Claim 7:
8. A method comprising:
performing a plurality of reading operations and writing operations with respect to an aggregate that includes a first number of a plurality of volumes operating in an active mode, the active mode allowing both write activity and read activity, the aggregate further including a second number of the plurality of volumes operating in a passive mode, the passive mode allowing read activity and blocking write activity, wherein the second number of the volumes that operate in the passive mode consume fewer resources than the first number of the volumes that operates in the active mode;
generating an activity score corresponding to each volume of the plurality of volumes in the aggregate, wherein the activity score is based on input/output activity and internal activity of each respective volume; and
adjusting the first number of the plurality of volumes and the second number of the plurality of volumes, by changing a first volume of the plurality of volumes between the active mode and the passive mode based on the activity score of the first volume.
