Abstract
Example methods and systems are provided for storage reclamation from a distributed storage system in a virtualized computing environment. The method may comprise: detecting a request to reclaim a target address range associated with the distributed storage system; and mapping the target address range to multiple data chunks. The method may also comprise: in response to identifying a fully-reclaimable stripe spanning across the multiple storage resources, reclaiming particular data chunks associated with the fully-reclaimable stripe, and parity chunk(s) associated with the fully-reclaimable stripe.
