v1.19 Pending Release Notes

Breaking Changes

• The minimum supported Kubernetes version is v1.30.

• The minimum supported Ceph version is v19.2.0. Rook v1.18 clusters running Ceph v18 must upgrade to Ceph v19.2.0 or higher before upgrading Rook.

• The behavior of the activeStandby property in the CephFilesystem CRD has changed. When set to false, the standby MDS daemon deployment will be scaled down and removed, rather than only disabling the standby cache while the daemon remains running.

• Helm: The rook-ceph-cluster chart has changed where the Ceph image is defined, to allow separate settings for the repository and tag. For more info, see the Rook upgrade guide.

• In external mode CephClusters when users give a Ceph admin keyring to Rook, Rook will no longer create CSI Ceph clients itself. This makes it so that all external mode clusters are managed via the same mechanism (external Python script) and avoids duplicate logic issues.

Features

• Experimental: Allow concurrent reconciles of the CephCluster CR when there multiple clusters being managed by the same Rook operator. Concurrency is enabled by increasing the operator setting ROOK_RECONCILE_CONCURRENT_CLUSTERS to a value greater than 1.
• Improved logging with namespaced names for the controllers for more consistency in troubleshooting the rook operator log.
