Here are the steps to resolve the module error
a) run this command: serverbackup-setup –get-module >> to check module build successfully or not.
If both headers and devels are available then restart the CDP-agent on the server.
If there is output as shown below then we need to build the module manually to do this follow the below steps:
#serverbackup-setup –get-module
Building header archive.
Failed to get a suitable module for this system: Failed to connect to a remote server.
get module failed.
Failing back to old get-module.
To resolve this find rpm packages for the headers and devels of the installed kernel.
Follow the below steps to install headers and devels for the installed kernel on the server:
1) use url >> http://rpm.pbone.net/index.php3/ >> to find the kernel headers and devels
After finding rpm packages for the headers and devels then install them on the client-server by using the below steps:
a) copy the link address of devels and headers from the above URL and use the command: wget (paste the copied link address) and then use rpm -ivh ***.rpm to install headers and devels.
After this restart, the CDP-agent and run lsmod || grep hcp command to check the module is built or not.
If still no success then reboot the server to resolve this issue.
