That was discussed not so long ago. But I can't remember if it washere in the mailing list or on IRC (or somewhere else). But theconclusion was that you are better of using 64 bit and XFS for suchlarge filesystems, and that you need a 64 bit system anyway for ext3/4to go over 8TB. Well, that is what I remember the conclusion to be :-)
