SubjectMultiterabyte Filesystem Support in 2.4.x on IA64?

I don't know why you want large block device support in 2.4, but it's
now available at http://www.gelato.unsw.edu.au/patches for IA64
against Bjorn's latest tree.

I haven't tried LVM, but MD with megaraid works on a 4-way Itanium.

JFS doesn't currently work; XFS should but I've only tried ext[23],
reiserfs (both of which work) and JFS (which doesn't).

You'll be limited to 16TB for ext2, and a maximum 2TB file size; XFS
is a better bet, but is not in the core kernel.
