I need to setup a 3.27TB ext3 filesystem using -i 1024 and -b 1024.

When I try to format this partition I get the "Filesystem too large." error. Are there any plans to update these limits? are there any patches already available that I can try out? Or am I just SOL here?
The same patches that have been posted here (or maybe ext2-devel?)
to increase the fs size to 16TB are applicable in your case.

Yes; just note that with a 1k blocksize, 2^32 blocks will only get you
as far as 4TB, not 16TB.  But yes, it should work.

However, 1k blocksize is usually a bad idea unless you really need the
very very best space efficiency on the filesystem: it usually performs
worse than 4k blocksize, and it imposes other limits such as a maximum
file size of a bit over 16GB.  With 4k blocksize, a 3.27TB filesystem
should just work.

I should mention I have tried this on 2.6.14 and 2.6.8. From what I have found, it seems thees kernels should already have the 16TB file system support. Perhaps I am looking in the wrong place. Any help finding this patch would be appreciated
