*修改/etc/hosts添加:(mfsmaster IP)
192.168.2.241          mfsmaster

啟動出錯：[root@localhost etc]# /usr/mfs/sbin/mfsmaster start
 working directory: /usr/mfs/var/mfs
 lockfile created and locked
 initializing mfsmaster modules ...
 loading sessions ... file not found
 if it is not fresh installation then you have to restart all active mounts !!!
 exports file has been loaded
 loading metadata ...
 can't open metadata file
 if this is new instalation then rename /usr/mfs/var/mfs/metadata.mfs.empty as /usr/mfs/var/mfs/metadata.mfs
 init: file system manager failed !!!
 error occured during initialization - exiting
修改：[root@localhost etc]# cd /usr/mfs/var/mfs
      [root@localhost mfs]# mv metadata.mfs.empty metadata.mfs

啟動成功：[root@localhost mfs]# /usr/mfs/sbin/mfsmaster start

master <-> metaloggers module: listen on *:9419
master <-> chunkservers module: listen on *:9420
main master server module: listen on *:9421
mfsmaster daemon initialized properly

*啟動metalogger:

/usr/mfs/sbin/mfsmetalogger start

*關閉metalogger:
/usr/local/mfs/sbin/mfsmetalogger stop

註：metalogger串連master的9419連接埠，注意Firewall把連接埠開啟，我在做測試時把iptables 關閉了.當master server出現故障需要恢複時可以從metalogger server 複製metadata.mfs.back 和最後一個日誌，缺一不可.

啟動mfs web gui:
[root@mfsmaster ~]# /usr/mfs/sbin/mfscgiserv
starting simple cgi server (host: any , port: 9425 , rootpath: /usr/local/share/mfscgi)

關閉mfs web gui:
kill /usr/mfs/sbin/mfscgiserv
