## How to disable preemption
{{< note >}} **Note**: In Kubernetes 1.11, critical pods (except DaemonSet pods,
which are still scheduled by the DaemonSet controller) rely on scheduler
preemption to be scheduled when a cluster is under resource pressure. For this
reason, you will need to run an older version of Rescheduler if you decide to
disable preemption. More on this is provided below. {{< /note >}}
#### Option 1: Disable both Pod priority and preemption
Disabling Pod priority disables preemption as well. In order to disable Pod
Priority, set the feature to false for API server, Scheduler, and Kubelet.
Disabling the feature on Kubelets is not vital. You can leave the feature on for
Kubelets if rolling out is hard.
```
--feature-gates=PodPriority=false
```
#### Option 2: Disable Preemption only

In Kubernetes 1.11, critical pods (except DaemonSet pods, which are
still scheduled by the DaemonSet controller) rely on scheduler preemption to be
scheduled when a cluster is under resource pressure. For this reason, you will
need to run an older version of Rescheduler if you decide to disable preemption.

In Kubernetes 1.11 and later, preemption is controlled by a kube-scheduler flag
`disablePreemption`, which is set to `false` by default.

Preemption does not necessarily remove all lower-priority
Pods. If the pending Pod can be scheduled by removing fewer than all
lower-priority Pods, then only a portion of the lower-priority Pods are removed.
