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(1M) 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(5) for the description of the behavior of fsirand when encountering files greater than or equal to 2 Gbyte ( 2**31 bytes).

If inodes need to be 3-4 times greater than fd.file-max. Can you modify the current inode in the filesystem? Can you modify it on the fly? Or only in the creation of FS.
I'm using redhat ent 4.
Thank you for any comment you may add. (1 Reply)

I don't know what to try next, please help.
