After troubleshoot a lot, i found some useful info about DeDuplication problems. So i am going to explain each and every stuff about his issue.

Information about Servers and Folder :

I have two server FS01 and FS02.

Each server has 3 SAN Volumes. (E.g. Users, Public, Work)

Three DFS Namespaces \mydoamin.net\Users\India, \mydoamin.net\Users\Public and \mydoamin.net\Users\Work

Deduplication is enabled on all three volumes.
All users hits FS02 to access Public drive, FS01 Public is just for backup.

Verify & Repair Permissions - El Capitan

As you all know, Apple has removed this feature in new OS X El Capitan. But if you have Macbooks or Macmini in your office and using them on enterprise level infrastructure. It could be a bad news for you because in many cases and troubleshooting we use "Repair Disk Permissions".

So open up your Terminal.app and use below mentioned commands to Verify and Repair Disk Permissions.

sudo /usr/libexec/repair_packages --verify --standard-pkgs /

To Repair, Please use the below mentioned code.

sudo /usr/libexec/repair_packages --repair --standard-pkgs --volume /
