Joe seem to want one. This size is certaintly within the reach of an ISP now, and disks just keep getting bigger. My administrative bias is that partitioning for a reason other then policy should be avoided and thus I'd love to see filesystem size support keep ahead of volume sizes where possiable. That said, unless someone gives me a very substantial amount of money to build a cluster at work, I'm not going to be building any TB file systems for a few more years. -- Brooks -- Any statement of the form "X is the one, true Y" is FALSE.
