Well, it would be nice to say that UFS doesn't need defragmentation, but it's not quite true. In practice, though, it's much less of a problem than with Microsoft. And unfortunately we currently don't have a defragmenter. >> I just read the other day that under UFS you cannot >> resize a partition. Your supposed to get it right >> the first time out.

It is possible to increase the size of a UFS file system, but not to reduce it. We currently don't have a tool for this, either, but I'm planning to look at it Real Soon Now.
