摘要：

The efficiency of metadata indexing is important to the performance of distributed file system. Time and space spending of current metadata management algorithms are unstable. In this paper, we use B-tree to index the metadata of distributed file system. Lustre is an open source distributed file system in which Hash function is used to manage the metadata. We implement the prototype of metadata indexing sub-system on Lustre and use Iozone to test the I/O performance of Lustre with and without the metadata indexing sub-system respectively. The simulation results show that Lustre with the metadata indexing sub-system has higher adaptability than Lustre with Hash-based metadata management algorithm.
