OpenIndiana has an ancient version of GParted that is simply broken. When I see GParted, I'm very glad because I think I will not have to deal with CLI tools. GParted is a very user friendly partition manager. It turned out I'm wrong. This version of GParted will not even open. I should notice the fact that it even doesn't have its proper icon so it definitely is lacking of maintenance and it's very likely not going to work from the beginning.

Btw, if you can't or don't want to sync with Linux GParted, please remove it so it will not confuse new users. Thank you.
