1. A method for implementing write-once-read-many (WORM) storage system having a file system comprising the steps of: issuing a WORM volume create command to create a designated WORM volume among a set of disks; creating a WORM file and saving the WORM file to the WORM volume; and committing the WORM file to the WORM volume by transitioning a WORM file attribute to transition the file from a not-read-only to read-only state, wherein the file system recognizes the read-only file attribute as designating a WORM file in the WORM volume.
