1つの注意点は、pcs cluster stop server_b.test.local構成を実行すると、グループ内のすべてのリソースが別のノードに移動されることです。
どうなりますか？私が言ったように、それはうまくいき、それ以来何の変化もありませんでした。
よろしくお願いします！

少し混乱しています。/これは予想される動作ですか？
答え1
私の最後の答えが正しいかどうかはわかりませんが、詳しく調べてから次のことをman pcs見つけました。
move [ターゲットノード] [--master] [lifetime=] [--wait[=n]] ノードを無効にする -INFINITY 位置制約を生成し、現在実行中のノードからリソースを移動します。宛先ノードが指定されている場合は、宛先ノードを優先的に選択するために INFINITY 位置制約を作成し、そのノードにリソースを移動します。 --masterを使用する場合、コマンドの範囲はマスターロールに制限され、マスターID（リソースIDではない）を使用する必要があります。寿命が指定されると、制約はその時間後に期限切れになります。それ以外の場合、デフォルトは無限に設定され、「pcsリソースのクリーンアップ」または「pcs制約の削除」を使用して制約を手動で消去できます。 --waitが指定されている場合、PCはリソースが移動するまで最大n秒を待ち、成功した場合は0を返し、エラーは1を返します。 'n'を指定しない場合、デフォルトは60分です。特定のノードで実行されないようにするのが最善ですが、そのノードにフェールオーバーできるリソースが必要な場合は、「pcs locationvoids」を使用してください。
を使用すると、制限 pcs resource clearが解除され、リソースを移動できます。
答え2
グループ化されたすべてのリソースのデフォルト設定の制限が問題であるscore:INFINITY可能性があります。 PacemakerのINFINITY場合とほぼ同じで、1,000,000スコアに割り当てることができる最も高い値です。
使用時には以下が適用されますINFINITY（ClusterLabsのマニュアルを参照）。
6.1.1. Infinity Math Pacemaker implements INFINITY (or equivalently, +INFINITY) internally as a score of 1,000,000. Addition and subtraction with it follow these three basic rules: Any value + INFINITY = INFINITY Any value - INFINITY = -INFINITY INFINITY - INFINITY = -INFINITY
1,000好みのスコアを、または10,000などに変更してINFINITYからテストをやり直してください。
