Hi, Andreas, Lars, and everybody
I will try newer version.
But, I want below.
Primary
demote
wait 5-10 seconds
check Secondary is promoted or
still secondary or disconnected
if Secondary is promoted and still primary,
set local "outdate"
(This means shutdown only Primary)
if Secondary is still secondary or disconnected,
not set local "outdate"
(This means shutdown both of Primary and Secondary)
disconnect
shutdown
Seconday
check Primary
if Primary is primary, set local "outdate"
if Primary is demoted(secondary), not set "outdate"
disconnect
shutdown
