ZCS 8.8

 - This article is a Work in Progress, and may be unfinished or missing sections.

Scenario I - Single Server

You have been running ZCS-88 using the Next Generation Suite, and you have a dedicated disk for /opt/zimbra/, something like...

/dev/mapper/vg_zcs-lv_root
xxG  xxxG   xxG  xx% /
tmpfs                /dev/shm
/dev/sda1            /boot
/dev/sda2            /opt/zimbra/

But something has happened to the server node, effecting the operating system, which will require a reinstall of the operating system, and ZCS-88.

Reinstall the Operating System

When you reinstall the operating system, make sure the disk containing /opt/zimbra/ is not mounted yet.

Reinstall ZCS-88 with Next Generation Modules

When you are ready to reinstall ZCS-88, make sure the /opt/zimbra/ is now mounted.

Now, run the installer as the root user.

./install.sh

*OR*

./install.sh -l /path/to/the/license/ZCSLicense.xml

During the ZCS-88 Reinstall

You may see the following

The Zimbra Collaboration Server does not appear to be installed,
yet there appears to be a ZCS directory structure in /opt/zimbra.

Would you like to delete /opt/zimbra before installing? [N]

**Make sure to select N so /opt/zimbra/ is NOT removed**

During the reinstall, you will see this dialog prompt; but your Domain will be different.

DNS ERROR resolving MX for test3.zextras.local
It is suggested that the domain name have an MX record configured in DNS
Change domain name? [Yes] 

**Go ahead and select Yes, and enter your domain**

You may, or may not see this following diaglog prompt

It is suggested that the MX record resolve to this host
Re-Enter domain name? [Yes]

**Go ahead and enter No, and continue**

Now you should be at the Main Menu, and will likely see the following; again your domain will be different

   6) zimbra-store:                            Enabled                       
        +Create Admin User:                    yes                           
        +Admin user to create:                 admin@zextras.local           
******* +Admin Password                        UNSET   

Select 6 and hit Enter

Address unconfigured (**) items  (? - help) 6

Now you should see Store configuration be displayed

Store configuration

   1) Status:                                  Enabled                       
   2) Create Admin User:                       yes                           
   3) Admin user to create:                    admin@zextras.local           
** 4) Admin Password                           UNSET                         

Now you should see this at the bottom

Make sure to select 2 to change this
