Abstract
Implementations of the present disclosure relate to a method, system and computer program product for managing a storage system. Specifically, in one implementation of the present disclosure there is provided a method for managing a storage system. The storage system comprises at least one stripe, a stripe of the at least one stripe comprising multiple extents among which respective extents being from respective storage devices in a resource pool. The method comprises: in response to receiving a converting request to convert the storage system from a first type to a second type, determining a target storage device associated with the converting request in the resource pool; for a stripe of the at least one stripe, updating metadata associated with the stripe so as to remove from the stripe an extent that is located at the target storage device; and converting the storage system from the first type to the second type on the basis of the updated metadata. In other implementations of the present disclosure, there is provided a corresponding system and computer program product.
