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(8) 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(7) for the description of the behavior of fsirand when
encountering files greater than or equal to 2 Gbyte ( 2^31 bytes).
