obsługa głównego systemu plików jako ZFS.
Co ciekawe oprócz instalatora (próbowałem tylko tekstowego) obsługę /
jako ZFS mają również narzędzia od Live Upgrade.
Dodatkowo można zmigrować obecny system zainstalowany na UFS
na dodatkową pulę ZFS.
Wszystko ładnie i pięknie, ale jest niestety BUG (6707013), który utrudnia życie...
Na potrzeby testów usunąłem jedno środowisko uruchomieniowe,
w jego miejsce zrobiłem nową pulę ZFS:
# zpool create rpool c0d0s4
invalid vdev specification
use '-f' to override the following errors:
/dev/dsk/c0d0s4 contains a ufs filesystem.
# zpool create -f rpool c0d0s4
# zpool list
NAME SIZE USED AVAIL CAP HEALTH ALTROOT
data 23,2G 4,78G 18,5G 20% ONLINE -
rpool 11,7G 95,5K 11,7G 0% ONLINE -
Tworzymy nowe środowisko uruchomieniowe na nowej puli ZFS:
# lucreate -n be_zfs_b90 -p rpool
Checking GRUB menu...
This system contains only a single GRUB menu for all boot environments. To
enhance reliability and improve the user experience, live upgrade requires
you to run a one time conversion script to migrate the system to multiple
redundant GRUB menus. This is a one time procedure and you will not be
required to run this script on subsequent invocations of Live Upgrade
commands. To run this script invoke:
/usr/lib/lu/lux86menu_propagate /path/to/new/Solaris/install/image
where /path/to/new/Solaris/install/image is an absolute
path to the Solaris media or netinstall image from which you installed the
Live Upgrade packages.
System musi zaktualizować /boot/grub/menu.lst ...
W tym celu montujemy płytkę z SXCE90:
# lofiadm -a /mnt/new/sxce90.iso
/dev/lofi/1
# mount -F hsfs -o ro /dev/lofi/1 /mnt/x/
Nie wiem dlaczego, ale musiałem usunąć inne BE, aby Live Upgrade zadziałało...

No i zaczyna się :) Nie mam zarówno czasu, ani chęci szukać co poszło nie tak,
jednak szybko patrząc w core widzę, że jakiś system plików był już zamontowany.

**********************************************************************
The target boot environment has been activated. It will be used when you
reboot. NOTE: You MUST NOT USE the reboot, halt, or uadmin commands. You
MUST USE either the init or the shutdown command when you reboot. If you
do not use either init or shutdown, the system will not boot using the
target BE.
**********************************************************************
In case of a failure while booting to the target BE, the following process
needs to be followed to fallback to the currently working boot environment:
1. Boot from Solaris failsafe or boot in single user mode from the Solaris
Install CD or Network.
2. Mount the Parent boot environment root slice to some directory (like
/mnt). You can use the following command to mount:
mount -Fufs /dev/dsk/c0d0s0 /mnt
3. Run
environment root slice, as shown below:
/mnt/sbin/luactivate
4. luactivate, activates the previous working boot environment and
indicates the result.
5. Exit Single User mode and reboot the machine.
