> Kubernetes v1.24 introduced an alpha quality implementation of improvements for handling a non-graceful node shutdown. In Kubernetes v1.26, this feature moves to beta. This feature allows stateful workloads to failover to a different node after the original node is shut down or in a non-recoverable state, such as the hardware failure or broken OS.

> In a Kubernetes cluster, it is possible for a node to shut down. This could happen either in a planned way or it could happen unexpectedly. You may plan for a security patch, or a kernel upgrade and need to reboot the node, or it may shut down due to preemption of VM instances. A node may also shut down due to a hardware failure or a software problem.
> To trigger a node shutdown, you could run a shutdown or poweroff command in a shell, or physically press a button to power off a machine.
> A node shutdown could lead to workload failure if the node is not drained before the shutdown.
> In the following, we will describe what is a graceful node shutdown and what is a non-graceful node shutdown.
