Rook - v1.13.0

Upgrade Guide

To upgrade from previous versions of Rook, see the Rook upgrade guide.

Breaking Changes

• Removed support for Ceph Pacific (v16). Ceph Quincy (v17) and Ceph Reef (v18) are the only currently supported versions.
• The minimum supported Kubernetes version is v1.23
• The minimum supported Ceph-CSI driver is 3.9
• The admission controller is removed. If the admission controller is enabled (it is disabled by default), it is recommended to be disabled before the upgrade. See the upgrade guide for more details.

Features

• Added experimental cephConfig to the CephCluster CR to allow setting Ceph config options in the Ceph MON config store via the CRD. These settings supersede the ceph.conf override settings.
• CephCSI v3.10 is now the default CSI driver version.
• Per-cluster CSI settings for read affinity moved from the operator configmap settings to the CephCluster CR
• The default CephFS SubvolumeGroup has pinning enabled by default to distribute load across MDS ranks in predictable and stable ways.
• The Ceph exporter daemon is updated to use a Ceph keyring with reduced privileges instead of the admin keyring.
• If the host network setting changes in the CephCluster CR, the mons will now automatically failover to enable the new configuration.
• Allow for additional advanced maintenance and troubleshooting of Ceph daemons, by respecting the label ceph.rook.io/do-not-reconcile for all Ceph daemons. This is helpful when using the debug command in the kubectl rook-ceph plugin.
