Describe the solution you'd like
Storage capacity tracking is an optional feature that is GA from Kubernetes v1.24. This feature helps the scheduler to schedule the pod on a node (satisfying the topology constraints) only if the requested capacity is available on the storage array. If none of the nodes can provide the storage space required by pod, the pods remain in pending state and are not scheduled randomly.
Additional context
With storage capacity tracking, the Pods get scheduling only when the capacity is available on a node, with topology constraints. If such a node is not available, the Pods stay in Pending state, i.e, not scheduled.
