IOlimits module not loaded?

[gtongco]

Hi,

I was checking through cPanel LVE Manager and found that although IOlimits were set for the clients, Statistics shows 0 for Ave/Max IO for each of them.

I then tried to run "service lve restart" but it shows the following:

service lve restart
unloading LVE module
ERROR: Module lve is in use
ERROR: Module iolimits does not exist in /proc/modules
loading LVE module
FATAL: Module iolimits not found.

The module is installed:

Package kmod-iolimits-0.1-11.el6.x86_64 already installed and latest version
Nothing to do

This used to run fine but when I checked some of my clients History in cPanel LVE Manager, it showed that the last time IOlimits run was on 7/22.

I\ve the latest kernel, cagefs, etc., installed.

Please help me fix the problem.

Thanks.

According to package name iolimits module was compiled for kernel-2.6.32-320.17.1.lve1.1.9.1.el6.x86_64. This kernel installed but not booted. Please boot correct kernel.

Hi,

But thats because I installed kernel-2.6.32-379.1.1.lve1.1.7.6.el6.x86_64 (beta) last 6 August. Shouldnt that install also have installed the latest iolimits module for that kernel?

Igor also announced in the blogs that kernel-2.6.32-379.1.1.lve1.1.7.6.el6.x86_64 is now in production. Should I install that instead?

So, beta kernels do not include modules needed by it?

Please advise.

Thanks.

Unfortunately, iolimits module currently exists only for kernel-2.6.32-320.17.1.lve1.1.9.1.el6.x86_64

Hi,

Thank you for the information.

Next time Igor should put a list of modules that would break when upgrading kernels or other modules so we won go nuts trying to find out what went wrong.

Booting the old kernel now.

Thanks.

Hi,

Come to think of it, would I break anything else, say another module, if i boot the older kernel? Did the latest kernel update also install other modules that rely on that kernel?

Please advise.

Thanks.

Hi,

iolimits module requires some features which were added to 2.6.32-320.17.1.lve1.1.9.1 kernel, thats why its not available for older kernel. You should also get lve-kmod packages for that new kernel. It should not break anything if you boot 2.6.32-320.17.1.lve1.1.9.1 but its still beta software.
