TFS增加dataserver

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

# grep -v '^#' /usr/local/tfs/conf/ds.conf |grep -v '^$'

[public]

log_size=1073741824

log_num = 16

log_level=info

task_max_queue_size = 10240

port = 9998

work_dir=/usr/local/tfs

dev_name= eth0

thread_count = 4

ip_addr = 192.168.1.228

[dataserver]

ip_addr = 192.168.1.225

ip_addr_list = 192.168.1.225|192.168.1.226

port = 8108

heart_interval = 2

check_interval = 2

replicate_threadcount = 2

block_max_size = 7549747

dump_visit_stat_interval = 60

backup_type = 1

backup_path = /data/tfs

mount_name = /tfs/data

mount_maxsize = 20971520

base_filesystem_type = 1

superblock_reserve = 0

avg_file_size = 40960

mainblock_size = 7549747

extblock_size = 419430

block_ratio = 0.5

hash_slot_ratio = 0.5

ds_thread_count = 4

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

1 2	`# /usr/local/tfs/bin/tfstool -s 192.168.1.225:8108` `TFS> put /etc/passwd`

1	`TFS> put /etc/shadow`
