實驗原理：MFS是一個具有容錯性的網路分散式檔案系統，它把資料分散在多個物理伺服器上,而呈現給使用者的則是一個統一的資源。

實驗拓撲：192.168.80.181 Master server(主機名：www.aa.com)（元資料伺服器，在整個體系中負責管理檔案系統，維護元資料）

          192.168.80.182 Metlogger server (www.ab.com)（日誌伺服器，備份Master伺服器的變化日誌檔案，當Master伺服器資料丟失損壞時從這裡取得檔案進行恢復）

          192.168.80.183 Client (www.ac.com)

          192.168.80.184 Chunk server1 (www.ad.com) （真正儲存資料的伺服器）

          192.168.80.185 Chunk server2 (www.ae.com)
