Disabling DNS service for domain in Plesk does not trigger slave DNS zone update

Symptoms

1. Slave DNS servers are configured in Plesk (via Slave DNS extension or any custom integration).
2. Disabling DNS service for a domain in Domains > example.com > DNS Settings > Disable does not trigger slave DNS zone deletion. As a result, the following errors appear in /var/log/messages or /var/log/syslog on the slave server:

   named[2287]: transfer of 'example.com/IN' from 203.0.113.2#53: failed while receiving responses: REFUSED

Cause

Plesk bug #PPPM-7931 which will be fixed in future updates.

Resolution

As a workaround, delete the zones on slave servers manually.

For Linux:

1. Log in to slave DNS server via SSH.
2. Identify zone files location of the file system:

   # find /var/named -name example.com
   /var/named/chroot/var/example.com

   where ‘example.com’ is sample domain name which zone file is to be deleted.

3. Remove the zone files one by one:

   # rm -f /var/named/chroot/var/example.com
