Need help with LVM on RedHat 7.1

Quoted 3 lines

I have been holding my breath for 2.4 for so long and as I download and install RedHat 7.1 with 2.4.2-2, I find that LVM is not by default configured.

LVM is not by default configured because the lvm on the kernel (0.9.1beta2) is broken AFAIK.

vgscan(1) reports no lvm.o module found.

you should appy this patch to the initscripts also AFAIK

So I get the sources and compile with RAID and LVM marked as modules.

you should get the new lvm userland programas and kernel module from :

ftp://ftp.sistina.com/pub/LVM/0.9.1_beta/

until the upgraded kernel module and programs get into the oficial kernel.

My make menuconfig; make dep; make clean; make bzImage are all fine. Based on some docs, I was now supposed to do 'make modules'.

while building a RH kernel don't forget to copy your configuration to a safe place and do a $(make mrproprer) before a $(make menuconfig) or you could end having strange dependency problems from what is left on the kernel-source RPM

if you follow the LVM documentation you are going to be safe, i just happened to make it work for RH7.1beta and LVM 0.9.1beta6.

and for sure, adding a new patch to the kernel SPEC and rebuilding to get new RPMS is a nice way to get it working.

best regards,

Carlo

Thanks, but I usually don't use Beta on a production box and also RedHat 7.1 comes with a rather old version of lvm, I think 0.8final.

But the compile errors I'm getting are two basics to have passed QA of any distributor...I just recompiled again with only LVM enabled and not RAID and MD
and was getting syntactical errors (compile errors) leaving to belive that some .h
file is missing.

I will try the 'make mrproprer', maybe that'll fix it...

sorry, i think i didn't make myself clear.

RedHat 7.1 DOESN'T come with lvm enabled, because the lvm that is inside the kernel (not RedHat's but the one from Linus) and that they ship (2.4.2-2) is a broken one (0.9.1beta2)

they didn't package the lvm userland utilities neither, i guess because of that.

BUT, you can make it work easily if you download the kernel module and userland utilities and patch your kernel as explained on sistina's documentation.

i just happened to make it work this way on a Red Hat 7.1 beta system using the 0.9.1beta6 tar from sistina, so i think this should work on a Red Hat 7.1 final system.

i guess just because noone even QA this kind of configuration ;)

i hope so, as the kernel should compile, after all, RedHat need to compile it in order to package.

but as i explained before, having an lvm module on your kernel is just one step on having an lvm working system, you are going to need the lvm userland utilities, and the ones that match your kernel module.

that is why i sugested to better download a new kernel module/userland and patch your kernel before even compiling.

also don't forget to change your /etc/init.d/halt script as explained on the sistina's documentation.

and as for running "betas" on production, don't forget that the 0.9.1lvm is still on beta.

Carlo
