Symptoms

What should I check if a DNS record is not updated in one of the DNS's:

Resolution

A list of things to check in the Name server (Domain Director):

 

1. check Mount from primary to secondary DNS.

 

[root@nameserver root]# df -h

Filesystem            Size  Used Avail Use% Mounted on

 

exodus:/usr/sphera/DomainDirector/etc

                       35G   25G  8.6G  74% /mnt/slave

 

2. Check domain exists in named.conf

[root@nameserver root]# cd /usr/sphera/DomainDirector/etc/

 

less named.conf

 

/ serach for requested dns record

 

3. Check domain DB file exists in name server:

 

cd /usr/sphera/DomainDirector/var/named/

 

ls -l | grep domainname.com

 

4. Enable and disable DNS for this domain

 

See that named record or DB file were created.

 

5. Check named process is running:

 

ps -efw |grep named to restart it you can use  /etc/rc.d/initd/Snamed_dm stop/start

 

6. Execute sphadmin

 

stop and start DomainDirector

 

7. Restart bind (named process) in master (ServerDirector)

 

/etc/rc.d/initd/Snamed_hd in the ServerDirector machine. Check that notifies are being sent using the /var/log/messages log after the named process was restarted.
