k8s添加节点报[WARNING SystemVerification]: missing optional cgroups: blkio

环境信息：

ubuntu-master01  192.1681.195.128

ubuntu-work01    192.168.195.129

k8s版本 1.25.2

背景描述：初始环境是一个master一个work，后面想扩容两个master节点。当初master01节点初始化成功时输出了一些内容用于节点加入集群的，我保存下来了。

如下：

 1 Your Kubernetes control-plane has initialized successfully!
 2
 3 To start using your cluster, you need to run the following as a regular user:
 4
 5   mkdir -p $HOME/.kube
 6   sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
 7   sudo chown $(id -u):$(id -g) $HOME/.kube/config
 8
 9 Alternatively, if you are the root user, you can run:
10
11   export KUBECONFIG=/etc/kubernetes/admin.conf
12
13 You should now deploy a pod network to the cluster.
14 Run "kubectl apply -f [podnetwork].yaml" with one of the options listed at:
15   https://kubernetes.io/docs/concepts/cluster-administration/addons/
16
17 You can now join any number of the control-plane node running the following command on each as root:
18
19   kubeadm join 192.168.195.128:6443 --token 1s8cnx.dzp9gxk9mhri0px3 \
20         --discovery-token-ca-cert-hash sha256:22c12a103ae84f0f7eeace12ed8d98db392cb42782bfe50a205f73f4013b471a \
21         --control-plane --certificate-key daad49c58ef7ca85acfc65501a06f4179a228925dc149c1086a07cf6754b5b14
22
23 Please note that the certificate-key gives access to cluster sensitive data, keep it secret!
24 As a safeguard, uploaded-certs will be deleted in two hours; If necessary, you can use
25 "kubeadm init phase upload-certs --upload-certs" to reload certs afterward.
26
27 Then you can join any number of worker nodes by running the following on each as root:
28
29 kubeadm join 192.168.195.128:6443 --token 1s8cnx.dzp9gxk9mhri0px3 \
30         --discovery-token-ca-cert-hash sha256:22c12a103ae84f0f7eeace12ed8d98db392cb42782bfe50a205f73f4013b471a

于是，两天后我使用这里的命令添加master2报错如下

网上看了一下原来是我的token过期了，要重新生成才行

root@master01:~# kubeadm init phase upload-certs --upload-certs
[upload-certs] Storing the certificates in Secret "kubeadm-certs" in the "kube-system" Namespace
[upload-certs] Using certificate key:
8e4961700ae059535f4bc60bc64ae9f6e9badb113f4eb2f8d8253a3a0a92b5f3

# 此命令在master节点上执行可以生成一条命令，直接拿到work节点执行，加入到集群中，前提是节点初始化过了
kubeadm token create --print-join-command
kubeadm join 192.168.195.128:6443 --token 2cl24c.zuuuv813otnocq38 --discovery-token-ca-cert-hash sha256:22c12a103ae84f0f7eeace12ed8d98db392cb42782bfe50a205f73f4013b471a

# 所以此处加入master的命令如下

kubeadm join 192.168.195.128:6443 --token 2cl24c.zuuuv813otnocq38 \
   --discovery-token-ca-cert-hash sha256:22c12a103ae84f0f7eeace12ed8d98db392cb42782bfe50a205f73f4013b471a \
   --control-plane --certificate-key 8e4961700ae059535f4bc60bc64ae9f6e9badb113f4eb2f8d8253a3a0a92b5f3
