HP-UX's vxfs (veritas i believe) ships with a defrag tool that packs
extents and reorders data based on access usage (dir order I believe).
HPUX documentation did recommend running it and tuning how often by
ammount of fragmentation. I found on a heavily used ClearCase server a
nightly run kept fragmentation down; although a weekly run was probably
all that was necessary. Haven't run HPUX in several years so things may
be different now.
