Features in this release:

  • Upgrade support
    • Engine upgrade - Engine can be upgraded from v0.3 to v0.3+ without volume downtime. Upgrading from v0.2 to v0.3 would incur volume downtime.
    • Manager upgrade - Manager can be upgraded from previous release, with API downtime. No downtime for the Longhorn volumes (except from v0.2 to v0.3).
  • Container Storage Interface(CSI) - Support CSI as the Kubernetes storage driver for Kubernetes v1.10+. It will eventually replaced our Flexvolume driver in the future.
  • S3 backup target - Support S3 as the backup target.
  • iSCSI endpoint - Support iSCSI as an alternative volume frontend.
  • Base image - Support using RancherVM base image to be used as the base for the volume, so the user will able to start a VM using Longhorn volume as root image.
  • RancherVM live migration - Support RancherVM live migration with Longhorn volume as the root image.
  • Multiple disk with capacity based scheduling - User can update the node config and set desired disk (mounted to a node directory) to store Longhorn volume data. Longhorn can choose where to place the volume data depends on how much space the disk had left.
  • Websocket support - UI will get the up to date information without refreshing.
