zfs discuss - Aug 2009 - clone rpool to smaller disk

Hi,

I have sol10u7 OS with 73GB HD in c1t0d0.
I want to clone it to 36GB HD

These steps below is what come in my mind
STEPS TAKEN
# zpool create -f altrpool c1t1d0s0
# zpool set listsnapshots=on rpool
# SNAPNAME=`date +%Y%m%d`
# zfs snapshot -r rpool/ROOT@$SNAPNAME
# zfs list -t snapshot
# zfs send -R rpool@$SNAPNAME | zfs recv -vFd altrpool
# installboot -F zfs /usr/platform/`uname -i`/lib/fs/zfs/bootblk
/dev/rdsk/c1t1d0s0
for x86 do
# installgrub /boot/grub/stage1 /boot/grub/stage2 /dev/rdsk/c1t1d0s0
# zpool export altrpool
# init 5
remove source disk (c1t0d0s0) and move target disk (c1t1d0s0) to slot0
-insert solaris10 dvd
ok boot cdrom -s
# zpool import altrpool rpool
# init 0
ok boot disk1

ERROR:
Rebooting with command: boot disk1
Boot device: /pci at 1c,600000/scsi at 2/disk at 1,0  File and args:
no pool_props
Evaluating:
The file just loaded does not appear to be executable.
ok

QUESTIONS:
1. what''s wrong what my steps
2. any better idea

thanks

Hi Nawir,

I haven''t tested these steps myself, but the error message
means that you need to set this property:

# zpool set bootfs=rpool/ROOT/BE-name rpool

cindy,

You are brilliant.
I can successfully boot os after follow the steps below.
But I got some small problem
1. when I "zpool list", I saw two pools (altrpool & rpool)
I want to delete altrpool using "zpool destroy altrpool" but after I
reboot it panic

2. I got this error message
ERROR MSG:
/usr/sbin/pmconfig: "/etc/power.conf" line 16, ufs statefile with zfs
root is no
t supported
