How to do it...
For this recipe, we will use the same two PostgreSQL nodes: pg1 and pg2. We will also continue to assume that our PostgreSQL data is located at /db/pgdata:
- Prevent PostgreSQL or DRBD from starting on system boot on Red Hat-based systems by executing these commands on both servers as a root-capable user:
sudo systemctl disable postgresql-12 sudo systemctl disable drbd
- Debian-based systems should use the following commands to disable PostgreSQL and DRBD instead:
sudo systemctl disable postgresql@12-main sudo systemctl disable drbd
