Major Themes

v1.5.0 is a minor release with features primarily for the Ceph operator.

Upgrade Guides

If you are running a previous Rook version, please see the corresponding storage provider upgrade guide:

The CRDs have been separated from common.yaml into crds.yaml to give more flexibility for upgrades. New non-helm deployments require installation of the crds.yaml.
The discovery daemon is disabled by default in new clusters since the discovery is not necessary in most clusters.
- Enable the discovery daemon if devices are being added to nodes and you want to automatically configure OSDs on new devices without restarting the operator.
Rook will now disallow an even number of Ceph mons. Mons require an odd number for a healthy quorum.
CRDs have been updated to use apiextensions.k8s.io/v1 Kubernetes API from the deprecated apiextensions.k8s.io/v1beta1.

Ceph Cluster
- The storage capacity of the cluster is updated periodically in the CephCluster CR status
- Encryption support is available with a Key Management Service (Vault)
- (experimental): Support for Stretch clusters that allow mons and OSDs to work reliably across two data centers
Ceph Block Pool
- Improved mirroring support for block pools
- New replicasPerFailureDomain setting to allow for a number of replicas in a secondary failure domain, primarily for stretch clusters
Ceph Filesystem
- preserveFilesystemOnDelete option replaces preservePoolsOnDelete to avoid deleting the filesystem during uninstall
  - Rook will treat the deprecated preservePoolsOnDelete: true as if the user intends preserveFilesystemOnDelete: true
Helm chart
- Updated to Helm v3.4 for build and testing
- Added a crds.enabled setting to allow the CRDs to be managed separately from the Helm chart. By default the CRDs are still installed
Ceph CSI
- Allow custom labels to be added to DaemonSet and Deployment Pods
