hi,

I moves to opensuse's pacemaker-1.1.2. Same result:

# ptest -sL
(...)
resDRBD:1 promotion score on hakurs07: 10000
resDRBD:0 promotion score on hakurs08: 10000
resDRBD:1 promotion score on hakurs07: INFINITY
resDRBD:0 promotion score on hakurs08: -INFINITY

shouldn't it be

resDRBD:1 ... hakurs07
resDRBD:0 ... hakurs07
resDRBD:1 ... hakurs08
resDRBD:0 ... hakurs08

?
