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.

If it's possible, rename your production /opt/zimbra/ directory.

mv /opt/zimbra/    mv /opt/zimbraSAVE/


Now, run the installer as the root user using the software option.

./install.sh -s

*OR*

./install.sh --software

During the ZCS-88 Software Reinstall

Observe at the end of the software install, you will see the following

Running Post Installation Configuration:

Software Installation complete!

Operations logged to /tmp/install.log.SviTipi8

Now observe, you have two zimbra directories

drwxr-xr-x  30 root root 4096 Aug 24 14:29 zimbra
drwxr-xr-x  30 root root 4096 Aug 17 13:20 zimbraSAVE

Since the software install had created the /opt/zimbra/ directory, lets move it out of the way

mv /opt/zimbra/   /opt/zimbraSOFTWARE_INSTALL/

Now, lets put our production directory back into place

mv /opt/zimbraSAVE/   /opt/zimbra/
