Hi @all,

I have patched my current system kernel (2.6.18.2) and added a new driver. The driver compiled successfully and works without any probs. Now, I have 6 other systems (linux workstations) with the same kernel running and architecture.
How can I export my installed driver module to the other systems without the need to re-compile the other kernels?

Thanks in advance,

Does the output of uname -r show the same on all systems including the one you compiled on if so try copying the driver.ko to the proper directory in the /lib/modules/2.6.18.2/.... (I assume) then run depmod -a and modprobe driver, hopefully it will now work on all of them.

Edit: Typo.

Hi HappyTux,

one mistake I made, was that the clients indeed do have the same kernel but additionally are patched for xen. I thought that this shouldn't be a big deal but unfortunately it didn't work.

When I try your approach I get a
<snip>
dm_raid4_5: disagrees about version of symbol struct_module
</snip>


Isn't there a way to export the compiled module to those other workstations without recompiling their kernel? My problem actually is that even if I wanted to, the clients are all CentOS5 systems and it's not possible to recompile the kernel shipped with it.

Best Regards,

simplyA


P.S:
OUTPUT FROM ONE WORKSTATION:
[root@wks1 ~]# uname -a
Linux wks1 2.6.18-8.el5xen #1 SMP Thu Mar 15 19:56:43 EDT 2007 x86_64 x86_64 x86_64 GNU/Linux
[root@wks1 ~]#

I do have a 2.6.18-8 and not a 2.6.18-2 kernel. sorry.

Edit: Typo

Ok this is getting a little beyond my experience but one thing I do not understand here is you say the CentOS kernel cannot be recompiled so how are you getting this kernel module then if the source cannot be recompiled?? Is this other system not running the same kernel as the rest because this would be the only way it could work the output of the uname -r has to be the same on all the systems for it to have a chance. You might want to see if the CentOS folks have a dedicated support list for these type of problems.

Hi HappyTux,

I'm sorry to have caused confusion on this!

Let me explain it a bit more:
My system does have the same kernel version 2.6.18-8 as the other workstations. The only difference is that a) I have downloaded the kernel from kernel.org (due to the compiling problem) and b) my kernel isn't patched/modified for xen.


Anyway, thanks a lot for your help.
