We currently have virtual (xen) servers from a host here in the UK and back up to an Idera R1Soft / ServerBackup system in the US.

One of our servers absolutely refuses to compile the kernel module. Has anybody else seen this issue? Our server host has exhausted all their ideas, the backup service provider doesn't want to help as it isn't their server that we're backing up.

This is what we get:

root@web2 [~]# serverbackup-setup --get-module

Has anybody seen this?

Thanks!

What's up with the odd kernel version? Can you at least tell us what Linux distribution and version you're using? –  ewwhite Oct 16 '13 at 11:55
    
Hey, good question. Our host has tried an array of different kernel versions. This one happens to match another server that works fine (though its 32bit on the working server). The OS is Centos 6.4. –  JimBlizz Oct 17 '13 at 14:33
    
Did you get this resolved? Recommend removing all kernel headers, installing new kernel from official sources, then installing matching kernel headers. Reboot the server and then try to build. We have seen some issues with linking in kernel header trees but that does not seem to be the problem here. –  jeffatrackaid Nov 7 '13 at 14:18

I noticed that the kernel version here is pretty odd - 2.6.32.61... So it looks like a hand-compiled vanilla kernel. If you don't have a specific reason for doing this, you should probably be on a kernel sourced through the RHEL/CentOS ecosystem, or at least deployed via RPM.

The hotcopy/serverbackup/cdp driver module leverages your running kernel source to collect the headers, scp them to an Idera/R1Soft build server, compile on the build server, then ship an appropriate compiled module back to your system. It's an odd process, but that's how they protect their intellectual property.

Go ahead and contact Idera for support. As what they're missing. If you're using an RPM-based distribution, this process usually wants the kernel-headers package installed.
