Understanding quota reports

Detailed information about the ID and Quota Specifier fields

Factors affecting the contents of the fields  

The information contained in the ID and Quota Specifier fields can vary according to these factors:

• Type of user-UNIX or Windows-to which a quota applies.
• The specific command used to generate the quota report.

Contents of the ID field  

In general, the ID field of the quota report displays a user name instead of a UID or SID. There are, however, the following exceptions:

• For a quota with a UNIX user as the target, the ID field shows the UID instead of a name if no user name for the UID is found in the password database.
• For a quota with a Windows user as the target, the ID field shows the SID instead of a name if either of the following conditions applies:
  • The SID is specified as a quota target and the SID no longer corresponds to a user name.
  • The filer cannot find an entry for the SID in the SID-to-name map cache and cannot connect to the domain controller to determine the user name for the SID when it generates the quota report.

Formats available for the fields  

The information in the ID and Quota Specifier fields is available in three formats:

• A default format generated by the quota report command
• An enhanced format generated by the quota report -u command
• An enhanced format generated by the quota report -x command

Default format  

The quota report command without options generates the default format for the ID and Quota Specifier fields.

The ID field

If a quota target contains only one ID, the ID field displays that ID. Otherwise, the ID field displays one of the IDs from the list.

The ID field displays information in the following formats:

• For a Windows name, the first seven characters of the user name with a preceding backslash are displayed. The domain name is omitted.
• For a SID, the last eight characters are displayed.

The Quota Specifier field

The Quota Specifier field displays an ID that matches the ID field. The ID is displayed the same way the quota target is specified in the /etc/quotas file.

Examples

The following table shows what is displayed in the ID and Quota Specifier fields based on the quota target in the /etc/quotas file.

Enhanced format with quota report -u  

The quota report -u command is useful if you have quota targets that are multiple IDs. It provides more information in the ID and Quota Specifier fields than the default format.

The ID field

The ID field displays all the IDs listed in the quota target of a user quota in the following format:

• On the first line, the format is the same as the default format.
• Each additional name in the quota target is displayed on a separate line in its entirety.

The Quota Specifier field

The Quota Specifier field displays the same list of IDs as specified in the quota target.

Example

The following table shows what is displayed in the ID and Quota Specifier fields based on the quota target in the /etc/quotas file. In this example, the SID maps to the user name NT\js.

Enhanced format with quota report -x  

The quota report -x command is applicable if you have quota targets that are multiple IDs. It provides information in the ID and Quota Specifier fields that can be scanned by a script.

Fields in this quota report format are separated by a tab.

The ID field

The ID field displays all the IDs listed in the quota target of a user quota in the following format:

• The IDs are in a comma-separated list.
• Each ID is displayed in its entirety.

The Quota Specifier field

The Quota Specifier field displays the same list of IDs as specified in the quota target.

Example

The following table shows what is displayed in the ID and Quota Specifier fields based on the quota target in the /etc/quotas file. In this example, the SID maps to the user name NT\js.
