Notable Features

Ceph

  • CephCluster CRD has been converted to use the controller-runtime framework.
  • CephBlockPool CRD has a new field called parameters which allows to set any property on a given pool
  • OSD changes:
    • OSD on PVC now supports multipath device.

Breaking Changes

Ceph

  • rbd-mirror daemons that were deployed through the CephCluster CR won't be managed anymore as they have their own CRD now. To transition, you can inject the new rbd mirror CR with the desired count of daemons and delete the previously managed rbd mirror deployments manually.
