This Roadmap defines OpenEBS features and capabilities that are in current development and may be included in upcoming releases.
Community and contributor involvement is vital for successfully implementing all desired items for each release. We hope that the items listed below will inspire further engagement from the community to keep OpenEBS progressing and shipping exciting and valuable features.
OpenEBS follows a lean project management approach by splitting the development items into current, near term and future categories.
This table holds a list of the most active roadmap items. These are the features that are currently getting the most active focus and attention within the project.
These are backlog items that are prioritized and planned to be completed within the next major release. While many are planned items, higher priority is given to usability, stability, resilience, Data integrity issues reported by the community.
Note: OpenEBS follows an aggressive release cadence with a new minor release every 2 months. For the most current plan and status check out the release project trackers. This document is reviewed and updated by the maintainers after each major release.
- Forward facing planned release date, Release version numbers and feature priorities are subject to change as the project Maintainers/Leadership/community continuously update and adjust the Release Feature bundling Strategy to react to K8s industry movements, trends and our community influence.

The Roadmap is focused exclusively on the modern *Mayastor Data-Engines in the STANDARD edition.
It does not define any net-new features or capabilities for any OpenEBS LEGACY projects or projects that are tagged & defined as DEPRECATED or ARCHIVED. (Currently those projects are as follows):
ID | Data-Engines | Embedded tech stack | Status |
---|---|---|---|
1 | Jiva | iSCSI | We plan to ARCHIVE & sunset LEGACY in 2024 |
2 | cStor | Open ZFS | We plan to ARCHIVE & sunset LEGACY in 2024 |
2 | NFS Provisioner | NFS userspace server | We plan to ARCHIVE & sunset LEGACY in 2024 |
These repos are critically required for the current roadmap.

Backlogs
- Shared VG for LVM Local PV.
- New set of items to be updated Feb 2024
- Support for hot upgrade, business continuity with no downtime.
- Support for volume groups, i.e. Mayastor replica placement should be topology aware for statefulsets zonal (or HA) distribution.

- Backlogs
- Upstream uZFS changes and start using them instead of a local fork
Typically the items under this category fall under next major release.
- Support for pluggable storage backend for Mayastor (example: replace blobstore with lvm)
- Support for specifying multiple hostpaths to be used with Local PV hostpath
- Update user documentation with reference stacks of running various workloads using OpenEBS volumes
- Auto provisioning of block devices (on the external storage systems) that can be used with OpenEBS storage engines
- Automate the workflows around handling scenarios like complete cluster failures that currently require some manual steps
- Custom Kubernetes storage schedulers to address auto-rebalancing of the data placed on the nodes to help with scale up/down of Kubernetes nodes
- Support for restoring a volume (in-place) for supporting blue/green stateful deployments
- Partial rebuild for the Mayastor replicas (similar to zfs resilvering)
- Support Bulk BDC requests to claim multiple block devices that satisfy affinity or anti-affinity rules of applications. Example: two block devices from same node or two block devices from different nodes.
- Support for device configuration tasks like partitioning, mounting or unmounting devices by adding new services via NDM gRPC API layer.
As the name suggests this bucket contains items that are planned for future. Sometimes the items are related to adapting to the changes coming in the Kubernetes repo or other related projects. Github milestone called future backlog is used to track these requests.
