Usage of a storage volume is monitored, including monitoring a write frequency and an overwrite frequency for the storage volume. The overwrite frequency may be obtained from garbage collection data for the storage volume. The write frequency and overwrite frequency may be used to obtain a growth rate and predict future usage of the storage volume. Where future usage indicates that expansion of storage allocated to the storage volume is needed, affinity requirements, anti-affinity requirements, and rebalancing reduction are evaluated with respect to the expansion. If expansion satisfies these constraints, the storage volume is locally expanded. Otherwise, the storage volume is relocated to a different storage device.
