FILE SYSTEM CREATING AND DELETING APPARATUS AND DRIVING METHOD THEREOF

摘要

The purpose of an embodiment of the present invention is to provide a file system creating and deleting apparatus and a driving method thereof. The apparatus allocates an inode stored in an available inode pool when creating a file system object, and stores an inode retrieved upon a delete request of an available inode in the available inode pool when deleting a file system object. The file system creating and deleting apparatus according to an embodiment of the present invention includes: an available inode pool in which inodes are stored; a file system object creation processor for generating an inode allocation request signal in response to a file system creation request from the outside; an inode allocation processor for allocating at least one of inodes stored in the available inode pool in response to the inode allocation request signal; a file system object deletion processor for generating an inode release request signal in response to a file system deletion request from the outside; an inode deletion thread for collecting a delete-requested inode corresponding to the file system deletion request; and an inode release processor for releasing the delete-requested inode from the inode deletion thread, wherein the number of inodes stored in the available inode pool is limited to the maximum number of inodes of the available inode pool or smaller, and when the number of inodes stored in the available inode pool is smaller than the maximum number of inodes of the available inode pool, the delete-requested inode is stored in the available inode pool.
