If you are using SUSE, then use reiserfs.  It has ACLs and is mostly patched.

If you are using RH, then use ext3.  RH in the past has been known to have
a broken reiserfs (not known for keeping it patched).

In my performance benchmarks, I found reiserfs to be somewhere between jfs and ext3, where
ext3 was the fastest, but reiserfs doing exceptionally well on random file creates
and deletes.  Thought ext3 beats reiserfs in many of our tests, it was not by
an overwhelming margin.  We were very surprised by the lack of performance of JFS.. though
it did have the lowest CPU utilization of the 3.

We run SUSE primarily... therefore we use reiserfs (mostly with LVMs).
RH is sorta new to the LVM thing... so although we use ext3 on our RH systems,
most of them do not use LVM.  We have over 7TB of data that uses LVM with
reiserfs... we're quite pleased with the performance and capability.

We love the ability to do resize_reiserfs while the filesystem is mounted.
Constantly amazes the "Unix" purists.
