v19.01.0

Changes since v18.10.0

Fixes:

• Fixed an issue where Trident did not allow specifying a port in the management LIF config (Issue #195). Thank you, @vnandha!
• Only strip prefix on volume name if volume name starts with prefix.
• Kubernetes: Refactored BackendExternal which fixed the output of "tridentctl get backend -o json" where details like "limitAggregateUsage" and "limitVolumeSize" were not found. (Issue #188)

Enhancements:

• Updated Trident's 3rd-party dependencies for 19.01 release.
• Added support for Docker 18.09, Docker Enterprise Edition 2.1, OpenShift 3.11 and Kubernetes 1.13.
• Removed support for Docker Enterprise Edition 2.0 and Kubernetes 1.8.
• Kubernetes: Added support for raw block volumes for iSCSI PVs.
• Kubernetes: Added retry logic to installer for Kubernetes object creation.
• Kubernetes: Updated etcd to v3.3.10 and client-go to v10.0.0.
• Kubernetes: Trident now honors the nfsMountOptions parameter in ONTAP NAS backend config files.
• Behavioural change: The Trident installer now automatically adds the backend used to provision the Trident volume in new installations.

Deprecations:

• Kubernetes: Deprecated PVC annotation trident.netapp.io/reclaimPolicy as the reclaim policy can be set in the storage class since Kubernetes v1.8.

  will be deprecated and will not be needed in order to install or uninstall Trident.

v18.07.0

Changes since v18.04.0

Fixes:

• Fixed cleanup of the transaction object upon failed deletion (Issue #126).
• Kubernetes: Fixed an issue where Trident would provision a ReadWriteMany PVC to an iSCSI backend.
• Kubernetes: Fixed an installer issue where the Trident PV could be bound to the wrong PVC (Issue #120).

• Docker: Fixed an issue where deleted qtrees could appear in Docker volume list.
• Docker: Fixed plugin restart issue for newer versions of Docker (Issue #129).
• Docker: Trident no longer crashes if ONTAP volumes are offline (Issue #151).

Enhancements:

• Added ontap-nas-flexgroup driver to support ONTAP FlexGroup Volumes.
• Changed ONTAP drivers so that the snapshot reserve is set to zero when snapshotPolicy is "none".
• Added support for Docker EE UCP.
• Kubernetes: Added regex matching to storage pool selection as well as a new excludeStoragePools option for Kubernetes storage classes (Issue #118).
• Kubernetes: Added support for iSCSI multipath (Issue #69).
• Kubernetes: Updated etcd to v3.2.19 and client-go to v7.0.0.
• Kubernetes: Added --previous switch to 'tridentctl logs' command.

v18.04.0

Changes since v18.01.0

Fixes:

• Clone operations are more resilient to busy storage controllers.
• Fixed cleanup of goroutines.
• Extended timeouts for storage controller API invocations.
• Prevented exit if a startup error occurs so Docker and Kubernetes don't restart Trident continuously.
• Fixed an issue where SolidFire cloned volumes were not updated with new QoS values.
• Kubernetes: Trident no longer emits SCSI bus rescan errors into log.
• Kubernetes: Fixed incorrect association of volumes with backends after backend update (Issue #111).
• Docker: iSCSI device discovery and removal is faster, more granular, and more reliable.
• Docker: Fixed default size handling (Issue #102).
• Docker: Client interfaces start immediately to avoid Docker plugin timeouts.

Enhancements:

• Added FQDN support for the management and data LIF of ONTAP backends.
• For Kubernetes 1.9+, CHAP secrets will be created in Trident's namespace
  instead of the PVC's namespace.
• Return new HTTP codes from REST interface to indicate Trident startup status.
• Set the minimum supported SolidFire Element version to 8.0.
• Kubernetes: Simplified installing Trident with a new installer.
• Kubernetes: Added the ability to define a custom name for a storage
  backend. This enhancement enables adding multiple instances of the same
  backend with different policies (e.g., different snapshot policies), which
  obviates extending the Trident storage class API to support new parameters
  (Issue #93).
• Kubernetes: Added the ability to rename an existing backend.
• Kubernetes: SolidFire defaults to use CHAP if Kubernetes version is >= 1.7
  and a trident access group doesn't exist. Setting AccessGroup or UseCHAP in
  config overrides this behavior.
• Docker: The aggregate attribute in ONTAP config files is now optional.

v18.01.0

Changes since v17.10.0

Fixes:

• Volume deletion is an idempotent operation with the ontap-nas-economy driver (Issue #65).
• Enabled Trident installation on an EF-series (all-flash) array.
• Fixed an issue where qtrees with names near the 64-character limit could not
  be deleted.
• Enforced fencing of ONTAP aggregates and E-series pools to match config file values.
• Fixed an issue where deleting volumes using the ONTAP SAN driver could leave
  volumes stuck in a partially deleted state.
• Fixed an issue where the ONTAP SAN driver would create junction paths for cloned iSCSI volumes

Enhancements:

• Trident can now serve as a Docker Volume Plugin.
• Enabled cloning volumes via a new PVC annotation.
• Added support for Kubernetes 1.8 Storage Classes to set the mount options and reclaim policy of PVs (Issue #49).
• Introduced the fsType parameter in the Kubernetes Storage Class to set the file system type of iSCSI PVs.
• Added CHAP support for SolidFire (Issue #42).
• Decoupled Trident storage pools from volumes to facilitate "vol move" and SVM-DR with ONTAP backends.
• Added support for the etcdv3 API (Issue #45).
• Added the etcd-copy utility to migrate data between etcd clusters.
• Enabled TLS for Trident's etcd client and the etcd-copy utility.
• Added scripts and instructions for setting up an external etcd cluster using
  etcd operator.
• Significantly reduced Trident and Trident-Launcher Docker image sizes.
• Clarified and enhanced storage class pool selection by introducing storagePools and renaming
  requiredStorage to additionalStoragePools.
• Added hostname support to the dataLIF option in the config file for ontap-nas and ontap-nas-economy drivers.
• Added minimum volume size checks to all plugins.
• Docker: Improved iSCSI rescan performance for ONTAP SAN and E-series plugins.
