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.
At the moment, the fence-agents binary package has been split into two: fence-agents-base and fence-agents-extra. The fence-agents-base binary package contains a set of curated agents which the Ubuntu Server team continuously run tests to make sure everything is working as expected. All the other agents previously in the fence-agents binary package are now moved to the fence-agents-extra.
The fence-agents-base binary package contains the following agents:
fence_mpathfence_scsifence_virsh
Fence Agents: [main]
Agents in this list are supported just like any other package available in [main] repository would be.
