If using ext{2,3,4}, I would strongly recommend *against* doing this.
Running fsck from time to time isn't a bad thing.  It can surely happen
that it finds some things which should be fixed.  If this is needed fro
xfs, I dunno.  For reiserfs it is not needed, it will take care of this
on its own - and really needed, it'll scream loudly and you won't be
able to mount that partition/lv and this fix might take hours to
complete.  Regarding other file systems, I have no experience.

Removing these fsck's is like skipping taking your car to a car check
every now and then.  You car may run for a long way without a service.
But when it is really needed, it can take a long time to fix and might
be more costly compared to if you did this regularly ... and if you want
a reliable server, having a little maintenance downtime couple of times
during a year might not be such a bad investment - in the long run.

Just my 2cents
