Hi everyone. I'm about to set up our ZCS 5 installation on a RHEL5.1 Cluster between 2 nodes. The active/standby setup will be using Red Hat Cluster Suite 5.1 and use a Dell MD3000 shared storage array.
The Zimbra documentation for setting up a RedHat cluster mentions installing the LDAP and MTA components on separate servers than the Mailstore nodes. I just want a sanity check to make sure it isn't a problem to install the LDAP+MTA components on my two clustered nodes along with the mailstore and everything else? Since only 1 will be active at a time, I don't see how this would be a problem but I thought I'd make sure first.
Also, we are going to be using a fencing mechanism (Dell PERC controllers) that is supported by the latest RHCS but isn't an option in the Zimbra installer script for setting up cluster nodes. Should I just select an APC fencing config during the install and then use the RHCS management tools to later go back in and change the fencing config?
