How To Install drbdlinks on Fedora 34

drbdlinks is Program for managing links into a DRBD shared partition

Introduction

In this tutorial we learn how to install drbdlinks on Fedora 34.

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.

We can use yum or dnf to install drbdlinks on Fedora 34. In this tutorial we discuss both methods but you only need to choose one of method to install drbdlinks.

Update yum database with dnf using the following command.

sudo dnf makecache --refresh

The output should look something like this:

Fedora 34 - x86_64                               20 kB/s | 6.6 kB     00:00
Fedora 34 openh264 (From Cisco) - x86_64        1.4 kB/s | 989  B     00:00
Fedora Modular 34 - x86_64                       68 kB/s | 6.5 kB     00:00
Fedora 34 - x86_64 - Updates                    3.5 kB/s | 6.2 kB     00:01
Fedora Modular 34 - x86_64 - Updates             17 kB/s | 5.9 kB     00:00
Metadata cache created.

After updating yum database, We can install drbdlinks using dnf by running the following command:

sudo dnf -y install drbdlinks

Update yum database with yum using the following command.

sudo yum makecache --refresh

sudo dnf remove drbdlinks
