Abstract
Embodiments of the present disclosure provide methods, apparatuses, a system and computer program products for managing storage units. According to embodiments of the present disclosure, it is determined whether a first storage unit allocated at a first node is reclaimable, wherein data in the first storage unit is backed up to a second storage unit at a second node. In response to determining that the first storage unit is reclaimable, a condition to be satisfied for reclaiming the second storage unit is determined. A command indicating the condition is sent to the second node, such that the second node reclaims the second storage unit in response to the condition being satisfied. Moreover, in response to the command being sent, the first storage unit is reclaimed. The embodiments of the present disclosure enable timely reclaiming of storage units, thereby improving utilization of the storage space effectively.
