Issues with large LVM's ?

I've been following this list for a while now. running LVM on home systems and smaller production systems.

But now I'm about to deploy LVM on a slightly larger scale.

I'm currently planning to merge three storage systems.

-Eon Store A16U-G2421 (1.6TB)
-StorCase DS560 (1.5TB)
-SGI TP9100 (1.4TB)

Still waiting for confirmation on the usability of the TP9100 on linux thou, so it's more of a wish that a fact :)

From past experience I'm leaning toward reiserfs, but I'm looking for advice from people that have been playing with large filesystems and LVM

So..Am I courting disaster here ? :)
