我有一个PDB，可以防止在集群升级过程中驱逐其中一个pod。由于我将PDB的maxUnavailable设置为50%，并且一个pod已经启动并运行。因此另一个pod应该可以被驱逐。它有什么问题？

apiVersion: policy/v1
kind: PodDisruptionBudget
metadata:
  labels:
    group: x
    name: mydeployment
  name: mydeployment-pdb
  namespace: test
spec:
  maxUnavailable: 50%
  selector:
    matchLabels:
      group: x
      name: mydeployment
