High Availability Clustering with Corosync and DRBD

der hans Audience: Intermediate Topic: SysAdmin Corosync and DRBD can be used to add high availability clustering for services that don't support it. Some services might internally support clustering or failover, but be dependent on components that don't. Corosync is a framework for reliable intra-cluster communication. Using corosync configuration, you can manage resources such as IP addresses, filesystems and services to failover to a secondary server. Example services include web servers, databases and message brokers. The presentation will cover basic corosync configuration for resource control and DRBD configuration for failover filesystems. MySQL will be used as an example service for the failover configuration. Presentation:
