Hi,
I a Solaris 10 Update 10 box with 1 disk which is used for two different
zpool:

Note, as you can see, the slice 0 i used for 'rpool' and the slice 7 is
used for 'opt'. The autoexpand propierty is enabled in 'rpool' but is
disabled in 'opt'
This machine is a virtual one (VMware), so I can enlarge the disk easily
if I need. Let's say I enlarge the disk 10 GB:
# Before enlarge the disk
root@sct-jordi-02:~# echo | format ; df -h

The size of rpool zpool stills the same.
How to do it?
PS. I know perfectly how to expand any zpool just adding a new device;
actually I think is even better, but that's not the point.

I will face my fear. I will permit it to pass over me and through me.
And when it has gone past I will turn the inner eye to see its path.
Where the fear has gone there will be nothing. Only I will remain.
