Lucreate error on Solaris 10 10/09 root ZFS

Question

Hi guys,
I got some errors while trying out live upgrade on Solaris 10 10/09 root ZFS x86 environment.
I do intent to do this in the SPARC environment but not comfortable with the experience so far.
First of all, I have a separate zpool dataset - "rpool/opt".
Not sure if this is causing the error below.
Anyone can help to advice? TIA

I had the exact same problem.
I found that by simply renaming rpool/opt to rpool/ROOT/s10x_u6wos_07b/opt seemed to fix this problem:
$ umount -f /opt
$ zfs rename rpool/opt rpool/ROOT/s10x_u6wos_07b/opt
$ zfs set canmount=noauto rpool/ROOT/s10x_u6wos_07b/opt
$ zfs mount rpool/ROOT/s10x_u6wos_07b/opt
$ lucreate -n test
