Upgrading to Power DNS fails

[WebHostPro]

Hi,

I've tried to upgrade to power dns on a server multiple times now and it keeps failing. Here is the errors, but I can't tell of something that I can change to fix them.


Service Error

(XID 7uzu5z) The “pdns” service failed to start.

pdns has failed. Contact your system administrator if the service does not automagically recover.

Nameserver conversion complete

Those warnings aren't indicative of what cause pdns to fail - pdns doesn't recognize BIND's "hint" zones. You can read about what these are here: IANA — Root Files

It looks like the conversion does complete though per the end message. When you start/restart pdns what is the output?

/scripts/restartsrv_pdns

 

[WebHostPro]

I get this messge:

[[email protected] ~]# /scripts/restartsrv_pdns
warn [restartsrv_pdns] The system is unable to find systemd configuration for the 'pdns' service...
(XID 2jny52) The “pdns” service is not configured.

But I changed back to bind when the conversion failed. I need to work. Are you saying I should convert then try the restart to check for errors?

 

[cPanelLauren]

Yes, pdns wouldn't start in the instance you switched back to bind. I mean when you run the conversion and if it fails, what is the output when you attempt to restart the service. I'd like to see the error. Also, if you run the following does the service start:

/scripts/rebuilddnsconfig

This will rebuild the configuration and restart the nameserver

Sorry for the delay

This is a funny typo: automagically. I wish it would automagically fix itself.

Hello,

I'm curious, it notes it's parsing 14,725 zones and I wonder if part of the issue is a timeout (or the script not having a long enough timeout for a response) or if something else is listening on 53 when you're attempting the switch.

• That being said, when you do switch (right after) what is the output of the following:

  netstat -plan |grep :53 |awk '{print $7}'

• Then when you rebuild the dns config what is the output of the following:

  journalctl -f -u pdns

  • (alternatively you could run journalctl -xe )
• As well as the output of these:

  systemctl status pdns

  systemctl status named

P.S. Automagically isn't a typo, it's definitely on purpose
