New issue 1023 by [email protected]: Master master-capable option bug
https://code.google.com/p/ganeti/issues/detail?id=1023
st0-01/02/03 are hardware nodes, st0-mc1/2 are two master-candidates vms
(with vm-capable = off). I was messing around with master-capable,
master-candidate and candidate-pool-size and removed the master capable
flag from current master. As far as i can tell st0-mc1 is still the master
but there is a bug on the code.
st0-mc1:~# gnt-node modify --master-capable no st0-mc1

status shows I'm the master node, will not demote
Tue Dec 2 18:51:01 2014 Configuration data is not consistent: Master node
is not a master candidate
