 ### Case#1: volume create/delete issue
  - locate csi driver pod
 ```console
-$ kubectl get po -o wide -n kube-system | grep csi-blob-controller
+kubectl get po -o wide -n kube-system | grep csi-blob-controller
+```
+<pre>
 NAME                                       READY   STATUS    RESTARTS   AGE     IP             NODE

  - get csi driver logs
 ```console
-$ kubectl logs csi-blob-controller-56bfddd689-dh5tk -c blob -n kube-system > csi-blob-controller.log
+kubectl logs csi-blob-controller-56bfddd689-dh5tk -c blob -n kube-system > csi-blob-controller.log
 ```
 > note: there could be multiple controller pods, logs can be taken from all of them simultaneously, also with `follow` (realtime) mode
 > `kubectl logs deploy/csi-blob-controller -c blob -f -n kube-system`
 
 ### Case#2: volume mount/unmount failed
  - locate csi driver pod and make sure which pod do tha actual volume mount/unmount
 ```console
-$ kubectl get po -o wide -n kube-system | grep csi-blob-node
+kubectl get po -o wide -n kube-system | grep csi-blob-node
+```
+<pre>
 NAME                                       READY   STATUS    RESTARTS   AGE     IP             NODE

  - get csi driver logs
 ```console
-$ kubectl logs csi-blob-node-cvgbs -c blob -n kube-system > csi-blob-node.log
+kubectl logs csi-blob-node-cvgbs -c blob -n kube-system > csi-blob-node.log
 ```
+> note: to watch logs in realtime from multiple `csi-blob-node` DaemonSet pods simultaneously, run the command:
+> ```console
+> kubectl logs daemonset/csi-blob-node -c blob -n kube-system -f
+> ```
 
 ### get blobfuse driver version
 ```console
-# kubectl exec -it csi-blob-node-fmbqw -n kube-system -c blob -- sh
-# blobfuse -v
-blobfuse 1.2.4
+kubectl exec -it csi-blob-node-fmbqw -n kube-system -c blob -- sh
+blobfuse -v
 ```
+<pre>
+blobfuse 1.2.4
+</pre>
 
 ### check blobfuse mount on the agent node
 ```console
-# mount | grep blobfuse | uniq
+mount | grep blobfuse | uniq
 ```
