If it's a UFS, and you're running a new enough kernel, it's getting done. Of course, it can only be smart about stuff written to the disk after you built the new kernel. If your disk is mostly empty, you're cool. If it's pretty full you should back it up, delete everything (newfs is the fastest way) and then restore all your data. Most easily done by temporarily adding an additional drive big enough to hold all your stuff, and booting a fixit disk. -crl -- Chad R.
