  A file on an EFS filesystem can be only 2G in size. The filesystem can
  be no more than 8G in size, whether or not it is on a logical volume.
  A physical or logical volume can be larger than 8G, but not usefully
  so: mkfs still can't make a filesystem larger than 8G on it. (Each
  block (512 bytes) has a unique number which must fit into 24 bits; 512
  * 2^24 = 8G. See also inode(4).)

  Note that 'fx' had a bug in versions of IRIX before 4.0.5H which
  prevented it from *exercising* disks larger than 2G, but other 'fx'
  functions and other parts of IRIX have no trouble with disks
  (filesystems) up to 8G.

  Files and filesystems on SGI's new XFS filesystem can be 1 terabyte
  (1K gigabytes) in size. On 64-bit machines running IRIX 6.2, a file
  will be able to be 9 exabytes (9 gigagigabytes) in size and a
  filesystem will be able to be 18 exabytes in size.  See the misc FAQ
  under "WWW pages" for a pointer to a demonstration.
