[Pacemaker] S_POLICY_ENGINE state continues being maintained

[Kazunori INOUE]

Hi,

I'm using pacemaker-1.1 (c3486a4a8d. the latest devel).
After fencing caused by split-brain failed 11 times, S_POLICY_ENGINE state is kept even if I recover split-brain.

1. disconnect network connection

2. wait until fencing failed 11 times
 [dev1 ~]$ egrep "CRIT|too_many_st_failures" /var/log/ha-log

 [dev2 ~]$ egrep "CRIT|too_many_st_failures" /var/log/ha-log

3. recover network disconnection

S_POLICY_ENGINE state continues being maintained although a member's join seems to have succeeded.

 [13:47:54 root at dev1 ~]$ crmadmin -S dev2
 Status of crmd at dev2: S_POLICY_ENGINE (ok)
