See the discussion in /usr/share/doc/smm/05.fastfs/paper.ascii.gz The design of ffs reduces the kind of fragmentation seen in FAT systems, so the need for a defragger is essentially eliminated. If you really accumulate fragmentation (in the DOS sense), then a dump/restore is in order. I have never found a time when this was necessary (in 6 years of administering Unix boxes using ffs or its derivatives). -- M. L. Dodson bdodson@scms.utmb.edu 409-772-2178 FAX: 409-772-1790
