Claim 15:
16. A non-transitory machine-readable medium having stored thereon instructions for performing a method comprising machine-executable code which, when executed by at least one machine, causes the at least one machine to:
perform a plurality of reading operations and writing operations with respect to a storage node 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 storage node 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;
monitor the storage node for at least one of an activation event or a trigger event corresponding to a first volume of the plurality of volumes, the activation event comprising an incoming client request corresponding to when the first volume is in the passive mode, and the trigger event corresponding to when the first volume is in the active mode and comprising at least one of an activity score dropping below a first threshold, a number of the plurality of volumes exceeding a second threshold, or the first volume being inactive for more than a preselected period of time; and
adjust the first number of the plurality of volumes and the second number of the plurality of volumes by changing the first volume between the active mode and the passive mode based on detecting the activation event or trigger event.
