Hello Digimer Thank you for your advice. * GNBD I've already succeed to mount GNBD. locking_type = 1 Should I change lock_type = 3 ?, If not, what problem will be occur?? * fence_apc some of reason, I can't get use APC switch. (That configuration example is test environment. ) so I asked alternative solution. * fence_wol I can't find fence_wake_on_lan. so I'm thinking to create it. WOL supports Power on and Power off ( I'll test later ). So, It's will be fence tool. And I downloaded fence_na, It was written in Perl script. so I want to change fence_na to use wol command. Could you point me to good reference to build fence_wol. (Of course!!. fence_na is good reference) Thank you for your advice again.
