This topic describes how to manage file systems in the Apsara File Storage NAS console. In the console, you can create file systems, delete file systems, view a list of the file systems and their details.

Create a file system

  1. Log on to the NAS console.
  2. Log on to the Apsara File Storage NAS console. In the left-side navigation pane, choose NAS > File System List. On the page that appears, click Create File System.
    If you want to create an Extreme NAS file system, click Package Year or Pay-as-you-go in the Extreme NAS section.
  3. In the section, click Pay-as-you-go. On the page that appears, set the required parameters.
    Parameter Description
    Region The region where the file system resides.
    Note If an ECS instance and a file system reside in different regions, the ECS instance cannot access the file system.

    You can create a maximum of 20 file systems in a region by using an Alibaba Cloud account.

    Storage types and protocol types that are supported by NAS change based on the region. For more information, see Regions and supported storage types and protocols.

    Storage Type The storage type. Valid values: Performance and Capacity.

    The maximum size of a Performance NAS file system is 1 PB. The maximum size of a Capacity NAS file system is 10 PB. The pay-as-you-go billing method is adopted.

    Protocol Type The protocol type. Valid values: NFS (including NFSv3 and NFSv4) and SMB (2.1 and later).

    The Network File System (NFS) protocol is suitable for file sharing among Linux ECS instances. The Server Message Block (SMB) protocol is suitable for file sharing among Windows ECS instances.

    Available Zone The zone where the file system resides. Each region consists of multiple zones. Each zone has an independent power supply and network. If a file system and an ECS instance reside in different zones of the same region, they can still communicate with each other.

    Select a zone. We recommend that you select the zone where the ECS instance resides. Otherwise, extra latency may occur if the file system and the ECS instance communicate across zones.

    Storage plan Attach a storage plan if one is available.
    Encryption You can use keys that are hosted by Key Management Service (KMS) to encrypt static data on a file system. For more information, see Encrypt data.
    • This parameter is available only for NFS file systems.
    • You do not need to decrypt data when you read and write it.
    • Valid values: None and Encryption.
  4. Click OK.

View the file system list

On the File System List page, you can view all the file systems in a region. In the File System List, you can modify the name of the file system that you created.

View the details of a file system

Find the file system, and click the file system ID or Management to go to the File System Details page. You can view the basic information, mounting use, and performance monitoring of the file system.

Delete a file system

Before you delete a file system, you must remove all the mount targets of the file system.

Find the file system, move the pointer over More, and clickDelete to delete the file system.

Warning Use caution when you delete a file system. After a file system is deleted, the data on the file system cannot be restored. Ensure that all data is backed up.
