Modifying General Properties of a File System

Modifying General Properties of a File System

You can modify the general properties of a file system.

Prerequisites

At least one file system has been created.

Procedure

  1. Log in to DeviceManager.
  2. Choose Provisioning > File System.
  3. Select a file system whose general properties you want to modify and click Properties.

    The File System Properties page is displayed.

  4. Modify the name and description.

    1. Modify Name.
      NOTE:
      • The name must be unique.
      • For V300R006C00 and V300R006C10, the name can contain only letters, digits, and underscores (_).
      • For V300R006C20 and later versions, the name can contain only letters of any language, digits, and underscores (_).
      • The name can contain 1 to 255 characters.
    2. Modify Description.
    3. Change the file system type in the Type drop-down list.
      • Thin file system:

        A thin file system is configured with an initial capacity when being created and dynamically allocated required storage resources when its available capacity is insufficient.

      • Thick file system:

        A thick file system is allocated a fixed capacity of storage resources according to the capacity specified when being created using the automatic provisioning technology.

      NOTE:
      • The type of clone file systems cannot be changed.
      • For V300R006C30 and earlier versions, the type of file systems enabled with SmartDedupe or SmartCompression cannot be changed.
      • For V300R006C50 and later versions, a thin file system enabled with SmartDedupe or SmartCompression can be changed to a thick one but a thick file system enabled with SmartDedupe or SmartCompression cannot be changed to a thin one.
      • Only storage systems of V300R006C10 and later versions support the file system type change operation.
    4. Modify the snapshot space ratio.
      In the Snapshot Space Ratio (%) text box, enter the ratio of the file system snapshot space to the file system space.
      NOTE:

      The value is an integer ranging from 0 to 50.

    5. Change the security mode in the Security Mode drop-down list. Security Mode only applies to V300R006C60 and later versions.
      • Mixed

        Applies to the scenario in which both CIFS and NFS users can access and control the file system. Either CIFS or NFS permissions are valid. The latest configured permissions prevail.

      • Native

        Applies to the scenario in which Windows NT ACLs control CIFS users' permissions and UNIX mode bits control NFS users' permissions. In this mode, Windows NT ACLs and UNIX mode bits will neither affect nor synchronize with each other.

        • For CIFS share access, the system checks whether a Windows user has the access permission based on the Windows NT ACLs.
        • For NFS share access, the system checks whether a UNIX user has the access permission based on the UNIX mode bits.
    6. Click Apply.

      The Execution Result dialog box is displayed, indicating that the operation succeeded.

    7. Click Close.

  5. Click OK.
