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).
