NetApp/trident v22.10.0

on GitHub

Changes since v22.07.0

• IMPORTANT: Kubernetes 1.25 is now supported in Trident. Please upgrade Trident prior to upgrading Kubernetes.
• IMPORTANT: Trident will now strictly enforce the use of multipathing configuration in SAN environments, with a recommended value of find_multipaths: no in multipath.conf file. Use of non-multipathing configuration or use of find_multipaths: yes or find_multipaths: smart value in multipath.conf file will result in mount failures. Trident has recommended the use of find_multipaths: no since the 21.07 release.

Fixes:

• Fixed issue specific to ONTAP backend created using credentials field failing to come online during 22.07.0
  upgrade (Issue #759)
• Docker: Fixed an issue causing the Docker volume plugin to fail to start in some environments (Issues #548, #760).
• Fixed SLM issue specific to ONTAP SAN backends to ensure only subset of data LIFs belonging to reporting nodes are published.
• Fixed performance issue where unnecessary scans for iSCSI LUNs happened when attaching a volume.
• Removed granular retries within Trident's iSCSI workflow to fail fast and reduce external retry intervals.
• Fixed issue where an error was returned when flushing an iSCSI device when the corresponding multipath device was already flushed.

Enhancements

• Kubernetes: Added support for Kubernetes 1.25.
  • Added new operator yaml (bundle_post_1_25.yaml) without a PodSecurityPolicy to support Kubernetes 1.25.
• Kubernetes: Added a separate ServiceAccount, ClusterRole, and ClusterRoleBinding for the Trident Deployment and DaemonSet to allow future permissions enhancements.
• Kubernetes: Added support for cross-namespace volume sharing.
• All Trident ontap-* storage drivers now work with the ONTAP REST API.
• Added support for LUKS-encrypted volumes for ontap-san and ontap-san-economy storage drivers.
• Added support for Windows Server 2019 nodes.
• Added support for SMB volumes on Windows nodes through the azure-netapp-files storage driver.

Deprecations:
