Logical Volume Manager Installation 21/02/2000 Installing this package will create various files in /sbin, /usr/man/man8 and an optional shared library in /lib. If you don't have a stock kernel including LVM you have to patch your kernel with the corresponding patch from . 1. Change to LVM/0.8final/ 2. If you don't have a kernel including the LVM driver, choose the corresponding patch from or one of the mirrors (replace asterixes below with those of the corresponding patch of your choice) and patch the kernel by gzip -dc patch-*.*.*-LVM-*.*.gz | ( cd /usr/src/linux; patch -p1) An example for patch-*.*.*-LVM-*.*.gz could be patch-2.3.46-LVM-0.8final.gz 3. cd to /usr/src/linux and configure LVM and loadable module support if you like to load it as a module (see /usr/src/linux/README for instructions) by "make config/menuconfig/xconfig" (whatever you prefer) 4. Build a new kernel 5. cd back to the LVM root (LVM/0.8final/), edit make.tmpl and change the TOP macro to the directory you untared LVM too 6. On SMP systems uncomment "MAKEFLAGS = -j2" in make.tmpl and change 2 too the number of your cpus (some guys prefer number of cpus # 1 ;-{). If you decide to link with the LVM archive library, change tools/Makefile corresponding (see comment "Link decision") Do a "make" 7. Do a "make install" 8. Omit this step if you choosed yes for LVM instead of module in "make config". Put an "insmod lvm-mod" into your startup script OR extend /etc/modules.conf (former /etc/conf.modules) 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 keep in mind to have a lilo.conf, 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 like to remove the LVM software. 1. change directory to LVM/0.8final 2. do a "make remove" goto 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 goto 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
