Well, Karlski, my answer would have to be 'everything.' :)
This will be a pretty general purpose server doing many different things.
Mysql is one of the things it will be doing.
Now I've handed the bulk of the array space over to LVM. That would give me
the flexibility to use more than one filesystem. Hmmm, I'll have to dig up
some mysql benchmarks, run them up the flag pole and see who salutes.

For our mysql servers we use reiserfs, which we install via a kernel rpm.
We then install reiserfs-tools rpm, and do some work on /etc/fstab and
some mount commands to get it all functioning.
We do this for performance and redundancy.
The daemons you run will likely have a say in which filesystem you plan to
deploy, good idea to post to those lists as well. e.g. "Squid performs
horrible on RAID5, and it doesn't use SMP, it likes ext3 just fine because
of how it works".
Names some daemons, you'll probably get alot of opinions from people
fairly close to their respective code-bases, or their shadowy minions ; )

Now that I've been enlightened to the terrible write performance of ext3
on my
new 3Ware RAID 5 array, I'm stuck choosing an alternative filesystem. I
benchmarked XFS, JFS, ReiserFS and ext3 and they came back in that order
from
best to worst performer.
I'm leaning towards XFS because of performance and because centosplus
makes
kernel modules available for the stock kernel.
How's the reliability of XFS? It's certainly been around long enough.
Anyone care to sway me one way or another?
