Organize metadata servers by using quorum system
Tzong-Jye Liu, Wei-Chan Wang, Chuan-Mu Tseng · 2011
It is very important to distribute requests of finding files and to avoid the crash of a single metadata server, so we use a few metadata servers to build a distributed file system. However, this method may cause the inconsistency among metadata and the difficulty of searching metadata. Therefore, we use the quorum system to organize the metadata servers into a distributed file system, and the loading of the file system will be shared on metadata servers as average as possible. Besides, the quorum system not only makes sure of the consistency among metadata but also makes metadata searched easily.
