NAME
      fsirand - install random inode generation numbers
 


SYNOPSIS
      fsirand [ -p ]  special
 


DESCRIPTION
      fsirand installs random inode generation numbers on all  the
      inodes on device special, and also installs a file system ID
      in the superblock. This helps increase the security of  file
      systems exported by NFS.
 
      fsirand must be used only on an unmounted file  system  that
      has been checked with fsck(1M) The only exception is that it
      can be used on the root file system in single-user mode,  if
      the system is immediately re-booted afterwards.
 


OPTIONS
      -p    Print out the generation numbers for all  the  inodes,
            but do not change the generation numbers.
 
 USAGE
      See largefile(5) for the  description  of  the  behavior  of
      fsirand  when  encountering files greater than or equal to 2
      Gbyte ( 2**31 bytes).
