Hello
When I restart a slave resource, master_uname is set correctly at slave node.
------------------ Operation ------------------------------------------------
A and B is started.
node A : Slave
node B : Slave
--> master_uname is empty on monitor. It's OK because there is no master.
B is promoted
node A : Slave
node B : Master
--> master_uname is empty on monitor
A is stopped. (use #crm node standby)
node A : Stopped
node B : Master
--> master_uname of B is empty on monitor
A is started. (use #crm node online)
node A : Slave
node B : Master
--> master_uname of A is set,
but master_uname of B is empty on monitor.
--------------------------------------------------------------------------
I opened a bugzilla.
