Add Quota Setting

Overview

This function adds a new quota setting information. Drive space and file count thresholds (Warning and Limit) can be set.

Quota is a function that limits drive space or the number of files used on a NAS user volume or a shared folder to prevent the depletion of resources in the storage system.

This function is displayed in a Unified Storage environment.

Maximum Quota Setting Information for Each Model

Model Maximum quota setting information (*1)
ETERNUS DX100 S5 5000
ETERNUS DX200 S5 10000
ETERNUS DX500 S5 15000
ETERNUS DX600 S5 20000
*1  :  The maximum number of quota setting information for this function may be less in some operating environments.
Caution

  • Quotas for NAS user volumes are set for users or groups that are registered in the authentication server. When using this function, registering the users or groups in the authentication server in advance is necessary.

  • Quotas for shared folders are set for shared folders that are registered in the storage system. Create the shared folders in advance. Refer to the [Create Shared Folder] function for details.

  • To configure the quota information for each shared folder to which the NAS user volume belongs where the NAS FS version is "2", "3", or "4", updating the file system version and reconfiguring the file system information are required. Perform the following procedure before setting the quota using this function.

    1. Unmount CIFS and NFS from the client.

    2. Use the [Reconfigure NAS Volume] function to reconfigure the relevant NAS user volume. The NAS FS version is changed to "5".

    3. Unmount the relevant NAS user volume with the "forced nas-fsunmount" CLI command.

    4. Create quota information on the file system with the "start nas-fsck" CLI command. (Select "repair" or "force-repair" for the "mode" parameter.)

    5. Mount the relevant NAS user volume again with the "forced nas-fsmount" CLI command.

    Refer to "ETERNUS CLI User's Guide" for details about each command.

  • When inconsistencies in the quota information occur, restore the quota information by executing the "start nas-fsck" CLI command.

    Refer to "ETERNUS CLI User's Guide" for details.

  • This function sets thresholds (Warning, Limit, or both Warning and Limit) for the drive space or the file count.

    • When exceeding the warning threshold

      This is a predictive notification and writing to the relevant NAS user volume is not prohibited.

    • When exceeding the limit threshold

      Writing to the relevant NAS user volume is prohibited.

  • In each NAS user volume, add a quota setting information to multiple users, groups, and shared folders. Note that the maximum number of quota setting information that can be added in a single operation (by clicking the [Add] button on the bottom of the screen) is 100 regardless of the operating environment.

  • When deleting NAS user volumes, quota setting information assigned to that volume is also deleted at the same time.

  • When deleting shared folders, quota setting information assigned to that shared folder is also deleted at the same time.

Note
  • Event notifications for the conditions described below can be sent using the specified method. Refer to the [Setup Event Notification] function for details.

    • The drive space or the file count has exceeded the threshold

    • The drive space or the file count has returned to a normal state below the threshold value

  • The quota setting information in the storage system can be checked. Refer to the [Quota Management] function for details.

  • The quota setting information in the storage system can be changed. Refer to the [Modify Quota Setting] function for details.

  • The quota setting information in the storage system can be deleted. Refer to the [Delete Quota Setting] function for details.

  • The "NAS FS Version" for the NAS user volume can be checked in the [Volume Detail] screen. Refer to the [Volume (Basic Information)] function for details.

  • Shared folders include home directories.
