A method for allocating non-conflicting inode numbers between files generated at a first location and files generated at another location is provided. The method includes providing an inode number allocation rule table indicating availability for assignment a plurality of inode number allocation rules associated with the first location and the another location, generating a fileset at the first location by assigning an available inode number allocation rule to the fileset, registering, in the inode number allocation rule table, information associated with the fileset, and generating a file at the first location by determining the fileset within which to generate the file; and allocating an inode number for the file based on the available inode number allocation rule assigned to the fileset.
