Increase root filesystem on solaris zone using zpool

UNIX Solaris
1

I have a solaris zone of 12 GB and i have to increase the / filesystem to 31GB as requested. Earlier I had expanded filesystems other than / by setting quota to new value like "zfs set quota=new value mountpoint" but I am not sure whether its a good practice in zfs because by default in my environment, the quota and reservation are set to NONE. So I am able to increase the space but I am not sure whether I am doing it the right way or not. Now when it comes to increasing / filesystem, I dont want to take chances and do something stupid. Let me know your views on how to increase the root filesytem of solaris zone using zpool.

FYI : When we see space from global zone using zpool, everything is just a filesystem with some space irrespective of whether its root or other filesystem but still some ideal and right way or views are welcome.

Can you copy and paste this:

prtvtoc /dev/rdsk/<disk where the zfs is located>

You can not add a new disk to an RPOOL unless it is for mirroring, but you might be able to change your partitions and relocate some data on other disks to achieve more space. Even though 12 Gigs should be more than enough for a solaris installation.

Would you use "code" tags for the output, thanks!
