Abstract :
We introduce the design and implementation of DCFS (Dawning Cluster File System), a cluster file system developed for the Dawning4000 LINUX clusters. DCFS provides the single name space and binary compatibility with local file system for users and applications on Dawning4000. In addition, it improves system manageability for administrators by embedded file system management considerations into DCFS implementation and provides an easy use interface. Important features of DCFS are presented, including a global management domain, a communication abstraction layer, pipelined file I/O, enhanced multitask capability in storage servers, and fault-tolerance strategy.
