The quota default values define a template with which the system will automatically generate a quota in response to a file being saved on the file system. If a file is saved, and the respective defaults are set, a user quota will be created for the user, and a group quota created for the user's domain. In addition, as soon as the defaults are set, a user and group quota will be created for the owner of the directory at the root of the virtual volume.

  1. Navigate to Home > Storage Management > Quotas by File System to display the Quotas by File System page.
  2. In the Quotas by File System page, click User Defaults or Group Defaults. User Defaults creates a user quota for the user; a Group quota creates a group quota for the user's domain.


    The following table describes the fields on this page:

    Field/Item Description
    EVS/File System The EVS and file system on which the user file system quota applies.
    Virtual Volume name The name given to the virtual volume on creation.
    Created By Describes how the quota was created. The options are:
    • User Defined - created by a user through the NAS Manager or CLI.
    • System Defined - when an NFS or SMB client creates a file in the file system within the path of a virtual volume, and the user- or group-defaults for quotas in that virtual volume are set, a quota is created using the values in the defaults.
    User/Group Account A user or group has an SMB or NFS account. When using NFS, the ID number appears in this field. When using SMB, the AD account name appears in this field.
    Quota Type The type of quota. The options are:
    • Virtual Volume - this quota type limits usage over the whole virtual volume, regardless of who is creating the files.
    • User - this quota type limits the space usable in the virtual volume (or the number of files that can be created) by a single user.
    • Group - this quota type limits the space usable in the virtual volume (or the number of files that can be created) by a whole group.
    Automatically create quotas for Domain Users
    Note: This option only displays on the group file system quota page.
    This option allows the creation of default quotas for the group Domain Users. By default every NT user belongs to the group Domain Users. Enabling this option effectively includes every NT user in the quota, (unless each user's primary group has been explicitly set).
    Usage
    Used The amount of used space in the virtual volume that is being tracked by this quota.
    Limit Amount of space to enable in Bytes: KiB, MiB, GiB, TiB, PiB, or EiB.
    Hard Limit When enabled, the amount of space specified in the Limit field cannot be exceeded.
    Warning Percentage of the amount of space specified in the Limit field at which a Warning alert is sent.
    Severe Percentage of the amount of space specified in the Limit field at which a Severe alert is sent.
    File Count
    Count The number of files in the virtual volume that are being tracked by this quota.
    Limit Maximum number of files to enable for this quota.
    Hard Limit When enabled, the number of files specified in the Limit field cannot be exceeded.
    Warning The percentage of the number of files specified in the Limit field at which a Warning alert is sent.
    Severe Percentage of the amount of space specified in the Limit field at which a Severe alert is sent.
    Log Quota Events in the managed server's Event log Selecting this check box sets the default for all users or groups to have quota events logged in the server’s event log.
  3. For group file system quota defaults, select the Automatically create quotas for Domain Users check box to allow the creation of default quotas for the group domain users.
  4. Under the Usage and File Count sections, enter the values as appropriate:
    1. In the Limit field, enter the limit. Additionally, under Usage, select KiB, MiB, GiB, or TiB from the list.
    2. Select the Hard Limit check box if the space specified in the Limit field cannot be exceeded.
    3. In the Warning field , enter the warning.
    4. In the Severe field, enter the value.
