Introduction

In this tutorial we learn how to install drbdlinks on Rocky Linux 8.

The drbdlinks program manages links into a DRBD partition which is shared among several machines. A simple configuration file, “/etc/drbdlinks.conf”, specifies the links. This can be used to manage e.g. links for /etc/httpd, /var/lib/pgsql and other system directories that need to appear as if they are local to the system when running applications after the drbd shared partition has been mounted. When running drbdlinks with “start” as the mode, drbdlinks will rename the existing files/directories and then make symbolic links into the DRBD partition, “stop” does the reverse. By default, rename appends “.drbdlinks” to the name, but this can be overridden. An init script is included which runs “stop” before heartbeat starts, and after heartbeat stops. This is done to try to ensure that when the shared partition isn’t mounted, the links are in their normal state.
