[SOLVED] Renaming server's host name

[lytledd]

Hey everybody,

Maybe someone can help me here. I'm currently in the process of renaming our work server's hostname. Running the same version as posted in my profile, but the NE edition.

The original server was named exactly as our domain, example.com, but the web portal access was always to wm.example.com.

This is causing issues, so I need to change the hostname to wm.example.com as well.

I've been following the wiki page:

ZmSetServerName - Zimbra :: Wiki

I'm currently running a split DNS, I have the old host and new host in the DNS, pointing to our DMZ ip address, I have both A and MX records:

Doing a

host `hostname`
wm.example.com has address 10.0.0.12

My host file shows:

cat /etc/hosts
127.0.0.1       localhost localhost.localdomain
10.0.0.12       example.com      example
10.0.0.12       wm.example.com   wm

The renaming went without error, I changed my /etc/hostname to the wm.example.com and rebooted.

When trying to start Zimbra, I get the following errors:

zmcontrol start

        zmconfigd               Stopped
                zmconfigd is not running.

And /opt/zimbra/log/mailbox.log shows

2011-05-15 08:37:18,311 FATAL [main] [] system - Could not find an LDAP entry for server 'wm.example.com

It would appear that the zmsetservername command is not getting everything.

Any suggestions would be appreciated,

Doug

Your obfuscation of the DNS records is somewhat confusing (at least for me). You have two A records pointing at different servers, your public IP and your private IP (you should only have the private LAN IP in the Split DNS) and neither of those is named "wm.epiinc.com". You also should have just the one entry for the new servername in the hosts file. From what you've posted I can't tell exactly what your problem is.

Sorry about that Bill, It seems I missed one. I was trying to remove any indication of our real domain. And, only after I started posting did I noticed the public IP address on the 2nd A record, I'll fix that on Monday.

I only had 1 1/2 hours downtime window and had to put things back. I'm planning on getting space on our ESX server, recreating the production machine and trying again from there.

As for the 2nd A record, it's a Alias IP address on eth0

ifconfig

Just an update. I had the time to try again last night. This time, I cleaned up my DNS entries and updated my /etc/hosts with the new name only. At that point, the rename went without a hitch.
