[upgrade] upgrade procedure should update agent/mc agent/network checker

[Dima Shulyak]

Packages fuel agent, mcollective agent and network checker are part of control plane and not openstack.

Not upgrading them means that bugs fixed in those packages wont affect already deployed nodes.
It also introduces some limitation on changing/adding actions to astute/network checker.

If this will be considered by design, atleast it should be fixed by puppet in case of environment patching, because as for now - they are installed by means of kickstart/preseed configurations.

[Evgeniy L (rustyrobot)]

Nailgun and Astute should support both versions of network checker.
Currently we cannot upgrade network checkers and mcollective agents, here are several reasons
1. it won't help, because after deployment user can run network checker on old cluster with new astute/nailgun
2. openstack patching feature was created to update minor changes for openstack, so, we cannot deliver code which breaks backward compatibility

[Evgeniy L (rustyrobot)]

Dmitry, do we have broken backward compatibility for network checker and mcollective plugins right now?

[Dima Shulyak (dshulyak)]

Network checker/mcollective verify networks compatibility will be fixed with this patch - https://review.openstack.org/#/c/107099/.

Cant say for other mcollective tasks..

1. it won't help, because after deployment user can run network checker on old cluster with new astute/nailgun

that is exectly the reason i created this bug, if we wont upgrade netwok checker/mcollective agents it will be quite easy to breake communication with slaves, perhaps i missed your point

wrong link in prev post - https://review.openstack.org/#/c/107622/

[Evgeniy L (rustyrobot)]

I've talked with Dmitry and he told me that right backward compatibility is not broken.

My suggestion is to add this case in test cases for upgrades and close the bug.

[Evgeniy L (rustyrobot)]

QA team, could you please make sure that you have such test case?

If yes, we can close this bug.

[Evgeniy L (rustyrobot)]

Talked with Dmitry Pyzhov and Dmitry Shulyak, and it looks like we need a way to upgrade nechecker and mcagents.

[Ihor Kalnytskyi (ikalnytskyi)]

What about solution proposed by DShulyak? We can upgrade netchecker and mcagents withing openstack patching. All we need is to add ensures to our puppets.

Please correct me if I'm wrong.

[Dima Shulyak (dshulyak)]

It may be tricky to upgrade mcollective agents this way, we need to restart it, but astute polls mc agent.
So i'm +1 for postponing it, if this is not considered as big issue.

[Ihor Kalnytskyi (ikalnytskyi)]

Postponed to 6.0 due to discussion in mail list [1].

[Evgeniy L (rustyrobot)]

It's not enough to just add 'ensure' for netchecker package in manifests, in this case rollback won't work because previous version of manifests don't have ensure for this package.

[Dima Shulyak (dshulyak)]

I hope it will be covered by patching story.
But it seems we are not going to include slaves update during master node upgrade script execution,
Evgeniy can you mark it as wont fix if it is true?
