Not without ext3 patches (until the very-large-ext3 patches now pending on l-k go in), sure. But because it's LVMed you could cut it into a couple of exg3 filesystems easily. (I find it hard to imagine a single *directory* whose children contain 12Tb of files in a form that you can't cut into pieces with suitable use of bind mounts, but still, perhaps such exists.) -- `NB: Anyone suggesting that we should say "Tibibytes" instead of Terabytes there will be hunted down and brutally slain.
