Calculate total PersistentVolume capacity needed across all cluster claims.
Total PV capacity = sum of all PVC requests plus a buffer for growth. Formula: pool = PVCs × avgSize × (1 + overProvision%). Over-provisioning ensures new claims and volume expansions can be fulfilled without waiting for new storage.
PV Pool Size
pool = pvcCount × avgSize × (1 + overProvision%)
New PVCs will remain in Pending state until capacity is available. Dynamic provisioners may fail to create volumes, blocking pod scheduling.
Dynamic provisioning (via StorageClass) is preferred for most workloads — it automatically creates PVs on demand. Static provisioning is useful for pre-existing storage or special performance tiers.
