Forkお世話になります。
濱口と申します。
pacemaker + cmanで5対1の冗長化をしようとしているのですが
うまくいっておらず、質問させていただきました。
【問題】
フェイルオーバ時に同一のリソースが2つのノードで動作してしまう
【環境】
OS: CentOS 6.8
pacemaker：1.1.14-8.el6_8.1
cman：3.0.12.1-78.el6
【構成】
ノード：pm1.local - pm6.local
リソースグループ：groupA - groupE
※リソースグループと当該リソースを活性化するノードの対応は以下の通り。
groupA, pm1.local
groupB, pm2.local
groupC, pm3.local
groupD, pm4.local
groupE, pm5.local
pm6.local (groupA - groupEのフェイルオーバ先)
【問題発生の手順】
1. pm1.localから順にpm6.localまでのノードをクラスターに参加させる
2. pm1.localのリソースを故障させる(例：service asterisk stop)
3. pm2.localのリソースを故障させる(例：service asterisk stop)
上記手順の1でそれぞれのノードで意図した通りのリソースが起動します。
手順の2でgroupAがpm1.localからpm6.localへフェイルオーバします。
手順の3でgroupBがpm2.localからpm6.locaへフェイルオーバします。
【期待する動作】
手順の3でgroupBがpm6.localへフェイルオーバせず（すでにgroupAが動作しているため）、故障した状態でpm2.localに残る
