Abstract
A computer-implemented method for reclaiming storage space from deleted volumes on thin-provisioned disks may include: 1) identifying a deleted volume, 2) identifying storage space on a thin-provisioned disk that was allocated to the deleted volume, 3) saving information that identifies the storage space, 4) identifying a policy that specifies reclaiming the storage space asynchronously with respect to the deleted volume, and then 5) reclaiming the storage space asynchronously with respect to deletion of the volume in accordance with the policy. Various other methods, systems, and computer-readable media are also disclosed.
