I was discovery that the R1Soft server hosted for client server getting the following error,
1 | 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,
1 | uname -r |
To check the kernel-header version,
1 | yum list kernel-devel |
If you have PAE, xen or Enterprise kernel, use the corresponding version like kernel-PAE-devel, kernel-xen-devel or kernel-ent-devel.
Next, build the kernel header with source,
1 | r1soft-setup --get-module --no-binary |
Next, restart the CDP-Agent to load the new driver,
1 | /etc/init .d /cdp-agent restart |
After that, you may check if the module loaded
1 | lsmod | grep hcpdriver |
You have done and the error should away by now.
