[linux-lvm] UUID fixer released!



To help ease the problems people have had transistioning from early 0.9
versions of LVM, I wrote a little program that fixes the missing or
corrupted UUID problem.  You can find it at
ftp://ftp.sistina.com/pub/LVM/contrib/uuid_fixer-0.3-IOP10.tar.gz

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
                          UUID FIXER v0.3
                        For LVM 0.9x (IOP 10)
                    AJ Lewis <lewis sistina com>

This is a simple LVM utility to ease the problems people see with the LVM
driver in the Linux 2.4.x kernels (Up to 2.4.5 at this point).  After
extending a VG, folks have been known to have 'vgscan' no longer find their
VGs.  This is due to the fact that the UUID list (The list of numbers that
uniquely identifies each PV) in the VG gets messed up.  Previous to this
program, users had to go through a complex process with 'dd' and a hexeditor
to restore this list.

To use it, simply type 'uuid_fixer <PVS>' where PVS are the physical volumes
from a Volume Group.  You must type all of the PVs for the VG, and no more.
uuid_fixer will complain and exit if you do not.

This package contains a statically linked x86 binary, as well as the C code
for the program itself.  The makefile can be tweaked to point to your LVM
source code if you wish to compile it yourself, or you can drop uuid_fixer.c
into the LVM tools directory and just run 'make'.

Please let me know if you have issues with it.
