TFS Add DataServer

With previous efforts, a basic set of TFS environments has been built, including a nameserver and a dataserver as well as a standalone nginx-tfs, while in real-world Distributed file systems, only one dataserver is obviously not working, Therefore, this article describes the Operations and configuration procedures for adding data server under the TFS environment.

Environment Introduction:

TFS nameserver Server ip:192.168.1.225

Tfs dataserver Server ip:192.168.1.227

New TFS dataserver server IP:192.168.1.228

Nginx TFS Server IP:192.168.1.12

One: install TFS Software on the 228 server , modify the configuration file

Second: Initialize the disk, start the dataserver service

123	# 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

Three: See if Add is successful, modify nameserver replicate to 2

Four: Upload, read the test, you can see the shadow file stored on 228
