LVM 0.9
Logical Volume Manager Installation                                 13/11/2000


Installing this package will create various files in /sbin, /usr/share/man/man8
and an optional shared library in /lib.

If you don't have a stock kernel including LVM or you want to use a more
recent LVM version than the one in the stock kernel you have to patch your
kernel with the corresponding patch from <ftp://ftp.sistina.com/pub/LVM/0.9/>.


1. Change to LVM/PATCHES

2. Choose the corresponding patch from here or
   <ftp://ftp.sistina.com/pub/LVM/0.9/PATCHES>
   or one of the mirrors (replace asterisks below with those of the
   corresponding patch of your choice) and patch your 2.2.17 kernel by

      cat linux-2.2.17-rawio.patch | ( cd /usr/src/linux; patch -p1)

   and either

      cat lvm-0.9-2.2.17-stock.patch | ( cd /usr/src/linux; patch -p1)
   or
      cat lvm-0.9-2.2.17-new_raid.patch | ( cd /usr/src/linux; patch -p1)

   "stock" supports Ingo Molnar's raid code in the stock 2.2.17 kernel.
   "new_raid" supports Ingo Molnar's new raid code for the 2.2.17 kernel.
   You can get it from <ftp://ftp.kernel.org/pub/linux/kernel/people/mingo/raid-patches/>
   or one of the kernel mirrors.


   In case of a 2.4.0-test10 kernel patch it by

      cat linux-2.4.0-test10-VFS-lock.patch | ( cd /usr/src/linux; patch -p1)
      cat lvm-0.9-2.4.0-test10.patch | ( cd /usr/src/linux; patch -p1)


3. cd to /usr/src/linux and configure LVM and loadable module support
   if you want to load it as a module (see /usr/src/linux/README for
   instructions) by "make config/menuconfig/xconfig" (whichever you prefer)

4. Build a new kernel

5. cd back to the LVM root (LVM/) and run the configure script

6. Do a "make"

7. Do a "make install"

8. Omit this step if you chose yes for LVM instead of module in "make config".

   Put an "insmod lvm-mod" into your startup script OR check/extend
   /etc/modules.conf (formerly /etc/conf.modules) for/by

      alias block-major-58      lvm-mod
      alias char-major-109      lvm-mod

   to enable modprobe to load the LVM module (don't forget to enable kmod).

9. Add a "vgscan" and a "vgchange -a y" to your startup files
   (/sbin/init.d/boot with SuSE for eg.) so that the actual volume
   group configuration is online after each reboot.

   Put a "vgchange -a n" into your shutdown script (/sbin/init.d/halt for eg.)
   after dismounting all filesystems.

10. Please remember to keep a lilo.conf entry which is configured to boot
    the previous kernel in case of an emergency!

    Reboot your machine.

11. read the ascii file LVM-HOWTO to go ahead using the LVM
    and read the manuals starting with lvm(8).




If you want to remove the LVM software.

1. change directory to LVM/0.9

2. do a "make remove"

go to step 6 below if you have a stock kernel already containing the LVM driver

3. save your /usr/src/linux/.config

4. delete and reinstall the kernel source tree

5. restore /usr/src/linux/.config

6. change directory to /usr/src/linux

go to step 8 below if you have a stock kernel already containing the LVM driver

7. make oldconfig

continue with step 9

8. make (menu|x)config # deselect LVM here

9. rebuild the kernel and reboot
