Quality of service (QoS) setting recommendations for volumes across a cluster

A system, method, and machine-readable storage medium for providing a quality of service (QoS) recommendation to a client to modify a QoS setting are provided. In some embodiments, a set of volumes of a plurality of volumes may be determined. Each volume of the set of volumes may satisfy a first QoS setting assigned to the volume and a second QoS setting assigned to the volume. The plurality of volumes may reside in a common cluster and may be accessed by the client. Additionally, a subset of the set of volumes may be determined. Each volume of the subset may satisfy an upper bound of a range based on a minimum IOPS setting of the volume. A QoS recommendation to the client to modify the first QoS setting may be transmitted for one or more volumes of the subset.
