2.4G 281M 1.9G 13% /home /dev/ad0s2e 248M 1.2M 227M 1% /tmp /dev/ad0s2f 8.7G 2.4G 5.6G 30% /usr /dev/ad0s2d 248M 17M 211M 8% /var The column labeled "Capacity" tells you the percentage of space being consumed - over 80% would be bad. Note that the "devfs" uses 100% (on FBSD 5.x, it doesn't exist on 4.x) - that's no problem, it's not a partition and it will always be 100%. regards, Robert
