The problem of improving the reliability of the organization's critical access resources is discussed in this article. We consider the case of a two-node high availability cluster based on Pacemaker and a DRBD distributed file system, which ensures the operation of an organization's website and a MySQL database server in active-passive mode. The configuration is shown for most of the used HA-cluster resources.
