Answer
Drain respects PDBs, uses backoff, ignores DaemonSets/Static Pods, and processes evictions asynchronously.
Quick Answer
kubectl drain cordon the node (stops new scheduling) and evicts Pods. If a Pod has a finalizer that never gets removed (deadlocked controller), it blocks the eviction — the drain hangs. Kubernetes uses a configurable eviction timeout; if exceeded, drain fails. The operator must manually intervene — remove the finalizer or force-delete the stuck Pod.
