k8s: Kubernetes v1.35: Mutable PersistentVolume Node Affinity (alpha)
Kubernetes Official Blog
2026-01-08
Kubernetes v1.35 (alpha) makes PersistentVolume.spec.nodeAffinity mutable. This allows administrators to update PV node affinity to match changes in underlying storage (for example zonal→regional migrations or disk-generation upgrades) without recreating the PV. The feature is gated (MutablePVNodeAffinity), disabled by default, and requires updating the storage provider first. Be aware of scheduling race conditions when tightening affinity; future kubelet/CSI integration and VolumeAttributesClass automation are planned. Feedback is requested via SIG Storage channels.
