We have Lustre filesystems in the 100TB range right now.  We don't exceed
the 2TB block device/filesystem limits, but rather combine multiple
filesystems to provide a large virtual volume over the network.  This means
Lustre will work just fine with 2.4 kernels also.

Mind you, some of our customers have > 2TB NFS filesystems already, but I
don't think they are served by Linux (NetApps or something).  Since NFS
doesn't have a block device it isn't limited by the 2TB size.

Cheers, Andreas
