Abstract: A method includes sending, by a computing device of a dispersed storage network (DSN), an inquiry to storage units of the DSN regarding status of a new vault in the DSN. The new vault is a logical storage container supported by the storage units, and the new vault is defined by vault parameters that include new vault identifier, new vault storage capabilities, access privileges, and authorized users.
