Error boot opensolaris 2008.05: panic Page fault occurred in module zfs due to a NULL pointer dereference or how to move boot file system to other zpool
I definitely recommend you to use opensolaris 2009.06, but if you for some reason stay on 2008.05 you can encounter problem same as I had. For me it came after power outage - and I wanted my system recovered as I use it as virtualization platform (14 quests) on VirtualBox hypervisor.
When booted into single-user from LiveCD I saw my booting ZFS pool and root file system is OK and consistent. It was not rpool zpool (the zpool name was bootpool) because I did "booting zpool migration" once in the past. So it came in my mind to try fix my system boot problem this way - creating new zpool and migrate booting file system into it. I'd tried to find proper steps in summer 2008, but even did boot filesystem migration successfully - I didn't documented the steps ;o(
The original thread is here: http://www.opensolaris.org/jive/thread.jspa?messageID=248211𼦓
Now my system was panicing in a loop on page fault occurred in module zfs due to a NULL pointer dereference, no matter I removed snapshots, clones, other boot environments (beadm (1M)). I'm not exactly sure of root cause - this happened just after system lost it power. I've never saw this system panic before this one for any reason.
The console output is here:

When you want just migrate your booting zpool into another zpool the process is the same as there is nothing specific to my problem - you can consider my system to be operational again as side effect here.
so here you can read the steps which lead back to working system after new booting zpool was created:

2. =>IMPORT ORIGINAL BOOT ZPOOL WITH -f
May 26 09:39:16 su: 'su root' succeeded for root on /dev/console zpool imSun Microsystems Inc. SunOS 5.11 snv_86 January 2008 port bo-bash-3.2# zpool import bootpool cannot import 'bootpool': pool may be in use from other system use '-f' to import anyway -bash-3.2# zpool import -f bootpool
3. =>CREATE OR IMPORT OTHER ZPOOL (SAME PHYS HDD TYPE SHOULD BE PREFERRED) WHICH RESIDES ON SOLARIS2 FDISK PARTITION AND HAS SLICE DEFINED
-bash-3.2# zpool import bootpool2 cannot import 'bootpool2': pool may be in use from other system use '-f' to import anyway -bash-3.2# zpool import -f bootpool2 -bash-3.2# -bash-3.2# zpool list NAME SIZE USED AVAIL CAP HEALTH ALTROOT bootpool 928G 90.1G 838G 9% ONLINE - bootpool2 928G 2.39M 928G 0% ONLINE -
This could be second disk in ZFS mirror, this mean you have to detach this disk from zpool first and force -f the zpool creation.
4. =>CREATE ZFS SNAPSHOTS FOR YOUR ORIGINAL FSs HERE NAMED AS @2
-bash-3.2# zfs list NAME USED AVAIL REFER MOUNTPOINT bootpool 90.1G 823G 56.5K /bootpool bootpool@2 19K - 56.5K - bootpool/ROOT 90.1G 823G 18K /bootpool/ROOT bootpool/ROOT@2 15K - 18K - bootpool/ROOT/opensolaris 90.1G 823G 65.2G legacy bootpool/ROOT/opensolaris@Mar032009befVirtBOXupgradeTo214 24.8G - 66.8G - bootpool/ROOT/opensolaris@send2backup 68K - 65.2G - bootpool/ROOT/opensolaris@2 0 - 65.2G - bootpool2 2.29M 913G 56.5K /bootpool2 bootpool2@2 0 - 56.5K - bootpool2/ROOT 18K 913G 18K /bootpool2/ROOT bootpool2/ROOT@2 0 - 18K - -bash-3.2# <l/ROOT/opensolaris@2 | zfs receive bootpool2/ROOT/opensolaris
5. =>SEND THE SNAPHOST's DATA INTO NEW ZPOOL CREATED EARLIER
zfs send bootpool@2 | zfs receive -F bootpool2 zfs send bootpool/ROOT@2 | zfs receive bootpool2/ROOT zfs send bootpool/ROOT/opensolaris@2 | zfs receive bootpool2/ROOT/opensolaris
This will sent all file systems' data into new zpool created in step 3.
6. =>SET NEW ROOT FS MOUNT POINT AS LEGACY
-bash-3.2# zfs get mountpoint bootpool/ROOT/opensolaris NAME PROPERTY VALUE SOURCE bootpool/ROOT/opensolaris mountpoint legacy local -bash-3.2# zfs get mountpoint bootpool2/ROOT/opensolaris NAME PROPERTY VALUE SOURCE bootpool2/ROOT/opensolaris mountpoint /bootpool2/ROOT/opensolaris default -bash-3.2# -bash-3.2# zfs set mountpoint=legacy bootpool2/ROOT/opensolaris -bash-3.2# zfs get mountpoint bootpool2/ROOT/opensolaris NAME PROPERTY VALUE SOURCE bootpool2/ROOT/opensolaris mountpoint legacy local -bash-3.2#
This need to be done for proper boot process and to be referenced in /etc/vfstab see step 8.
7. =>MOUNT THE NEW ROOT
mount -F zfs bootpool2/ROOT/opensolaris /mnt
8. =>EDIT MENU.LST AND VFSTAB IN NEW ZPOOL TO REFLECT ZPOOL NAME CHANGE
-bash-3.2# cat /bootpool2/boot/grub/menu.lst serial --unit=0 --speed=9600 --word=8 --parity=no --stop=1 terminal serial ##splashimage /boot/grub/splash.xpm.gz timeout 30 default 0 #---------- ADDED BY BOOTADM - DO NOT EDIT ---------- title OpenSolaris 2008.05 snv_86_rc3 X86 IEDIed bootfs bootpool2/ROOT/opensolaris kernel$ /platform/i86pc/kernel/$ISADIR/unix -B $ZFS-BOOTFS,console=ttya module$ /platform/i86pc/$ISADIR/boot_archive #---------------------END BOOTADM-------------------- # Unknown partition of type 238 found on /dev/rdsk/c10t1d0p0 partition: 1 # It maps to the GRUB device: (hd0,0) . # Unknown partition of type 238 found on /dev/rdsk/c10t4d0p0 partition: 1 # It maps to the GRUB device: (hd1,0) . title bootCLONE bootfs bootpool/ROOT/bootCLONE kernel$ /platform/i86pc/kernel/$ISADIR/unix -B $ZFS-BOOTFS module$ /platform/i86pc/$ISADIR/boot_archive #============ End of LIBBE entry ============= -bash-3.2# -bash-3.2# cat /mnt/etc/vfstab #device device mount FS fsck mount mount #to mount to fsck point type pass at boot options # /devices - /devices devfs - no - /proc - /proc proc - no - ctfs - /system/contract ctfs - no - objfs - /system/object objfs - no - sharefs - /etc/dfs/sharetab sharefs - no - fd - /dev/fd fd - no - swap - /tmp tmpfs - yes - bootpool2/ROOT/opensolaris - / zfs - no - /dev/dsk/c10t0d0s1 - - swap - no - /dev/dsk/c10t4d0s1 - - swap - no - -bash-3.2#

Now you can try to boot from new zpool - in GRUB you can type "e" - edit to see if your booting zpool change is in place (the menu.lst file). Be careful the directive "bootfs" is specific to same releases of opensolaris, new versions use "findroot" directive.
Zpool cache file replacement caused all other zpools not to be imported this time - you need to do it manualy just once in the next step to make it automatic during boot.
