I successfully installed and setup the zimbra appliance at Amazon AWS on the small instance through the turnkey hub. Once tested, I tried to update from the base install of V5 to V6 so that I could add the ZeXtras sync client. I downloaded and unpacked the appropriate file. First, it asked me to change the /etc/hosts information to reflect my external ip, FQDN and a hostname. So I did that. This brings me to my first question: It specified FQDN, so I put in mail.mydomain.com with the elastic IP and a new hostname. Was that the right thing to do? I setup the appliance initially with mydomain.com and mail.mydomain.com with an A record. I know that when I ran the file after installing it, it made my email addresss and the domain mydomain.com. Did these changes hurt my server?
Next, I tried to re-do the install. However, it would not let me complete it because it said I need 5gb of storage but only had 1gb. So my second question is: How do I add the needed storage space?
