System Administration Commands                        fsirand(1M)



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).
