There will be no 8TB limit for new ZFS-based filesystems, available when Lustre 1.8 ships (planned for July '08). For ext3 filesystems, the 8TB limit will be removed once the upstream kernel also removes this limit. For RHEL5 I believe they are working on up to 16TB per ext3 filesystem, but it isn't done yet, nor have we tested it. For ext4 based file system code (available from about Linux 2.6.22 and on) the 8TB limit was also removed, but we need to port our ldiskfs patches over to be ext4 based.
