Zusammenfassung:One embodiment provides a method for storage management in an aggregated file system. The method includes tracking inode numbers for sub-file systems of the aggregated file system. A request for a unique range of inode numbers in the aggregated file system is received. The unique range of inode numbers is provided to one or more sub-file systems of the aggregated file system while providing that each sub-file system of the aggregated file system has a required range of inode numbers and that no two sub-file systems have overlapping inode numbers.
