[pve-devel] [RFC ha-manager v2 0/3] add 'stopped' state for resources

[Thomas Lamprecht]

Some discussion with Dietmar resulted in this idea for solving bug #1160 -
allow HA templates. This solution is not template specific but a general
approach for resources.

You can request that a service gets in the stopped state, where he will be
still recovered on node failures.

It sill has the advantage from Dietmar approach that the LRM ensures that
the service is stopped and thus in a consistent state.

The plan is to rename the states in a later version (PVE 5.0) so that
enabled becomes started. The resulting states would then be:
* started
* stopped
* disabled

Which should help the confusion for user which are not familar with older HA
stacks (e.g. rgmanager).

Thomas Lamprecht (3):
  Resources: add 'stopped' state
  implement 'stopped' state
  add regression test for 'stopped' state
