# 2022-03-18-13:54:09+0800 Add mount options for storageclass

- Cause: https://jira.tidbcloud.com/browse/DM-3753
- Operation:

Run the following script:

``` sh
#!/usr/bin/env bash

cat <<EOF > mount-opts-patch.yaml
mountOptions:
- nodelalloc,noatime
EOF

for ctx in $(kubectl config get-contexts --output=name | grep garden-prod); do
    # switch to the shoot cluster context
    kubectl config use-context ${ctx}

    # only when shoot is not hibernated
    if kubectl version > /dev/null; then
	for sc in $(kubectl get sc --output=name); do
	    if kubectl get ${sc} -oyaml | grep nodelalloc > /dev/null; then
		echo "Skipping ${sc} as it already has the expected mount options"
		continue
	    fi
	    if kubectl get ${sc} -oyaml | grep mountOptions > /dev/null; then
		echo "Skipping ${sc} as it already has mountoptions"
		continue
	    fi
	    echo "kubectl patch ${sc} --patch-file mount-opts-patch.yaml" >> patches.sh
	done
    fi
done
```

After running the script, it will generate the patch script. The `patches.sh` script content is as follows:
