AliEnFS - A Linux File System for the AliEn Grid Services
Overview Among the services offered by the AliEn (ALICE Environment) Grid framework there is a virtual file catalogue to allow transparent access to distributed data-sets using various file transfer protocols. AliEnFS (AliEn File System) integrates the AliEn file catalogue as a new file system type into the Linux kernel using LUFS, a hybrid user space file system framework (Open Source). LUFS uses a special kernel interface level called VFS (Virtual File System Switch) to communicate via a generalised file system interface to the AliEn file system daemon. The AliEn framework is used for authentication, catalogue browsing, file registration and read/write transfer operations. The paper discusses general aspects of Grid File Systems, the AliEn implementation and present and future developments for the AliEn Grid File System.
