Release Summary

OpenEBS v2.10 is another maintenance release before moving towards 3.0 primarily focusing on enhancing the E2e tests, build, release workflows, and documentation. This release also includes enhancements to improve the user experience and fixes for bugs reported by users and E2e tools. There has been some significant progress made on the alpha features as well.


Deprecation Notice: Jiva and cStor out-of-tree external provisioners will be deprecated by Dec 2021 in favor of the corresponding CSI Drivers. The out of tree provisioners for Jiva and cStor will stop working from Kubernetes 1.22 and forward as the version of the custom resources used by those provisioners will be deprecated. We strongly recommend you plan for migrating your volumes to cStor CSI or Jiva CSI as early as possible.

If you have any questions or need help with the migration please reach out to us on our Kubernetes Community slack channel #openebs.

Key Improvements

Key Bug Fixes

  • [Local PV] Fixed an issue in CSI Controllers of LVM Local PV and Device Local PV that could potentially cause stale Volume custom resources to be created in cases where PVC gets deleted prior to completion of the create volume request. openebs/lib-csi#11
  • [Dynamic NFS] Fixed an issue with Liveness probe in the NFS provisioner. openebs/dynamic-nfs-provisioner#41
  • Several fixes to docs were also included in this release.
  • OpenEBS participated in the CNCF BugBash program in KubeCon EU 2021 and has received more than 90 PRs. This release includes several PRs from the program that were accepted after the 2.9 release.

Backward Incompatibilities

  • Kubernetes 1.18 or higher release is recommended as this release uses features of Kubernetes that will not be compatible with older Kubernetes releases.
  • OpenEBS has deprecated arch-specific container images in favor of multi-arch container images. For example, images like cstor-pool-arm64:x.y.x should be replaced with corresponding multi-arch image cstor-pool:x.y.x.
