Notable Features

Ceph

  • Added a toolbox job for running a script with Ceph commands, similar to running commands in the Rook toolbox.

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.
  • OSD changes:
    • OSD on PVC now supports multipath device.
