Abstract
Techniques are provided for scheduling storage volume migrations based on storage volume priorities and specified constraints. One method comprises generating a migratable volume list indicating storage volumes that can be migrated by evaluating available storage volumes according to an assigned priority and adding a storage volume to the migratable volume list in response to one or more constraints being satisfied that limit a migration of one or more of the storage volumes; and scheduling a migration of a volume part of a given storage volume from the migratable volume list based at least in part on a reevaluation of one or more of the constraints. The migratable volume list can be sorted by the assigned priority for each of the storage volumes. The migratable volume list can be regenerated in response to an event occurring that modifies the migratable volume list.
