I have the following: Two node cluster each running Fedora release 8 Kernel 2.6.23.8-63.fc8 Heartbeat-2.1.2-2.fc8 (RPM) drbd-8.0.8 - Installed from source drbdlinks-1.09-1 (RPM)
We use this cluster for our intranet server and the drbd resource has both apache and mysql installed on it. We are required to upgrade our kernel due to local security policy. This will be done via a standard yum update. Reading through the drbd docs I see the following: "Note that any kernel upgrade will require you to rebuild and reinstall the DRBD kernel module to match the new kernel." I did not do the original install of this cluster, so I'm a little vague on how to proceed. I am not clear on what has to be done to upgrade the km. Do I stop heratbeat on both systems, upgrade the kernel, recompile the drbd software and start heartbeat again? Repeat on other node. Also, does anything have to be unmounted for all this not to break something? Since this is a heavily used server, I would hate to render the service unusable due to this upgrade? Any insight would be appreciated.
