R1soft hcp module error – How to effectively fix this

by | Jul 5, 2021

Stuck with the R1soft hcp module error? We can help you.

Once we upgrade the Kernal version we may come across this error.

As part of our Server Management Services, we assist our customers with several R1soft queries.

Today, let us see how we can fix this error quickly.


R1soft hcp module error

With R1soft CDP backup, we can take full server backup. In addition, we can use it to perform bare metal restoration.

However, once we upgrade the Kernal version on the server, we may face the following error while running the backup:

An exception occurred during the request. The replication driver was not detected (detail: An error occurred while loading the hcpdriver module, please check your system logs; Please run “r1soft-setup –get-module ” on your Agent to install one.

In order to load the hcp driver, we run the following command:

lsmod | grep hcp

If it returns with no value, we know that the hcp driver is not installed on the machine.

In such a case, we proceed with the steps below.

initially, we verify the kernel version:

uname -r

After that, we verify Kernel-devel & Kernel-headers packages. It should match with the Kernel version we have.

rpm -qa | grep kernel

If not, we install the matching version. To do so, we run the following command:

r1soft-setup --get-module
r1soft-setup --get-module --no-binary

Eventually, we restart the CDP agent once.

/etc/init.d/cdp-agent restart

Then we run the following command to load the hcp driver again.

lsmod | grep hcpdriver

We will see the value in return. After all, the backup should run fine using R1Soft.
