v3.3.0

Release Summary

🎉 🎉 🎉 OpenEBS 3.3 is another maintenance release focused on code, tests and build refactoring along with some critical bug fixes and user enhancements. This release includes fixes for user-reported critical bugs as well as fixes and enhancements to improve the E2e test coverage.

Deprecation Notice: Jiva and cStor out-of-tree external provisioners are deprecated now 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.

Upgrade and Backward Incompatibilities

Please review this list prior to deciding to upgrade:

  • Kubernetes 1.18 or higher release is recommended as this release uses features of Kubernetes that will not be compatible with older Kubernetes releases. Some of the engines might require you to have a higher Kubernetes version as the CSI drivers have been upgraded to the latest versions. For example, Kubernetes 1.19.12 or higher is recommended for using Rawfile Local PV.
  • 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.
  • The non-csi provisioners for cstor and jiva are not included by default with 3.0 helm chart or operator.yaml. You can still continue to use them. The older provisioners are released with the v2.12.2 version at the moment and only patch releases (to fix severe security vulnerabilities) will be supported going forward. If you need help making a decision on upgrading or migrating, please reach out to us on our Kubernetes Community slack channel #openebs.

v3.0.0

Release Summary

🎉 🎉 🎉 OpenEBS 3.0 is a culmination of efforts geared towards laying the foundation for making it easier to onboard and accept community contributions, making each of the data engine operators ready for future Kubernetes releases, making it easy to manage, and troubleshoot various data engines. This has been achieved via migration to the latest Kubernetes constructs, ease of use improvements, bug fixes and most importantly refactoring the control plane and e2e test suites to independently enhance and release each of the engines.

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.

Here is a quick summary of what has changed since the last release.

  • Added support for pushing the container images to GHCR, in addition to pushing the to DockerHub and Quay.io.
  • Rename the branches to "develop" or "main" on all the active repositories which are accepting contributions.
  • Update the CRD references to v1 across all components - even with deprecated provisioners - so users can continue to use the older provisioners beyond 1.22 as well.
  • Update the Kubernetes CSI driver side-cars to the latest version compatible with Kubernetes 1.18 and higher.
  • Enhance the iSCSI Targets functionality in Jiva and cStor volumes to only accept connections from one node at a time. The connection from a new node will be accepted only after the previous connection is torn down.
  • Enhanced the Local PV hostpath with a feature to enforce capacity limits using XFS quota - for volumes provisioned on XFS filesystem.
  • Enhanced the Jiva Specs (Jiva Volume Policy) to remove unused fields and make most of the fields with default configuration as optional. Also fixed the issues around specifying pod affinity and anti-affinity policies on jiva replica and target.
  • Enhanced the NDM operator and helm chart to include NDM exporter.
  • Enhanced NDM to detect filesystem and size changes, and update the block device resource. (under feature-gate in this release).
  • Dashboard and CLI have made enhanced their support to display details about cStor, Jiva, ZFS, LVM and Device Local PV.
  • Enhanced OpenEBS helm chart that can easily enable or disable a data engine of choice. The 3.0 helm chart stops installing the legacy cstor and jiva provisioners. If you would like to continue to use them, you have to set the flag “legacy.enabled=true”.
  • OpenEBS helm chart includes sample kyverno policies that can be used as an option for PodSecurityPolicies(PSP) replacement.
  • New revamped website for https://openebs.io is live.

v2.11.0

Release Summary

OpenEBS v2.11 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

  • Enhanced CLI to provide additional information about OpenEBS storage components like:
    • Block devices managed by OpenEBS (kubectl openebs get bd)
    • Jiva Volumes
    • LVM Local PV Volumes
    • ZFS Local PV Volumes
  • Added a new Stateful workload dashboard to Monitoring helm chart to display the CPU, RAM and Filesystem stats of a given Pod. This dashboard currently supports fetching details for LVM Local PV. In addition new alert rules related to PVC status are supported.
  • Enhanced LVM Local PV snapshot support by allowing users to configure the size that should be reserved for LVM snapshots. By default, the size reserved for a snapshot is equal to the size of the volume. In cases, where snapshots are created for backup purposes, the snapshots may not require the entire space. This feature helps in creating snapshots on VGs that don't have enough space to reserve full capacity for snapshots.
  • Enhanced the way custom topology keys can be specified for LVM Local PV. Prior to this enhancement, LVM driver would load the topology keys from node labels and cache them and if someone modified the labels and missed to restart the driver pods, there could be an impact to volume scheduling. This enhancement requires users to specify the topology key via ENV allowing users to know the current key and if there is a change, requires for a ENV modification that will force a restart of all the drivers.
  • NFS Provisioner has been updated with several new features like:
    • Ability to configure the LeaseTime and GraceTime for the NFS server to tune the restart times
    • Added a prometheus metrics end point to report volume creation and failure events
    • Added a configuration option to allow users to specify the GUID to set on the NFS server to allow non-root applications to access NFS share
    • Allow specifying a different namespace than provisioner namespace to create NFS volume related objects
    • Allow specifying the node affinity for NFS server deployment
  • Rawfile Local PV has been enhanced to support xfs filesystem.
  • Enhanced Jiva and cStor CSI drivers to handle split brain condition that could cause the Kubelet to attach the volume on new node while still mounted on disconnected node. The CSI drivers have been enhanced to allow iSCSI login connection only from one node at any given time.

Key Bug Fixes

  • Fixed an issue in Jiva Volume Replica STS keeps crashing due to change in the cluster domain and failed attempts to access the controller.
  • Fixed an issue in Jiva Volume that was causing log flooding while fetching volume status using Service DNS. Switched to using controller IP.
  • Fixed an issue in ZFS Local Volumes that was causing an intermittent crash of controller pod due erroneously accessing a variable.
  • Fixed an issue in Device Local PV causing a crash due to a race condition between creating partition and clearing a partition.
  • Several usability fixes to documentation and helm charts for various engines.

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.
  • Kubernetes 1.19.12 or higher is recommended for using Rawfile Local PV.
  • 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.

v2.10.0

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.

New Capabilities

  • kubectl plugin for openebs to help manage OpenEBS components. This release includes support for displaying details about:
    • cStor Pools and volumes,
    • Jiva Volumes.
  • OpenEBS monitoring add-on A set of Grafana dashboards and Prometheus alerts for OpenEBS, packaged as helm chart. This release includes support for:
    • cStor overview dashboard
    • cStor Pools, Replicas and Volumes Dashboard
    • Jiva Volume Dashboard
    • Alerts for Volume crossing capacity threshold

A very special thanks to @cncf and 2021 LFX Mentees @ParthS007, @rahul799 for contributing to the above features!!

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-archive/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.

v2.9.0

Release Summary

OpenEBS v2.9 is another maintenance release before moving towards 3.0 primarily focusing on enhancing the E2e tests and build/release workflows. This release includes fixes for user-reported critical bugs as well as fixes and enhancements to improve the E2e test coverage. There has been some significant progress made on the alpha features as well.

Key Improvements

  • Enhanced ZFS Local PV to use a custom node label called openebs.io/nodeid to set the node affinity for the provisioned volume. By default, the value will be the same as kubernetes.io/hostname. Using a custom label like this will help in quickly migrating the volumes to a new node in cases where a node fails and the user needs to move the underlying disks to a new node in the cluster. After moving the disks, the user can set the openebs.io/nodeid with the value used in the previous node. (openebs/zfs-localpv#304). You can read more about this feature here.
  • Enhanced cStor Velero plugin to allow users to specify a custom timeout for completing snapshot operations. The timeout can be configured via the restApiTimeout field in VolumeSnapshotLocation. See example. (openebs/velero-plugin#148)
  • Added helm chart for LVM Local PV.
  • Enhanced LVM Local PV to allow users to specify a pattern string of volume groups from which LVM Local PV should be provisioned. This feature will help in cases where a node can have multiple volume groups or volume group names across the cluster have to be unique. (openebs/lvm-localpv#28)

Key Bug Fixes

  • [cStor] Fixed an issue where helm chart pre-delete webhook was using a deprecated hyperkube image. Moved to kubectl images from bitnami. (#3383)
  • [cStor] Fixed an issue where some of the cStor operators were using deprecated ubuntu 16.04 as the base image. Moved to ubuntu 18.04.(#3386)
  • 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, out of which 50+ were accepted.

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.

Kubernetes volumes can be provisioned via CSI Drivers or using Out-of-tree Provisioners. The status of the various components as of v2.9.0 are as follows:

Alpha Feature Updates

  • Dynamic NFS Provisioner
    • Multi-arch container images with support for amd64, arm64, arm, and ppc64le
    • Helm chart
  • CSI Driver for Local PV Partitions
    • Support Creation and Deletion of a Local PV - by creating a partition of the requested capacity on local block devices.
  • openebsctl
    • Refactor the CLI to support APP VERB NOUN format. Example: kubectl openebs describe volume [cstor-pv-name]
    • Added support for kubectl openebs get pools
  • Monitoring-addon
    • Helm chart for setting up Prometheus operator with support for monitoring cStor pools
    • The sample dashboards will be moved to this add-on in the upcoming releases.

Other notable updates

  • OpenEBS has applied for becoming a CNCF incubation project and is currently undergoing a Storage TAG review of the project and addressing the review comment provided. One of the significant efforts we are taking in this direction is to upstream the changes done in uZFS to OpenZFS.
  • Migrated the CI pipelines from Travis to GitHub actions. (#3352)
