Pacemaker2系でノードをstandbyに落とすやり方

Last updated at Posted at 2024-01-30

Pacemaker2系を使っててノードをStandbyに落とす時のコマンドメモ。
crm node standby でもなく、 pcs cluster standby でもなかった我が家のHAクラスタ環境。

コマンドを探すのに苦労したのでメモしておく。

HAクラスタからノードを外す

  • 例: rpi2b-ds-3 をStandbyにする
    crm_standby -N rpi2b-ds-3 -v on
    

HAクラスタにノードを戻す

  • 例: rpi2b-ds-3 をOnLineにする
    crm_standby -N rpi2b-ds-3 -v off
    

standby属性をon/offすることで、クラスタから切り離す感じ。
