Drive Usage

Use a remote terminal to log in to the server where the instruction stream cloud phone is deployed as the instruction stream cloud phone O&M user (for example, root).
Run the following command to switch to the root user:
```
su - root
```
Run the following command to check the drive usage of the instruction stream cloud phone server:
```
df -h
```
In the preceding figure, the instruction stream cloud phone container data is stored in /home/mount/data/. The contents in the red box show the data storage information of container kbox_1. The storage size is 16G, and the current usage is 1%. If the value of Use% is less than or equal to 85%, the drive usage is normal. Otherwise, you need to clear the drive space.
