The present disclosure provides storage management systems and methods. A hierarchical configuration information process includes accessing information regarding hierarchical relationships of components associated with a storage environment. A storage resource consumption detection process includes detecting consumption of storage resources included in the storage environment. A coordinated consumption analysis process is coordinated across multiple levels of an active spindle hierarchy. A reaction process includes performing an automated consumption notification process and an automated reclamation process based upon results of the storage resource consumption detection process.

detecting a storage usage condition at an application level comprising at least a high storage pool utilization condition, wherein the storage usage condition further comprises at least an indication that a second amount of storage in use by the plurality of hosts may exceed the amount of storage allocated to the thin provision pool; and
notifying a user of the storage usage condition; and
performing a storage reclamation process comprising:
