A Share Quota Manager for the Public Administrations

Among the data center services that Lepida ScpA offers to the Public Administrations (PAs) of Emilia-Romagna Region, there is the Storage As A Service; in particular, a growing number of PAs is asking for NAS to use for file systems joined to their domain, that we erogate over shared hardware. However, on the storage in our possession only a storage administrator user has the permissions to manage the quotas on the shares; but a storage administrator, on the other hand, would see all the shares of the different PAs that have been allocated on that physical storage. We therefore decided to develop a layer capable of decoupling the users who could access the storage from the permissions necessary for managing the quotas, in order to allow each individual PA to manage independently the quota trees on their own shares; in this paper we describe the solution we have devised and implemented.
