Performing Live Upgrade with ZFS

This article basically provides the steps necessary to perform a live upgrade of OpenSolaris with ZFS as the root file system.

I've been working with Solaris and OpenSolaris for quiet sometime, and eventually I've decided to do a fresh install rather than the usual upgrade.

In doing so, I was surprised that my root file system is now under ZFS control rather than the other UFS as per my previous installs/upgrades ... Yipee - looks likes Solaris is coming of age...

1. download the ISO image

   # wget http://dlc.openindiana.org/isos/opensolaris/osol-dev-134-ai-x86.iso

2. mount ISO image as loopback device on /mnt

   # lofiadm -a {ISO_IMAGE}
   # mount -F hsfs /dev/lofi/1 /mnt

3. remove current LU pkgs and reinstall latest

   # pkgrm SUNWluu SUNWluzone SUNWlur SUNWlucfg
   # cd /mnt/Solaris_11/Product
   # pkgadd -d . SUNWluu SUNWluzone SUNWlur SUNWlucfg

4. clone current BE to AE

   # lucreate -c OLD_BUILD -n NEW_BUILD

5. check status

   # lustatus

6. perform upgrade

   # luupgrade -u -n NEW_BUILD -s /mnt

7. recheck status

   # lustatus

8. activate new build image

   # luactivate NEW_BUILD

9. perform reboot to boot new image

   # init 6

   (dont use reboot/shutdown, you must perform an init 6)
