There was an e2fsprogs bug in RHEL-4's initial release for filesystems >4TB; that is fixed in U1. If you're running devices larger than 2TB, you really want to upgrade to U1; it includes other fixes for things like device-mapper on large devices.
For the unfixed e2fsprogs, passing a blocksize explicitly with "mke2fs -b4096" should be a workaround for the 4TB wrap problem.
