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 afterwards.

OPTIONS

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