  • Article

Summary

  • N/A

Fixes rolled up from previous hotfix releases

  • Improved stability of SDN components.
  • Improved the PnP device attached alert and moved it back to Preview.
  • Optimized reading of disk IOPS values to support VMs with a large number of data disks.
  • CRP will self-heal a VM with a SCSI disk that failed to attach instead of requiring operator removal of the disk from the VM.
  • Fixed an issue in VM power-off operation in which CRP service always ignored the value of the non-graceful VM shutdown parameter.
  • Fixed an issue that prevented health remediation of the Compute Host Agent service.
  • Fixed a bug in incremental disk snapshots in which a failed snapshot can block any future snapshot operation.
  • Fixed a mismatched cluster name issue in FRP.
  • Fixed an issue that could impact updating to 2108.
  • Resolved an issue in which the Create a Virtual Machine image dropdown displays image options that are not available or were not downloaded to the stamp.
  • Fixed an issue in which the PrivateWorkingSet queried value overflows if larger than 4 GB.
  • Removed some unnecessary detailed error information on the administrator portal.
  • Improvements to support tools.
  • Resolved an issue with some Key Vault applications being in an unhealthy state while updating from 2102 to later builds.
  • Add retry for get-volume requests in Test-AzureStack infra capacity check.
  • Shorten the "break-glass" tokens and make them human-readable.
  • Fixed a bug related to physical disk health when repairing a node with SED drives.
  • Improved Datapruner processing to minimize actor timeout alerts.
  • Enabled rotation of health agent SSL certificate as part of internal secret rotation.
  • Added graphs to Storage area that show volume performance.
  • Improved logic for incremental snapshot creation and deletion.
  • Improved resiliency in PEP startup script.
  • Fixed an issue in which System Center Operations Manager (SCOM) was unable to close operator portal alerts.
  • Improved auto-remediation workflow for memory utilization.
  • Improved incremental snapshot creation and deletion.
  • Addressed an issue in the Reset-CloudAdminPassword cmdlet.
  • Updated Network Controller to fix bugs in PA VIP allocation and IP-MAC leaks.
  • Improved performance when querying for usage data.
  • Improved resiliency of compute admin operations.
  • Removed overly verbose logging from Software Load Balancer VMs.
  • Fixed a memory leak issue and improved memory efficiency for monitoring services.
  • Fixed an issue in which the backup blade showed a "rainy" page when backup share was inaccessible.
  • Fixed an issue that prevented transcript collection when closing Privileged Endpoint (PEP) session.
  • Fixed a multi-tenancy website security issue.
  • Improved reliability of update from 2008 to 2102.
  • Fix for adding availability set to SQL VM in the SQL VM creation process.
  • Fix for setting storage size in SQL VM configuration to more than 1000 GB.
  • Fixed group-based authorization errors for users that require group expansion.
  • Newer API version support for Key Vault resource provider. The Key Vault control plane supports the 2019-09-01 API version, and the Key Vault data plane supports API version 7.1.
  • Added banner to warn users when a certificate will expire soon.
  • Fix to show accurate status of node in portal if a repair operation on it has failed.
  • ETW trace sessions are configured to use 16 MB of non-pagedpool memory. Trace sessions now report lost event count (if any) per session, during ETL file rotation in TraceCollector Eventlog. This releases critical non-paged pool memory for other services on hosts and VMs. Also fixed various bugs in Tracecollector.
  • Fixed bugs that increased memory pressure on infrastructure.
  • Fixed bugs in AD FS and Azure Stack Graph to improve deployment and upgrade reliability.
  • Fixed bugs in SRP and DiskRP in which performance counters were missing in the WAC client.
  • Fixed a bug in resource provider (for example, Event Hubs) deployment, update, or secret rotation. The operation previously failed with no apparent failure cause. The fix allows the operation to complete successfully.
  • Fixed a bug that incorrectly raised a PnPDevice.Attached alert for a set of devices (mouse, keyboard, etc.) that were safe.
  • Set memory alert to preview.
  • Addressed an issue with host agent monitors.
  • Fixed a trust relationship issue with container applications in FabricRing.
  • Improved RdAgent availability by removing empty RdAgent files.
  • Improved reliability of full update.
  • Extended the update readiness checks to cover more Service Fabric health and VM health checks; for example, memory usage and storage disk capacity checks.
  • Updated memory configuration for VM sizes Standard_NC16as_T4_v3 and Standard_NC64as_T4_v3.
  • Removed legacy SRP SQL instances and DB files to free up stamp resources.
  • Fixed a bug in which the cluster status can be stuck in "Configuring Storage" after adding a new node.
  • Fixed health package registration, removing duplicate artifact creation.
  • Fixed a bug that sometimes caused health blades in the operator portal to become unavailable.
  • Fixed a bug in which BCDR runner logs filled up MASLogs folders on physical hosts.
  • Added monitoring of WMIProvider health and remediation.
  • Added Network Controller IMOS size check to Test-AzureStack.
  • Fixed a bug in SSL certificate validation during internal secret rotation.
  • Fixed process watchdog memory leaks.
  • Updated Defender platform to version 4.18.2103.7.
  • Enabled the alert module for customers depending on Syslog for alerts. The services will continue to emit alerts to the Syslog pipeline.
