Most of large-scale distributed file systems decouple metadata operation from reading or writing operation for a file. In other words, certain servers named metadata server (MDS) is responsible for maintaining the metadata information of file systems. But, mostly the existing file systems are used a restrictive metadata management technique, because those systems mostly designed to focus a distributed management of data and an input/output performance rather than the metadata. In this paper, we present a new non-shared metadata management technique in order to provide flexible metadata throughput and scalability. First, we introduce a new metadata distribution technique called dictionary partitions (DP). Then, we introduce load distribution technique based DP. In addition, we demonstrate the superiority of our technique with shared metadata management technique.
