** Description changed: [Impact] azure-lb is a handful resources agent if one is maintaining a cluster on - Azure platform. azure-lb facilitate the operation of a load balancer + Azure platform. azure-lb facilitates the operation of a load balancer implemented by Azure. In Focal, azure-lb is 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, the agent is not available, and the full feature will be backported as a way to better support the HA stack on Azure. The changes are self-contained since each resource agent is maintained as a separate script. [Test Case] On Azure create a Corosync/Pacemaker cluster with 3 VMs and make sure you have the following CIB: node 1: vm01 node 2: vm02 node 3: vm03 primitive lb-healthprobe azure-lb \ params port=8000 nc="/bin/nc" \ op monitor interval=10 timeout=20 property cib-bootstrap-options: \ have-watchdog=false \ dc-version=2.0.3-4b1f869f0f \ cluster-infrastructure=corosync \ cluster-name=clufocal \ no-quorum-policy=stop \ last-lrm-refresh=1603822692 \ maintenance-mode=false The status of the cluster should be: $ sudo crm status Cluster Summary: * Stack: corosync * Current DC: vm02 (version 2.0.3-4b1f869f0f) - partition with quorum * Last updated: Wed Dec 9 18:16:32 2020 * Last change: Wed Dec 9 18:16:30 2020 by root via crm_attribute on vm01 * 3 nodes configured * 1 resource instances configured Node List: * Online: [ vm01 vm02 vm03 ] Full List of Resources: * lb-healthprobe (ocf::heartbeat:azure-lb): Started vm02 To take advantage of azure-lb resource agent you need to have an Azure load balance configured. You can find information on how to do it here: https://docs.microsoft.com/en-us/azure/load-balancer/quickstart-load- balancer-standard-public-cli [Where problems could occur] As mentioned previously each resource agent is maintained as a separate script, so for Focal where the agent is already there we can have a problem in the existent azure-lb resource agent. In Bionic the risk of a regression is quite low since the agent does not exist. [Original description] This bug is part of the HA enablement for Microsoft Azure Cloud.
