Is this something the OS takes care of or is > there a utility I can use to degrag the volume? This question doesn't belong on FreeBSD-net; there is nothing network-related here. However, I'm a nice guy and will answer your question anyway. The answer is no. The filesystem is set up to automatically defragment files as they are extended, and in any case even fairly high levels of fragmentation do not have a large impact on everyday filesystem performance. (There are certain access patterns which can cause problems, however.) -GAWollman -- Garrett A.
