Name

fsirand − install random inode generation numbers

Syntax

fsirand [ −p ] special

Description

The fsirand command installs random inode generation numbers on all the inodes on device special.  This helps increase the security of file systems exported by NFS. 

The fsirand command must be used only on an unmounted file system that has been checked with fsck(.). The only exception is that it can be used on the root file system in single-user mode, if the system is then immediately rebooted.

Options

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