r1soft | r1soft-setup –get-module failed

Sometimes you may end up with the following error while trying to install CDP agent in the server.


========================
root@server [~]# r1soft-setup –get-module

=========================

This needs kernel-devel and kernel-headers to be installed to resolve the issue. For that we can use the following command.


===========
yum install kernel-devel
yum install kernel-headers
===========

Please note that the above “yum install —” commands would try to install the kernel-devel and kernel-headers for the higher version of kernel installed in the server. Because of this I could not install it using yum straight away.


===========
root@server [~]# yum install kernel-devel

Nothing to do
===========

Higher version kernel “2.6.32-358.18.1.el6.x86_64” is already present in server, thats the reason we are hitting this error. For this, you may need to remove the rpm packages “using rpm -e” related to higher version kernel since it is not currently up and running.

“PLEASE MAKE SURE YOU ARE NOT REMOVING THE ONE OF CURRENT UP KERNEL, THIS CAN TOTALLY MESS UP THINGS AND CAN BRING DOWN THE SERVER”

Here the current kernel up and running is as follows:


===========
root@server [~]# uname -r
2.6.32-279.el6.x86_64
===========

So I tried to make a slight change in “yum install” command. This would install the kernel-devel for current UP kernel.


===========
# yum install kernel-devel-$(uname -r)

root@server [~]# yum install kernel-devel-$(uname -r)

===========

If it still fails to install with the above command, you may need to finally install the kernel module manually. For this, you should google search the corresponding r1soft kernel module for the current UP kernel.

In my case, I could grab the hcp module from the url “http://darketab.com/robots/sym/root/lib/modules/r1soft/hcpdriver-cki-2.6.32-279.el6.x86_64.ko”. Then I did the following manual steps to load in properly.

Load the driver over to path “/lib/modules/r1soft/”

Make a symlink link to hcpdriver.o
root@server [~]# ln -s /lib/modules/r1soft/hcpdriver-cki-2.6.32-279.el6.x86_64.ko /lib/modules/r1soft/hcpdriver.o

Confirm the symlink
root@server [~]# ll /lib/modules/r1soft/hcpdriver.o
lrwxrwxrwx 1 root root 58 Sep 15 03:52 /lib/modules/r1soft/hcpdriver.o -> /lib/modules/r1soft/hcpdriver-cki-2.6.32-279.el6.x86_64.ko

Restart CDP agent
root@server [~]# /etc/init.d/cdp-agent restart

Confirm it is running or not
root@server [~]# /etc/init.d/cdp-agent status
/etc/init.d/cdp-agent status: cdp (pid 32372) running

Confirm the hcp driver is loaded now
root@server [~]# lsmod | grep hcp

============================================

You are done with CDP agent installation 🙂

Now proceed with configuration of CDP agent in CDP server(from the panel).
