Zimbra fails after hostname change

[linusoft]

Hello,
I've broken a working zimbra server whilst migrating Samba domains.
the server is a Samba PDC, and I have changed the domain name, hosts file and DNS to the new domain.
Unfortunately I did all this before thinking about zimbra, and it only came to my attention once I migrated users also, and then found that email is not working.

I have reverted my hosts file to the previous domain, and run the following:
/opt/zimbra/libexec/zmsetservername -n tux.tasc

I get the result:
ERROR: service.FAILURE (system failure: ZimbraLdapContext) (cause: javax.naming.CommunicationException -n:389)
Host -n

Seemingly an LDAP problem. So far I have found no useful posts that do not required running the installer again. But I don't want to lose any emails from the existing mailboxes.

Any suggestions?

Thanks in advance.

It seems that you have copy-paste the following command :

/opt/zimbra/libexec/zmsetservername -n <servername>

And forgot to replace <servername> with your Zimbra hostname so the paramater sent to Zimbra is -n only without any parameter.

Did you have any backup, especially an LDAP configuration backup?

Thanks vavai,

I tried to restore from backup, but found it to be corrupt. I then tried to restore my DNS settings (actually added the original domain to /etc/hosts and created a new DNS zone with the old domain.
then, I re-ran the zmsethostname command, but omitting the -n switch. This has restore zimbra to full working state.
I will now consider if I want to change the hostname again, or to leave my additional DNS zone in place.

Thanks for your help.
