Description

trying to compile the kernel-2.6.32-358.6.2.el6_lustre.g230b174.src.rpm (by extracting the kernel, configure it and make it)

I get the following msgs:

ERROR: "ipmi_smi_probe_complete" [drivers/char/ipmi/ipmi_si.ko] undefined!
ERROR: "ipmi_si_get_smi_info" [drivers/char/ipmi/ipmi_msghandler.ko] undefined!

any ideas?

thanks,

Ron

Suspect you may have configured your kernel badly with respect to IPMI options. I note that all our regular configs for el6 have IPMI_SI as a built-in, not a module; CONFIG_IPMI_SI=y. Your errors suggest you may have config'ed it as a module.

If not that specific one, still may be some other IPMI config setting.

[Ron Croonenberg]

Hi Bob, yes CONFIG_IPMI_SI was set to m, I set it to y and trying again. Is there a config file that is best used?

thanks,

Ron

One of the configs kept in lustre/kernel_patches/kernel_configs might be a good place to start.

[Ron Croonenberg]

So for example 'config-x86_64-generic-rhel' would probably a good one to use?

[Bob Glossman (Inactive)]

Ron, I'm not too familiar with the example configs in the kernel source tree. I have the vague impression they leave a lot of settings that require manual update and can be set wrong or badly. That's why I recommend starting with one of the configs in the lustre source tree. I know we use those and they work for us.

[Bob Glossman (Inactive)]

another good starting point might be the .config from /usr/src/kernel/<kernel-version>

[Ron Croonenberg]

Hi Bob, yes I noticed that previously, about the configs that come with the kernel.

I just extracted the source rpm, with cpio. (lustre-2.4.0-2.6.32_358.6.2.el6_lustre.g230b174.x86_64_gd3f91c4.src.rpm) but I don't see any kernel configs in there? (if it is elsewhere, do you have a URL?)

thanks,

Ron

Ron, I was referring to the .config in the root /usr/src/kernel tree that is part of the kernel-devel rpm. As far as I know you must have the kernel-devel rpm installed in your build environment in order to build any add on kernel modules, including those that are in lustre.

[Ron Croonenberg]

Hi Bob, I do have kernel-devel etc installed. I did extract the lustre kernel in a different directory though... but I don't think that is the issue. it is compiling.. I'll see if it gets past the IPMI stuff.

[Bob Glossman (Inactive)]

As a specific example you can copy the .config from the installed linux-devel, for example /usr/src/kernels/2.6.32-358.14.1.el6.x86_64/.config, into the top dir of your extracted kernel. Then you can use that as the starting point to make manual changes using for example 'make menuconfig'. You can do the same with a config from the lustre tree, for example lustre/kernel_patches/kernel_configs/kernel-2.6.32-2.6-rhel6-x86_64.config

Hello Bob,

thanks! I am trying to compile the kernel using the config from the lustre tree

Ron

[Ron Croonenberg]

ok .. it all seemed to work. thanks!
