Migration to RHEL 5.3 and ZCS 5.0.16GA

[cosmicwombat]

While I have posted a ticket, I though I might post the question here too.

I asked the Zimbra support for advise on moving from an old box to a new one and they gave me this wiki post to follow.

Network Edition: Moving from 32-bit to 64-bit Server - Zimbra :: Wiki

Something went amiss and Zimbra won't start. I know why, just not the how.

The old hardware was running RHEL 4.5 and Zimbra 5.0.13. The new hardware is RHEL 5.3. I first upgraded the old box to 5.0.16 and then went through the procedure using 5.0.16 on the new box. It went well until the last step. zmcontrol start showed everything starting, but a backup would not run. I started and stopped Zimbra watching the log.

The log showed something at 0.0.0.0:25 preventing postfix from running. I made sure that neither postfix or sendmail was installed before starting the 5.0.16 install on the new box.

The only possibility is something called fetchmail, which seems to be a dependency of sendmail (which I uninstalled from the default RHEL install.) On next go around, I'll check it.

Where else should I look for port 25 conflicts? Other thoughts?

On my CentOS 5.3 i386 box I left sendmail installed and used chkconfig to set it not to start. You might check /opt/zimbra/log/startup.log

netstat -anp | grep ":25"

will show you which process is holding onto port 25.

rpm -qa | grep sendmail

will double check to make sure sendmail is installed or not. yum -e sendmail will remove it if it is in fact installed. I have sendmail installed and running over a different port as I couldn't figure out how to get the Dell raidmon app to use postfix and not sendmail for delivery.

I found fetchmail and removed it. I have scheduled another attempt for Tuesday...
