Group based qos policies for volumes

A system comprising:

• a plurality of nodes of a storage cluster;
• each node having a processor coupled to one or more storage devices, the processor executing instructions configured to,
• organize a plurality of volumes as a management domain of a namespace in a database of the storage cluster, the management domain providing a level of indirection that allows automatic and atomic updates to the volumes of the namespace;
• apply attributes to the management domain, the attributes including performance settings of one or more quality of service (QoS) policies;
• modify the management domain to change the attributes applied to the management domain;
• change the attributes of each volume of the management domain in accordance with the level of indirection provided by the management domain;
• and
• distributing enforcement of the one or more QoS policies at a level of service for the volumes of the management domain.

A non-transitory computer readable medium having program instructions configured to:

• organize a plurality of volumes as a management domain of a namespace in a database of a storage cluster, the management domain providing a level of indirection that allows automatic and atomic updates to the volumes of the namespace;
• apply attributes to the management domain, the attributes including performance settings of one or more quality of service (QoS) policies;
• modify the management domain to change the attributes applied to the management domain;
• change the attributes of each volume of the management domain in accordance with the level of indirection provided by the management domain;
• and
• distribute enforcement of the one or more QoS policies at a level of service for the volumes of the management domain.
