Abstract:
1. A method to automatically manage storage space, the method comprising: storing, by a storage system, a plurality of volumes, wherein each volume has an autodelete policy and an autosize policy that are disabled and the policies are operable to be enabled for individual volumes; configuring, by the storage system, the autodelete policy and the autosize policy for the plurality of volumes, wherein the autodelete policy and the autosize policy for a volume are not dependent on the autodelete policies and the autosize policies for other volumes in the plurality of volumes, and wherein configuring the autodelete policy and the autosize policy for an individual volume comprises configuring a trigger value for the first policy and a trigger value for the second policy for each of the individual volume, wherein the trigger value for the first policy and the trigger value for the second policy for the individual volume are not dependent on the trigger values for first policies and second policies for other volumes in the plurality of volumes; determining that the trigger value for a first policy for the individual volume is reached; automatically initiating the first policy for the individual volume; determining that the first policy for the individual volume fails to reclaim a target amount of free space in the individual volume; automatically initiating the second policy for the individual volume in response to determining that the first policy for the individual volume fails to reclaim a target amount of free space; and notifying a user if the second policy for the individual volume fails to reclaim a target amount of free space in the individual volume.
