I am sorry to send previous email because of my carelessness.
I just found I still use the old GUI tool coming with 0.9.0. For my
previous evms engine install, I used rpm so all executable commands
shows up in /use/sbin. When I install 0.9.1, I use source code and
make install directly. I thought it would be installed in the same
directory and overwrite the old one but the new command set was installed
in /usr/local/sbin.

After I cleaned up the old command set, GUI works and device nodes
can show up after I commit the change.

Thanks,
