Abstract
A computer-implemented method for reclaiming storage space on striped volumes may include: 1) identifying a volume striped across a set of storage devices, 2) identifying a reclamation request to reclaim storage space allocated to the striped volume and then, for at least one device in the set of storage devices, 3) identifying stripes of storage on the device that are covered by the reclamation request, 4) creating a consolidated reclamation request for the device that identifies each stripe of storage on the device that is covered by the reclamation request, and then 5) issuing the consolidated reclamation request to the device. Various other methods, systems, and computer-readable media are also disclosed.
