Important

Review this article before applying the update.

Important

If your Azure Stack Hub instance is behind by more than two updates, it's considered out of compliance. You must update to at least the minimum supported version to receive support.

Update

  • Applicable: This issue applies to release 2408.
  • Cause: An internal failure of Live Update forces the update method to use FRU instead, which significantly extends the overall update period. Due to this issue, each node update takes an additional 5 hours to complete (approximately).
  • Remediation: If you have more than 8 node stamps, it's advised that you delay your updates if possible, until a hotfix/inline fix is released.
  • Occurrence: Common.

Compute

Azure Kubernetes Service on Azure Stack Hub

  • Applicable: This issue applies to release 2311 and later.
  • Cause: Azure Kubernetes Service on Azure Stack Hub, currently in preview, is being discontinued and will not be released to general availability. If you try to register a new subscription to the Microsoft.Containerservice resource provider, the registration stays in the Registering state. If you try to create a new managed Kubernetes cluster or access existing managed Kubernetes clusters, you might see the raining cloud error screen.
  • Remediation: Microsoft is aware of the problem and is working on a fix.
  • Occurrence: Common.

  • Cause: The Standard Load Balancer portal blades for Logs and Diagnostic settings both show errors displaying the content.
  • Remediation: The Standard Load Balancer in Azure Stack Hub does not support any diagnostic features.
  • Occurrence: Common.

  • Occurrence: Common.

Shutdown using Start-AzsCryptoWipe does not work

  • Applicable: This issue applies to release 2311.
  • Cause: In some cases when you run the Start-AzsCryptoWipe command to shut down Azure Stack Hub, one of the physical machines is not powered off.
  • Remediation: If you see that any physical machine is not powered down, you must turn off that machine through the Baseboard Management Controller (BMC).
  • Occurrence: Common.

Storage

False storage volume utilization alert in Test-AzureStack report

  • Applicable: This issue applies to release 2311 and later.
  • Cause: The new OS build with 2311 introduces a new system alert for thin provisioning: an alert is raised when the storage pool usage exceeds 70%. Fixed-size volumes are used in the Azure Stack Hub deployment, so the 70% threshold is always exceeded. You can find this warning in the Test-AzureStack reports.
  • Remediation: You can ignore the alert in the Test-AzureStack report. Microsoft is aware of the issue and is working on a fix.
  • Occurrence: Common.

Portal

  • Applicable: This issue applies to release 2311.
  • Cause: In the Azure Stack Hub user portal, under the Virtual Networks section, there are three new options for virtual networks: DNS Servers, Flow Timeout, and BGP community string. You can successfully modify the DNS configuration using the DNS Servers option. However, attempts to use the Flow Timeout and BGP community string options result in a failure within the portal notifications. No changes are made to the underlying services; the errors are only in the portal.
  • Remediation: Microsoft is aware of the problem and is working on a fix.
  • Occurrence: Common.

False deployment error in portal for API app deployment

  • Applicable: This issue applies to release 2311 and later.
  • Cause: Some users might see an error message with error code templateLinkAndJson when deploying an API application from the marketplace, even though the deployment was successful.
  • Remediation: Check your API app after deployment to ensure deployment was successful. Microsoft is aware of the problem and is working on a fix.
  • Occurrence: Common.

Resource providers

Incorrect rotation status after secret rotation of resource provider certificates

  • Applicable: This issue applies to all Azure Stack Hub add-on resource providers.
  • Cause: After secret rotation, the rotation state shows as "in progress" even though the rotation completed successfully, the provisioning state shows "successful," and the expiration date is updated.
  • Remediation: None. No impact to your system or workloads.
  • Occurrence: All supported versions of Azure Stack Hub.
