[Bug 1895343] Re: Microsoft Azure Enablement: azure-lb & azure-events missing in Bionic
** Description changed: + [Impact] + + azure-lb and azure-events are handful resources agents if one is + maintaining a cluster on Azure platform. azure-lb facilitate the + operation of a load balancer implemented by Azure and azure-events + notifies when some events in the Azure platform happens to help the + cluster to adjust itself. + + In Focal, both resource agents are available, however, to keep all the + releases in the same state a patch fixing a bug in azure-lb is needed. + This is the upstream patch: + + https://github.com/ClusterLabs/resource-agents/commit/d22700fc + + In Bionic, those agents are not available, and the full features will be + backported as a way to better support the HA stack on Azure.

For Focal... I think we should SRU: [rafaeldtinoco@groovy resource-agents]$ git log --oneline v4.5.0..HEAD -- heartbeat/azure-lb d22700fc azure-lb: Don't redirect nc listener output to pidfile that is the only fix I backported to Bionic (in the SRU being proposed) and I think that it should also be SRU'ed to Focal as the fix is straightforward.

[Bug 1895343] Re: Microsoft Azure Enablement: azure-lb & azure-events missing in Bionic
For Bionic, I think it's okay to have azure-lb backported as it is a standalone shell script that will act as a resource agent. Unfortunately I don't see AzEvents being backported and accepted as SRU just because it takes some more changes for it to be integrated to existing Bionic resource-agents. These are the patches implementing the AzEvents (renamed to azure-events later): 328bb0e 2018-07-18 10:11 -0700 TNiekamp AzEvents: Use configure to replace shebang line 416f0b1 2018-09-14 15:21 -0700 TNiekamp Implemented review feedback from krig e7b1a18 2018-10-17 09:10 +0200 KGrönlund dev: AzEvents: Use pacemaker commands to set standby 9890deb 2018-10-17 09:06 +0200 KGrönlund dev: AzEvents: Start using ocf.py ca15b9d 2018-10-18 09:23 +0200 KGrönlund dev: azure-events: Add custom user agent and it would require the ocf.py to be brought as well, and then all the compilation changes regarding auto tools to recognize python scripts... not suitable for a SRU, for sure. With that said, I'll keep my merge request to bring *at least* the azure-lb resource agent to Bionic at: https://code.launchpad.net/~rafaeldtinoco/ubuntu/+source/resource- agents/+git/resource-agents/+merge/392746 My suggestion to those who need azure-events is to either migrate to Focal or Groovy, or to use the back-ported Groovy HA stack at: https://launchpad.net/~ubuntu-ha/+archive/ubuntu/groovy-ha-stack ** Changed in: resource-agents (Ubuntu Bionic) Status: Confirmed => In Progress -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1895343 Title: Microsoft Azure Enablement: azure-lb & azure-events missing in Bionic To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/resource-agents/+bug/1895343/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
