The techniques including a method comprising calculating an estimated time to storage fullness for respective storage pools in a space balance group, the estimated time to storage fullness based on an allocation speed of the respective storage pools. The method further comprises classifying a first storage pool having a first estimated time to storage fullness below a migration time threshold as a first migration source storage pool. The method further comprises classifying a second storage pool having a second estimated time to storage fullness above the migration time threshold as a first migration target storage pool. The method further comprises rebalancing free space in the space balance group by migrating storage volumes from the first migration source storage pool to the first migration target storage pool.
