# Mount the File System (Linux)

## Step 1: Install the Client

For the installation of the client, please refer to [UPFS Client Install](/docs/upfs/client_install).

## Step 2: Mount the File System

 - If the operation system of mounted cloud host is Ubuntu, the `sudo` command must be used to mount. 

    ```shell
    sudo mount -t upfs <mount_address1>,<mount_address2>/<resource_id>  /path/to/mount 
    ```

 - If the operation system of mounted cloud host is not Ubuntu, use the following command to mount the file system:

    ```shell
    mount -t upfs <mount_address1>,<mount_address2>/<resource_id>  /path/to/mount 
    ```
    Explanation of command line fields:
    
    | Command Line Fields | Explanation                          |
    |----------------------|------------------------------------|
    | ```mount```                | Keyword of mount command              |
    | ```-t upfs```                | Specifies that the type of the file system to mount is UPFS       |
    | ```<mount_address1>,<mount_address2>/<resource_id>``` | File system URL obtained from the DezaiCloud console page (For detailed URL rules, see the File System URL section in [Fundamental Concepts](/docs/upfs/upfs_manual_instruction/concept)) |
    | ```/path/to/mount```              | The local path to which the file system will be mounted. Ensure that this directory is not mounted by other file systems |

    In addition, additional options can be added via -o during mounting (options are separated by commas). All available options are listed below:
    
    | Option Name          | Description                                                      |
    |----------------|--------------------------------------------------------- |
    | ```ro```              | Read-only mode                                                  |
    | ```rw```              | Read-write mode                                            |
    | `level=mini` | Mount with the minimum performance specification, suitable for VMs with 1 CPU core and 2GB of memory |
    | `level=max` | Mount with the standard performance specification |
    | `level=ultra` | Mount with the enhanced performance specification |



    Example:
    
    ```shell
    mount -t upfs 100.64.240.95:10109,100.64.240.97:10109/upfs-yc3ae1gwpwg /mnt  -o ro
    ```

## Step 3: Check Mount Status

Execute the command ```df -h``` to check the status of the mounted file system. If the mount is successful, you will see the UPFS entry for the resource ID, the usage, mount point, and other information.
