通过之前的努力，已经搭建好了一套基本的tfs环境，包括一台nameserver和一台dataserver以及独立的nginx-tfs，而在实际应用中的分布式文件系统，只有一台dataserver明显是不行的，因而本文将介绍tfs环境下添加data server的操作和配置过程。
环境介绍：
Tfs nameserver服务器IP: 192.168.1.225
Tfs dataserver服务器IP: 192.168.1.227
新增tfs dataserver服务器IP：192.168.1.228
Nginx tfs服务器IP：192.168.1.12
一：228服务器上安装tfs软件，修改配置文件

227服务器：
# cd /usr/local/
# tar -zcvpf tfs.tgz tfs/
# scp tfs.tgz 192.168.1.228:/usr/local/
228服务器：
# cd /usr/local/
# tar -zxvpf tfs.tgz
# cd tfs
# rm -rf dataserver_*
# df -h |grep data

二：对磁盘进行初始化，启动dataserver服务

# cd /usr/local/tfs/scripts/
# sh stfs format 1-3
# df -h |grep data
|

|
# sh tfs start_ds 1-3
dataserver 1 is up SUCCESSFULLY pid: 29264
dataserver 2 is up SUCCESSFULLY pid: 29290
dataserver 3 is up SUCCESSFULLY pid: 29309
# netstat -ntpl |grep data
|
三： 查看添加是否成功，修改nameserver replicate为2

Name server服务器
# grep ‘replication‘ /usr/local/tfs/conf/ns.conf
max_replication = 2
min_replication = 2
# /usr/local/tfs/scripts/tfs stop_ns
nameserver exit SUCCESSFULLY
# /usr/local/tfs/scripts/tfs start_ns
nameserver is up SUCCESSFULLY pid: 12037
# /usr/local/tfs/bin/ssm -s 192.168.1.225:8108
show > machine -a
|
# /usr/local/tfs/bin/ssm -s 192.168.1.225:8108 -i show server
# tail -f /usr/local/tfs/logs/nameserver.log
四：上传，读取测试，可以看到shadow文件存储到了228上
