Prerequisites

To make sure you have a Kubernetes cluster that is ready for Rook, you can follow these instructions.
In order to configure the Ceph storage cluster, at least one of these local storage options are required:

  • Raw devices (no partitions or formatted filesystems)
    • This requires lvm2 to be installed on the host. To avoid this dependency, you can create a single full-disk partition on the disk (see below)
  • Raw partitions (no formatted filesystem)
  • Persistent Volumes available from a storage class in block mode
