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.
