2022.4.5

Release date: 6 April 2023

Important:

We have removed the Automation Suite 2022.4.5 installation packages due to a major bug affecting Automation Ops. We recommend upgrading to Automation Suite 2022.4.6 instead, which includes a bug fix for Automation Ops.

Security enhancements

We continue to provide security updates and patches to address Common Vulnerabilities and Exposures (CVEs).

Bug fixes

• We have fixed an issue causing the configureASDisks.sh script to provide inaccurate calculations when extending the data disk.

• The prerequisites tool now checks if the size of the /var/log directory is at least 8 GB.

• Automation Suite upgrades would fail due to bag attributes on certificates. The issue no longer occurs.

• Due to an invalid image tag, the Support Bundle tool was unable to execute and process older logs. We have fixed this by correcting the image version in the Support Bundle tool.

• When putting the system in maintenance mode to perform an upgrade operation, the Istio gateway is no longer scaled down to zero to prevent issues affecting the ArgoCD login and cluster_config.json generation.

Known issues

• Erratum January 2024: The replica cleanup script would incorrectly reclaim storage on the nodes. For more details, see the Storage reclamation patch troubleshooting article.

Known issues

• Erratum - added October 11, 2024: In a proxy environment, if the proxy server uses the same port as the TCP port of any other service in the Istio service mesh, such as port 8080, pods cannot communicate with the FQDN. The issue causes the following error:

  System.Net.Http.HttpRequestException: The proxy tunnel request to proxy 'http://<proxyFQDN>:8080/' failed with status code '404'.

  To fix the issue, see the Troubleshooting section.

• Erratum - added August 29, 2024: We have identified certain vulnerabilities associated with the usage of weak ciphers in TLS 1.2. For details on how to mitigate the issue, see How to address weak ciphers in TLS 1.2.

• Erratum - added May 20, 2024: On single-node deployments with in-cluster storage, upgrades from version 2022.4.1 or older fail at the fabric stage due to a rook-ceph migration issue. To prevent the issue, follow the instructions in this troubleshooting article: Single-node upgrade fails at the fabric stage.

• Erratum - added April 19, 2024: In certain situations, Prometheus pods can fail to start due to an out-of-memory (OOM) error. To fix the issue, see the Troubleshooting section.

• Erratum - added April 19, 2024: In certain situations, Ceph metrics and alerts are missing from the monitoring dashboards. To fix the issue, see the Troubleshooting section.

• Erratum - added April 19, 2024: False positive CephMgrIsAbsent alerts are displayed even though there are no storage issues.
