After reading in the kernel changelog that 2.6.19 should support ext3
filesystems up to 16TB in size, I tried to create an 11TB filesystem.
Attempting to do so gets this error from mke2fs:
# mke2fs -j -J size=400 -O sparse_super,dir_index -i32768 -m1 /dev/sda4
mke2fs 1.39 (29-May-2006)
mke2fs: Filesystem too large. No more than 2**31-1 blocks
(8TB using a blocksize of 4k) are currently supported.
# mke2fs -j /dev/sda4
mke2fs 1.39 (29-May-2006)

This is on a system running 2.6.19-gentoo-r5 with sys-fs/e2fsprogs-1.39
ChangeLog for in kernel 16TB ext3 support:

Release notes for e2fsprogs claiming 16TB support (2**32 blocks).

Any idea what I am missing?

You know, I've been watching this thread thinking something was nagging
me about this. And after a night of not thinking about it I remember
what it was. I had a similar issue last summer. The way I fixed it was
to use LVM. Create a volume group the size you want and create the
filesystem inside it. My volume was only slightly larger than 8TB, but
it did create and it works great.
