Hi again,
U said when in want to shutdown or restart clusters , always use "cshutdown"
I tried cshutdown -r on head node , but it says u must specify a time , so i
used cshutdown -r -t 10 , same message showed up, also chutdown -r -t 10
--all , was tested, and also cshutdown -r -t 0 , all of them have same
problem , what's the matter?!!
cheers.
