Для этого на любом работающем узле кластера:

1. Настроить Задать ограничения на запуск ресурса "p_iSCSITarget":
   

   Command
   sudo pcs constraint colocation add "p_iSCSITarget" with Promoted "p_DRBD-clone"

   Command
   sudo pcs constraint order promote "p_DRBD-clone" then start "p_iSCSITarget"

   Блок кода
   Adding p_DRBD-clone p_iSCSITarget (kind: Mandatory) (Options: first-action=promote then-action=start)

2. Настроить Задать ограничения на запуск ресурса "p_iSCSI_lun1":
   

   Command
   sudo pcs constraint colocation add "p_iSCSI_lun1" with "p_iSCSITarget" INFINITY

   Command
   sudo pcs constraint order "p_iSCSITarget" then "p_iSCSI_lun1"

   Блок кода
   Adding p_iSCSITarget p_iSCSI_lun1 (kind: Mandatory) (Options: first-action=start then-action=start)

3. Настроить Задать ограничения на запуск ресурса "ClusterIP": 
   

   Command
   sudo pcs constraint colocation add "ClusterIP" with "p_iSCSI_lun1" INFINITY

   Command
   sudo pcs constraint order "p_iSCSI_lun1" then "ClusterIP"

   Блок кода
   Adding p_iSCSI_lun1 ClusterIP (kind: Mandatory) (Options: first-action=start then-action=start)

4. Проверить созданные ограничения:
   

   Command
   sudo pcs constraint

   Вывод:
