Before you can access the data in an Apsara File Storage NAS file system, you must
create the 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.
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 General-purpose NAS File System.
- In the Create General-purpose NAS File System panel, configure the parameters. The following table describes the parameters. For
the parameters that are not described in the following table, select values based
on your business requirements or use the default values.
Parameter |
Description |
Region |
Select China (Hangzhou) from the drop-down list.
|
Zone |
Select Hangzhou Zone B. Select the zone where the ECS instance resides.
|
Protocol |
Select SMB.

Select a vSwitch that resides in the VPC. |
- Click Buy Now and follow the on-screen instructions to complete the payment.
- Go to the NAS console. In the left-side navigation pane, choose and click the name of the file system that you created.
- On the details page of the file system, click Mount Targets.
- On the Mount Targets tab, click Mount a file system on ECS by running the command to copy the mount command for later use.
Step 2: Mount the file system
- Connect to the ECS instance. For more information, see Connection methods.
- Open the Command Prompt and run the following command to grant the client anonymous
access permissions:
REG ADD HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\LanmanWorkstation\Parameters /f /v AllowInsecureGuestAuth /t REG_DWORD /d 1
- Enable the Workstation service.
- Press
Win+R
. In the Run dialog box, enter services.msc
and click OK.
- Make sure that the Workstation service is in the Started state and the startup type is Automatic.
- Enable the TCP/IP NetBIOS Helper service.
- Open Control Panel, choose , and then click the network that is connected to your host.
- In the Status dialog box, click Properties. In the Properties dialog box, double-click Internet Protocol Version 4 (TCP/IPv4).
- In the Internet Protocol Version 4 (TCP/IPv4) Properties dialog box, click Advanced.
- In the Advanced TCP/IP Settings dialog box, click the WINS tab, select Enable NetBIOS over TCP/IP, and then click OK.
- Press
Win+R
. In the Run dialog box, enter services.msc
and click OK.
- Make sure that the TCP/IP NetBIOS Helper service is in the Started state and the startup type is Automatic.
- Open the Command Prompt and run the mount command that you copied in Step 1.
- After the mount command is executed, run the
net use
command to verify the mount results.
If the output that is similar to the following information appears, the mount is successful.

If the file system fails to be mounted, troubleshoot the issue. For more information,
see
Fix mount issues.
Step 3: Upload and download data
After you mount the file system on the ECS instance, you can access the file system
the same way you access a local directory. The following figure shows an example.
