Viewing Namespaces

Context

• On the namespace management page, click to refresh namespaces.
• On the namespace management page, click to export a list of namespaces.
• On the namespace management page, click or next to a parameter and enter a keyword or select a parameter value to search for desired namespaces.
• On the namespace management page, click and select desired namespace parameters to be viewed.

Procedure

1. Choose Resources > Resources > Namespace.
2. Select a desired account from the Account drop-down list in the upper left corner.
3. View information about the namespaces for the selected account in the function pane. Table 1 describes related parameters.

   Table 1 Namespace parameters

   Parameter	Description
   Name	Name of a namespace.
   ID	ID of a namespace.
   Data Encryption	Whether to enable data encryption for a namespace. NOTE: Data encryption is supported only after an advanced license is imported.
   Encryption Algorithm	Encryption algorithm used after data encryption is enabled.
   Storage Pool	Storage pool to which a namespace belongs.
   Running Status	Running status of a namespace. The value is Normal.
   Created	Time when a namespace was created.
   Space Quota Usage	Ratio of the size of files written to a namespace to the space hard quota. NOTE: The size of written files is rounded up in the unit of 4 KB.
   File Quantity Quota Usage	Ratio of the number of files written to a namespace to the file quantity hard quota. NOTE: When the protection status of the secondary resource in a remote replication pair is Access prohibited, Space Quota Usage and File Quantity Quota Usage of the corresponding namespace are displayed as -- on DeviceManager. The actual quota usage of the namespace is displayed only when the secondary resource protection status is Read/Write.
   Data Protection	Data protection information of a namespace.
   Snapshot Directory Visibility	Whether the snapshot directory of a namespace is visible.
   Directory Space Display	Display mode of the space occupied by directories or files in a namespace when the ls -l command is executed.
   Redundancy Ratio	Redundancy ratio of a namespace. NOTE: Redundancy Ratio is available only for storage pools that use the EC redundancy policy. For storage pools that use the data copy redundancy policy, this parameter is displayed as --.
   Security Style	Security style of a namespace. Possible options are: Mixed: applies to scenarios where users of CIFS clients (using the SMB protocol) and UNIX clients (using the NFS, HDFS, or DPC protocol) can access and control namespaces. In this style, CIFS permissions (NT ACLs) and UNIX permissions (UNIX mode bits, POSIX ACLs, or NFSv4 ACLs) cannot co-exist. Only the latest configured permissions on either CIFS or UNIX clients take effect. Native: applies to the same scenarios as the Mixed style. The difference between the Native style and the Mixed style is that CIFS permissions (NT ACLs) and UNIX permissions (UNIX mode bits, POSIX ACLs, or NFSv4 ACLs) can co-exist and will neither affect nor synchronize with each other in Native style. NTFS: applies to scenarios where Windows NT ACLs control users' permissions. UNIX: applies to scenarios where UNIX mode bits, POSIX ACLs, or NFSv4 ACLs control users' permissions. NOTE: In Mixed style (which supports NT ACLs), if you configure an NT ACL for a file or directory on a Windows client and switch Mixed to UNIX, the NT ACL in Mixed style will become invalid.
   Case Sensitivity	Whether the name of a file or directory is case sensitive. Case-sensitive: The object and HDFS services are well supported. However, in the protocol interworking scenarios, CIFS case insensitivity is not supported. Case-insensitive: NFS and CIFS are well supported, but some functions of the HDFS and object services are unavailable. For example, results of object listing operations cannot be sorted and returned in sensitive lexicographical order. NOTE: If the file service is disabled, only Case-insensitive is supported. The case sensitivity mode cannot be modified after the namespace creation is complete.
   Automatic Update of Atime	Atime indicates the time when the namespace is accessed. After this function is enabled, the system updates the access time of a namespace based on the value of Update Frequency.
   Update Frequency	Atime update frequency. The value can be Hourly or Daily.
   Recycle Bin	Whether the recycle bin is enabled for a namespace.
   Recycle Bin Directory Visibility	Whether the recycle bin directory is visible. If this parameter is set to Visible, the system displays the .recyclebininternal directory of the namespace and its dtrees.
   Recycle Bin Operation Permission	Select a user who can operate files in the recycle bin. root: Only user root can operate files in the recycle bin. Common user: The system creates a directory for each user based on the user name and user ID. Users have the permission to operate files in their own directories. User root has the permission to operate all users' directories.
   SmartIndexing	Whether metadata indexing is enabled for a namespace.
   Namespace Type	Whether a namespace is the namespace for storing audit log data.
   Audit Log	Whether the audit log function is enabled for a namespace.
   DPC	Whether DPC is enabled for a namespace.
   Standard SmartCompression	Whether to enable standard SmartCompression for a namespace.
   Hot Pool Compression	Whether to enable hot pool compression for a namespace.
   Compression Algorithm	Standard SmartCompression algorithm used by a namespace.

   

   • You can click the name of a namespace to view its general, quota, protocol, protection, and WORM information. Quotas cannot be configured for the namespace if it is an audit log namespace.
   • When the system is being upgraded, the WORM information of the namespace may be incorrect. View the WORM information after the upgrade is complete.
