Ubuntu HA - Pacemaker Resource Agents Supportability
After discussions among Ubuntu Developers, it was decided that Ubuntu project should focus in splitting all existing Pacemaker Resource Agents into different categories:
- Resource Agents: [main]
- Resource Agents: [universe]
- Resource Agents: [universe]-community
- Resource Agents: [non-supported]
- Resource Agents: [deprecated]
Note: There is a to split resource agents into different packages so supported agents can be installed independently.
Resource Agents: [main]
Agents in this list are supported just like any other package available in [main] repository would be.
