XFS seems like the most obvious and maybe safest choice. FWIW, we use
it on SL5 and SL6. Ultimately any issues we've had with it turned out
to be hardware-related.

ZFS has some really nice features, and we are using it for larger
filesystems than we have XFS, but so far only on BSD rather than Linux...

It works well with being able to repair huge filesystems in reasonable amount of RAM, and handle large directories, and large files.  Unfortunately jfs doesn't appear to be supported in 6?  (or is there a repo I can add?)
