Fork原田と申します。
Pacemakerの監視として、
Stonithも追加しているのですが、
下記の動きが正しいのか分からなくなってしまいました。
ご教示をお願いいたします。
構成
A プライマリ
B セカンダリ
の2台構成
DRBD8+Pacemaker1.1.17 +corosync2.4
パターン1
① Aをシャットダウン
② Bにフェイルオーバー
③ Aを電源ONにすると、Bが再起動される。(Stonith操作？)
そして、Aにフェイルバックされる
④そして、DRBD が
StandAlone Primary/Unknown となってしまう。
パターン2
① Bをシャットダウン
② Aへフェイルオーバー
③ Bを電源ON Aが再起動される(Aはプライマリのまま)
CRM設定は下記となります。
