Abstract
The invention discloses a method for establishing a disk file system. The method comprises the following steps of: uniformly storing identifications corresponding to disk partitions needing to be managed into other disk partitions; orderly formatting the disk partitions corresponding to the stored identifications; allocating a superblock object for the disk file system in a memory; initializing device fields in the superblock object into a linked list; and after orderly saving superblock information of the uniformly managed disk partitions into the linked list, mounting the disk file system on a catalog. By using the method, when the space of a certain disk partition managed uniformly by the disk file system is not enough, a file can be saved in other uniformly managed disk partition without remodifying the catalog in which the file is saved; therefore, the method can ensure that the file is saved correctly and reduce the workload required for managing the file at the same time.
