NetApp/trident v20.10.0

on GitHub

Changes since v20.07.0

• IMPORTANT: If you are upgrading from Trident 19.07 or 19.10 please carefully read this.
• IMPORTANT Trident relies on the trident-autosupport sidecar container to periodically send usage and support telemetry data to NetApp by default. Usage of the trident-autosupport project falls under the NetApp EULA. Automatic sending of this data can be disabled at Trident install time via the "--silence-autosupport" flag.

Fixes:

• Fixed issue of SLM portal login for iSCSI backends (Issue #387).
• Fixed issue where Trident would crash when creating a volume if ONTAP FCP interfaces were present in the target SVM.
• Fixed issue where storage prefix with period would cause backend to fail when updating or creating backend or upgrading Trident from v20.01 (Issue #455).
• Fixed ONTAP SAN drivers to clean up if provisioning fails (Issue #442).
• Kubernetes: Fixed issue that would cause initiators to be removed from the igroup in the ontap-san and ontap-san-economy drivers in non-CSI installations in Kubernetes <= 1.13 (Issue #463).
• Fixed issue where volume resizes may fail when large ONTAP snapshots were present for the FlexVol.
• Kubernetes: Fixed issue where Trident may panic with a concurrent map write (Issue #456).
• Kubernetes: Fixed issue where Trident Operator may create additional service account secrets (Issue #469).
• Kubernetes: Fixed issue where Trident uses old Kubernetes secrets after Operator updates the service account (Issue #444).

Enhancements:

• Kubernetes: Added support for Kubernetes 1.19
• Kubernetes: Updated CSI sidecars to newest major versions.
• Switched to distroless for base-image, reducing size and attack surface.
• Added qtreesPerFlexvol option to allow customizing the number of qtrees per FlexVol in the ontap-nas-economy driver.
• Kubernetes: Added support for WaitForFirstConsumer via CSI-topology (Issue #405).
• Added requestID fields to most log statements to assist in following individual request through Trident.
• Kubernetes Trident can now send its logs to NetApp Autosupport Telemetry.
• Added support for storage volume labels in ANF, AWS, and GCP backends.

Beta Features:
These should not be used in production scenarios and are for testing and preview purposes only.

• Kubernetes: Automatic node preparation for NFS and iSCSI protocols. Trident can now attempt to make sure NFS and/or iSCSI packages and services are installed and running the first time an NFS or iSCSI volume is mounted on a worker node. Can be enabled with --enable-node-prep installation option.
• Added support for the default CVS service type on GCP.

Deprecations:

• Kubernetes: Removed etcd support, including ability to upgrade directly from etcd-based Trident (v19.04.1 or older).
