R1Soft: Replication driver missing

I was discovery that the R1Soft server hosted for client server getting the following error,

An exception occurred during the request. Replication driver missing; Unable to open driver at '/dev/hcp'; No such device or address.

To get this issue fixed, you should make sure that you have the kernel similar version with your kernel-header. Then you could verify if the Linux Hot Copy module is loaded. To verify the them,

To check the kernel version,

uname -r

To check the kernel-header version,

yum list kernel-devel

If you have PAE, xen or Enterprise kernel, use theĀ corresponding version like kernel-PAE-devel, kernel-xen-devel or kernel-ent-devel.

Next, build the kernel header with source,

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

Next, restart the CDP-Agent to load the new driver,

/etc/init.d/cdp-agent restart

After that, you may check if the module loaded

lsmod | grep hcpdriver

You have done and the error should away by now.

  1. Thank you!

    I installed the free HCP before updating my kernel… I was going a little wonky trying to figure out how to fix as hcp-setup was spitting a very similar error msg. Installing kernel-devel, then hcp-setup –get-module solved it. Ran & now have a hot copy in /dev/hcp1 (/var/hotcopy/sda1_hcp1)

  2. Hello,

    I have;


    I can’t get hcp driver to work. I’v tried rebuilding the module with;

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

    but no luck yet
