FSIRAND(8)                  System Manager's Manual                 FSIRAND(8)



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 filesystem ID  in  the  superblock.
       This helps increase the security of filesystems exported by NFS.

       fsirand  must  be  used  only  on an unmounted filesystem that has been
       checked with fsck(8).  The only exception is that it can be used on the
       root  filesystem  in single-user mode, if the system is immediately re-
       booted afterwords.

OPTIONS
       -p     Print out the generation numbers for all the inodes, but do  not
              change the generation numbers.

SEE ALSO
