Unable to create Secondary Zone on Linux Bind DNS

Question: Unable to create Secondary Zone on Linux Bind DNS

 Answer:

This problem appears if zone storage directory doesn't have write permissions on it.

 Solution: 
 By default named group is added on zone storage directory.

 In order to give permissions execute below command:
    chmod 770 /var/named/
Restart named service.

 Incase bind is using "chroot environment" then execute below command:

    chmod 770  /var/named/chroot/var/named/data/

Restart named service.
