Help with redhat install

Hello!!
I am trying to get lvm working on redhat 7.1 with kernel
2.4.2-2. I down loaded the source rpm's 1)
lvm-iop-0.9.1_beta6-1.src.rpm 2)
lvm-iop-patchgen-0.9.1_beta6-1.src.rpm and the base rpm 3) lvm-base-1.1-1.i386.rpm. I did a rpm --rebuild and ran the rpm command and all seemed to install well with no problems. The problem I did discover is that there is no lvm dir. in /proc and the lvm-mod is nowhere to be found. I was under the impression that kernel 2.4 has lvm already built in. I did a insmod lvm-mod and modprobe lvm-mod and nada. I cannot figure out what I am doing wrong or if I should not be using this version of lvm and use lvm 1.0 instaed (will it work on redhat?). Thanks, Chris.

Although 2.4.2-2 has lvm support built in I don't believe it is enabled in the default kernel. I think you have to recompile the kernel and enable it.

I forget what version is in the kernel. With lvm 1.0 just released you may wish to patch the kernel source to the latest level so it will work with lvm 1.0 and then recompile.

If you have to recompile the kernel to get LVM support and download the userland lvm tools (since I don't see an lvm rpm), I don't think that quite qualifies as "built in."

Nevermind. I guess I would have been right if you were talking about RedHat, and not the kernel that comes with it. :)

Sorry,

Hello!!

I encountered the same pronlems. I was in the supposition the kernel 2.4.2 was already fit for lvm-iop-0.9.1_beta6-1.

The source is indeed suitable for lvm, but it still has to be patched with the patchgenerator.

I have the same kernel as yours, and all has to be patched and recompiled

0) make a bootable floppy (rescuefloppy) of the existing kernel

1) patch the sources (you must have the sources)
`patch -p1 < /../../../lvm-0.9.1_beta?-2.2.18.patch'

2.2.18. may be another version, coming from the rpm-package chosen.
This step is necessary, the source still needs to be patched. I skpped this step once, because I assumed the soures were fit for LVM, but this step needs to be done however.

2) cd ../../source-directory of linux/
make mrproper
make xconfig

NOW load from ../configs/<your kernel-configuration>
Next to your kernel-source there has to be a directory, named configs.
In that directory, configs, there is a configuration-file, for diverse architectures and usages (BOOT, normal) Choose the desired architecture and usage (probably *-i386-)
AFTER loading the configurationfile from ../configs, choose the submenu of `RAID and LVM support'
THEN choose how you want to compile, as a module or directly into the kernel.

3) make dep
4) make bzImage
5) make bzdisk - if you use a floppy -
OR
make install - if you have lilo installed.
6) if have chosen the lvm (in make xconfig) to be used as a module
make modules
make modules install
7) copy the kernel image (bzImage) to the place were your regular
bootable kernel is found
8) eventually have a bootable floppy readyof the new kernel
OR/AND update the /etc/lilo.conf, to have one or both kernels
available.
