Mount a file system on a Windows ECS instance - Storage Services Overview

Before you can access the data in Apsara File Storage NAS, you must create a NAS file system and mount the file system on an Elastic Compute Service (ECS) instance. This topic describes how to create a Server Message Block (SMB) file system in the NAS console. This topic also describes how to mount the SMB file system on an ECS instance. In this example, the ECS instance is deployed on Windows Server 2019 in a virtual private cloud (VPC). After you mount the file system on the ECS instance, you can upload data to or download data from the file system.

Prerequisites

Apsara File Storage NAS is activated.
If you visit the product page of Apsara File Storage NAS for the first time, follow the instructions on the page to activate the service.
An ECS instance is created in the China (Hangzhou) region. The operating system of the instance is Windows Server 2019. For more information, see Create an instance.

Step 1: Create an SMB file system and create a mount target for the file system

Log on to the NAS console.
In the File System Selection Guide section of the Overview page, click Create a General Purpose NAS File System.

On the buy page of General-purpose NAS file systems, set the required parameters. The following table describes the parameters. For other parameters, select values based on your business requirements or use the default values.


Parameter	Description
Region	Select China (Hangzhou).
Zone	Select Hangzhou Zone B. Select the zone where the ECS instance resides.
Protocol Type	Select SMB.
Network Type	Select VPC.
VPC	Select the VPC where the ECS instance resides.
VSwitch	Select a vSwitch that resides in the VPC.

Step 2: Mount the file system

Connect to the ECS instance. For more information, see Connection methods.

Open the command-line interface and run the following command to allow anonymous access from the client:

REG ADD HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\LanmanWorkstation\Parameters /f /v AllowInsecureGuestAuth /t REG_DWORD /d 1

Enable the Workstation service.
1. Press Win+R. In the Run dialog box, enter services.msc and click OK.
2. Make sure that the Workstation service is in the Started state and the startup type is Automatic.
Enable the TCP/IP NetBIOS Helper service.
1. Open Control Panel, choose Network and Internet > Network and Sharing Center, and then click the network that is connected to your host.
2. In the Status dialog box, click Properties. In the Properties dialog box, double-click Internet Protocol Version 4 (TCP/IPv4).
3. In the Internet Protocol Version 4 (TCP/IPv4) Properties dialog box, click Advanced.
4. In the Advanced TCP/IP Settings dialog box, click the WINS tab, select Enable NetBIOS over TCP/IP, and then click OK.
5. Press Win+R. In the Run dialog box, enter services.msc and click OK.
6. Make sure that the TCP/IP NetBIOS Helper service is in the Started state and the startup type is Automatic.
Open the command-line interface and run the following command to mount the SMB file system:
```
net use D: \\file-system-id.region.nas.aliyuncs.com\myshare
```
The syntax of D: \\file-system-id.region.nas.aliyuncs.com\myshare is <Letter of the local drive>\\<Domain name of the mount target>\myshare. Replace the parameters with the actual values.
Note
- Make sure that <Letter of the local drive> is not set to an existing drive.
- myshare is the name of the shared SMB directory. You cannot change the name.
Run the net use command to check the mount result.

The command output in the following figure indicates a successful mount.
If the file system fails to be mounted, troubleshoot the issue. For more information, see Fix mount issues.

Step 3: Upload data to or download data from the file system

After you mount the file system on the ECS instance, you can use the file system in the same way as a local directory. The following figure shows an example.
