Abstract: A user can set or modify operational parameters of a data volume stored on a network-accessible storage device in a data center. For example, the user may be provided access to a data volume and may request a modification to the operational parameters of the data volume. Instead of modifying the existing data volume, the data center can provision a new data volume and migrate data stored on the existing data volume to the new data volume. While the data migration takes place, the existing data volume may block input/output (I/O) requests and the new data volume may handle such requests instead. If a request is received for data not yet migrated to the new data volume, then the new data volume prioritizes a migration of the requested data.

While the data migration takes place, the existing data volume may block input/output (I/O) requests and the new data volume may handle such requests instead. Once the data migration is complete, the data center may deallocate the data blocks of the existing data volume such that the data blocks can be reused by other data volumes.

Abstract: A system and method for provisioning a volume and repartitioning a provisioned volume based at least in part on a workload. A request to provision a volume of a specified size is received, a first set of partition options is determined based at least in part on the specified size, and second set of partition options is determined based at least in part on one or more performance characteristics. A volume partitioning is determined based at least in part on an intersection of a number of partitions between the first set of partition options and the second set of partition options, and further based at least in part on a set of optimization criteria. Based at least in part on tracked usage of the volume or a repartition request, a determination is made to repartition the volume such that the partitioning scheme fulfills a set of optimization criteria.
