fsirand(1)              (BSD Compatibility Package)              fsirand(1)

NAME
     fsirand - install random inode generation numbers

SYNOPSIS
     /usr/ucb/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(1M). The only exception is that it can be used on
     the root filesystem in single-user mode, if the system is immediately
     re-booted afterwards.

     The -p option prints out the generation numbers for all the inodes,
     but does not change the generation numbers.

SEE ALSO
     fsck(1M).
