[SOLVED] Disaster recovery

[jayel]

Hello,

I want to transfer my zimbra to a new server !
Now I am running on a ubuntu 6.06.
I have a ubuntu 8.04 running that I want to setup my zimbra.

I followed the steps from your wiki : Network Edition Disaster Recovery
I am on the 6th step of recovery.

I copied the last full and incr that follows to my new server /opt/zimbra/backup/sessions.

Now I have to do a zmrestorrldap -lb

When this is done I get an error :

Starting ldap...ldap_url and ldap_master_url cannot be the same on an ldap replica
ERROR: failed to start ldap.

What is wrong ?

Which wiki article and what is your Zimbra configuration (multi-server, single server etc.)?

[jayel]

Hallo,

This is the wiki article and it is a single server.

Greets,

John

The correct command should be as follows (do you still get the error with this?):

zmrestorrldap -lbs

Have you also made sure that the /etc/hosts file is the same (the same FQDN as the old server) and the DNS A & MX records resolve to the new server?

[jayel]

Yes, this was a typo on the forum, sorry.

I have setup a splitDNS and did a nslookup and everything looks fine:

root@mail:~# nslookup robotronic.be
Server:         192.168.0.236
Address:        192.168.0.236#53

Name:   robotronic.be
Address: 192.168.0.236

root@mail:~#

greets,
John

Just for confirmation let's see the full output of the following commands (run on the new server):

cat /etc/hosts
cat /etc/resolv.conf
dig yourdomain.com any
dig yourdomain.com mx
host `hostname`  <- use that exact command with backticks not single quotes

You seem to have no A or MX resolution for this domain (robotronic.be), I assume you've also disabled the firewall and AppArmor on the server?

[jayel]

I have done the restore, and it was a password error of my root_ldap_password.

But now I can't send mails?

Here the a cut of the zimbra.log

May 16 16:31:33 mail postfix/smtp[15947]: connect to mx1.hotmail.com[65.55.92.184]: Connection refused (port 25)
May 16 16:31:33 mail postfix/smtp[15947]: connect to mx2.hotmail.com[65.54.188.126]: Connection refused (port 25)
May 16 16:31:33 mail postfix/smtp[15947]: connect to mx2.hotmail.com[65.55.37.88]: Connection refused (port 25)
May 16 16:31:33 mail postfix/smtp[15947]: connect to mx1.hotmail.com[65.55.92.136]: Connection refused (port 25)
May 16 16:31:33 mail postfix/smtp[15947]: connect to mx4.hotmail.com[65.55.92.136]: Connection refused (port 25)

Is this an apparmor problem or is ubuntu 8.04 blocking port 25?
If so How can I check this ?

If you have apparmor or the firewall enabled it could be causing you problems, it's not recommended to run either on the Zimbra server. The error you've posted is indicative of a problem at the receiving server, howevere I can connect to those servers without problems. You can check the connection with telnet by FQDN or IP like this:

telnet 65.55.92.184 25
telnet mx1.hotmail.com 25
