Ubuntu HA - Pacemaker Fence Agents Supportability

After discussions among Ubuntu Developers, it was decided that Ubuntu project should focus in splitting all existing Pacemaker Fence Agents into different categories:

  • Fence Agents: [main]
  • Fence Agents: [universe]
  • Fence Agents: [universe]-community
  • Fence Agents: [non-supported]
  • Fence Agents: [deprecated]

Note: There is a current plan to split fence agents into different packages so supported agents can be installed independently.

Fence Agents: [main]

Agents in this list are supported just like any other package available in [main] repository would be.
