Situation
After updating the "resource-agents" package, the pacemaker cluster is not able to start the "azure-lb" resource in an Azure Cloud HA Cluster.
The following is a snippet of the error message in the cluster:
... node1 azure-lb(rsc_nc_HN1_HDB01)[3410]: ERROR: /usr/lib/ocf/resource.d/heartbeat/azure-lb: line 99: kill: (3437) - No such process
This issue can occur in Azure Cloud when IPv6 is disabled in the system (for example "ipv6.disable=1" is set in the kernel parameters).
The following "resource-agents" package versions are affected:
- SLE HAE 15 SP3: resource-agents-4.8.0+git30.d0077df0-150300.8.40.2
- SLE HAE 15 SP4: resource-agents-4.10.0+git40.0f4de473-150400.3.25.2
- SLE HAE 15 SP5: resource-agents-4.12.0+git30.7fd7c8fa-150500.3.6.2
The following is a snippet of the error message in the cluster:
... node1 azure-lb(rsc_nc_HN1_HDB01)[3410]: ERROR: /usr/lib/ocf/resource.d/heartbeat/azure-lb: line 99: kill: (3437) - No such process

- SLE HAE 15 SP5: resource-agents-4.12.0+git30.7fd7c8fa-150500.3.6.2
Resolution
This issue is reported to Engineering and a fix is currently being worked on.
A workaround is to downgrade "resource-agents" package to the previous version:
- SLE HAE 15 SP3: resource-agents-4.8.0+git30.d0077df0-150300.8.37.1
- SLE HAE 15 SP4: resource-agents-4.10.0+git40.0f4de473-150400.3.22.
- SLE HAE 15 SP5: resource-agents-4.12.0+git30.7fd7c8fa-150500.3.3.1
If downgrading the "resource-agents" package version is not possible, please open a Support Case to request a PTF (Program Temporary Fix).
