A method generates a graphical portion of a graphical user interface (GUI), the graphical portion concerning aspects of a storage domain. Such a method may include: illustrating a tree hierarchy; including, on the tree hierarchy, a node at a first level corresponding to a set of at least two file systems that are members of the storage domain; and including, on the tree hierarchy, nodes at a second level reporting to the first-level node, each second-level node corresponding to a member of the set of files systems to which the first node corresponds. Related apparatus and machine-readable media having instructions can each include features similar to elements of the method.
