Hello the list,
I thought that it should be easy to do a clone (not in the term of zfs) of a
disk with zpool. This manipulation is strongly inspired by
http://www.opensolaris.org/jive/thread.jspa?messageID=135038
and
http://www.opensolaris.org/os/community/zfs/boot/
But unfortunately this doesn''t work, and we do have no clue what could
be wrong
on c1d0 you have a zfs root
create a mirror of this disk:
zpool attache rootpool c1d0 c2d0
wait that it construct c2d0
zpool offline
#install the grub
/usr/sbin/installgrub /boot/grub/stage1 /boot/grub/stage2 c2d0
shut down
remove the disk c1d0 and place the disk on c2d0 in c1d0
boot in failsafe
clean the zpool
zpool import rootpool
zpool rootpool c1d0 #(yeah I know this look strange because
at that time we have a zpool status saying that the zpool is constitued of two
disk c1d0 and c1d0)
# try to repair the zpool.cache
mkdir /tmp/w_zfs # w stand for write
mount -F lofs /tmp/w_zfs /etc/zfs
touch /etc/zfs/foo # to check if writable
rm /etc/zfs/foo
zpool export rootpool
zpool import rootpool
## okay we can see now that there is a /etc/zfs/zpool.cache
# lets put the new zpool.cache in the rootpool/rootfs
mkdir /tmp/rootpool
mount -F zfs rootpool/rootfs /tmp/rootpool
cp /etc/zfs/zpool.cache /tmp/rootpool/etc/zfs/
# update the bootadm
/usr/sbin/bootadm update-archive -v -R /tmp/rootpool
