DFS Distributed File system

DFS: Distributed File System
Function:
1. Centralize shared folders across multiple computers into one virtual shared folder for user access and use
2. Many services require a high availability of shared folders. such as: Cluster as arbitration

Terms:
Namespace: is a set of virtual views of a shared folder in DFS.

(When the client accesses the DFS server, the \\geng.com\dfsroot is entered, and this virtual view is the namespace)

Namespace servers: Computers that host namespaces

(The server responsible for consolidating the scattered folders into a virtual directory.) ）

Folder: The folder of the namespace

(folder under command space)

Folder target: The actual target of the folder

(The true path of the folder)

Experimental environment: SERVER01 domain control, SERVER02, SERVER03 are member servers.

Example: Deploying a Dfs File system to consolidate shared folder information on multiple servers

Step 1: Install the DFS component

Step 2: Open the DFS management tool

Server Manager--dfs Mange

Command space--right--Create a new namespace

650) this.width=650; "title=" image "style=" border-top:0px; border-right:0px; Background-image:none; border-bottom:0px; padding-top:0px; padding-left:0px; border-left:0px; padding-right:0px "border=" 0 "alt=" image "src=" http://s3.51cto.com/wyfs02/M00/6E/37/ Wkiol1v2tvqimsgvaadnybvjwak251.jpg "" 591 "height=" 217 "/>

Choose which server to do the namespace server, the experiment is SERVER01 do DFS server

650) this.width=650; "title=" image "style=" border-top:0px; border-right:0px; Background-image:none; border-bottom:0px; padding-top:0px; padding-left:0px; border-left:0px; padding-right:0px "border=" 0 "alt=" image "src=" http://s3.51cto.com/wyfs02/M01/6E/37/ Wkiol1v2tvriyxihaadrnnhdc7o655.jpg "" 591 "height=" 437 "/>

Name of the namespace

650) this.width=650; "title=" image "style=" border-top:0px; border-right:0px; Background-image:none; border-bottom:0px; padding-top:0px; padding-left:0px; border-left:0px; padding-right:0px "border=" 0 "alt=" image "src=" Http://s3.51cto.com/wyfs02/M01/6E/37/wKioL1V2tVrDuibAAAE6Pw_ Jx3e767.jpg "" 594 "height=" 442 "/>

The edit settings, mainly the right to edit the shared folder of the namespace, here we select the default all user access has Read permission

650) this.width=650; "title=" image "style=" border-top:0px; border-right:0px; Background-image:none; border-bottom:0px; padding-top:0px; padding-left:0px; border-left:0px; padding-right:0px "border=" 0 "alt=" image "src=" http://s3.51cto.com/wyfs02/M02/6E/3B/ Wkiom1v2s7ejd8m1aafkmxxa36s657.jpg "" 493 "height=" 545 "/>

Select a domain namespace

In a domain environment, it is recommended to select a namespace for the domain, and multiple namespaces can be established to facilitate troubleshooting or high availability

Stand-alone namespaces: only one namespace

650) this.width=650; "title=" image "style=" border-top:0px; border-right:0px; Background-image:none; border-bottom:0px; padding-top:0px; padding-left:0px; border-left:0px; padding-right:0px "border=" 0 "alt=" image "src=" http://s3.51cto.com/wyfs02/M00/6E/3B/ Wkiom1v2s7einzmdaagksm84jfe438.jpg "" 591 "height=" 437 "/>

Server02 display folder, the shared folder will appear on the Server02

650) this.width=650; "title=" image "style=" border-top:0px; border-right:0px; Background-image:none; border-bottom:0px; padding-top:0px; padding-left:0px; border-left:0px; padding-right:0px "border=" 0 "alt=" image "src=" http://s3.51cto.com/wyfs02/M00/6E/3B/ Wkiom1v2s7js0r5kaaengkv3h6g382.jpg "" 570 "height=" 520 "/>

A folder on the namespace is created

650) this.width=650; "title=" image "style=" border-top:0px; border-right:0px; Background-image:none; border-bottom:0px; padding-top:0px; padding-left:0px; border-left:0px; padding-right:0px "border=" 0 "alt=" image "src=" http://s3.51cto.com/wyfs02/M01/6E/3B/ Wkiom1v2s7jcbruraadtegizpwi360.jpg "" 574 "height=" 237 "/>

Step 4: Test

Access on the Server02

650) this.width=650; "title=" image "style=" border-top:0px; border-right:0px; Background-image:none; border-bottom:0px; padding-top:0px; padding-left:0px; border-left:0px; padding-right:0px "border=" 0 "alt=" image "src=" http://s3.51cto.com/wyfs02/M02/6E/3B/ Wkiom1v2s7iy6cqiaafb-4qrxai168.jpg "" 578 "height=" 356 "/>

Experimental success

Instance: namespace server High Availability

Role: Prevent server failure causing shared folder access to fail

Experimental ideas: High availability of namespaces between Server01 and Server02

1: First: Install the DFS component on Server02

2:server01 Open DFS Management--geng.com\dfsroot--right--Add a namespace server

650) this.width=650; "title=" image "style=" border-top:0px; border-right:0px; Background-image:none; border-bottom:0px; padding-top:0px; padding-left:0px; border-left:0px; padding-right:0px "border=" 0 "alt=" image "src=" http://s3.51cto.com/wyfs02/M01/6E/3B/ Wkiom1v2s7mbuoqiaaeyceylfba823.jpg "" 584 "height="/>

Namespace server--Browse--SEVER02

At this point, 2 DFS default sites will appear on the namespace server

Example: High availability of folders, example of a game folder

Experimental purpose: Server02 and server03 on the shared folder game high availability

Step 1:server02: Click the game Folder--right--Add folder target

650) this.width=650; "title=" image "style=" border-top:0px; border-right:0px; Background-image:none; border-bottom:0px; padding-top:0px; padding-left:0px; border-left:0px; padding-right:0px "border=" 0 "alt=" image "src=" http://s3.51cto.com/wyfs02/M01/6E/3B/ Wkiom1v2s7nbdzxyaafdkier5hy963.jpg "" 629 "height=" 277 "/>

Folder destination path, choose to do a highly available DFS server, here is SERVER03

Browse

Server: server03--Show shared Folders

(The game folder is already shared on SERVER03)

650) this.width=650; "title=" image "style=" border-top:0px; border-right:0px; Background-image:none; border-bottom:0px; padding-top:0px; padding-left:0px; border-left:0px; padding-right:0px "border=" 0 "alt=" image "src=" http://s3.51cto.com/wyfs02/M00/6E/3B/ Wkiom1v2s7qgur6baadk3oseid8880.jpg "" 453 "height=" 418 "/>

Yes, this is to create a replication group that synchronizes the Server02 with file replication on SERVER03
