Understanding quota reports

About quota reports for vFilers

A quota report contains information for the vFiler from which you enter the quota report command.

Example

The /vol/vol1 volume contains two qtrees, one owned by vFiler1 and the other owned by vFiler2. When you display the quota report for vFiler1, only the quota information pertaining to vFiler1 is shown. No information about the qtrees owned by vFiler2 or the hosting filer is included in the quota report.

About quota reports for the hosting filer

When you display a quota report for a hosting filer, it shows

The disk space and the number of files owned by the quota targets in volumes and qtrees that do not belong to vFilers other than vFiler0.
The disk space and the number of files in qtrees owned by other vFilers but that are restricted by tree quotas specified in the filer's /etc/quotas file. Information about users and groups in these qtrees, however, is not shown.

How the filer's tree quota affects the vFiler's quota report

The K-Bytes and Files fields include the limits for disk space and number of files in a qtree. However, if a qtree owned by a vFiler is restricted by the tree quota specified in the filer's /etc/quotas file, the K-Bytes and Files fields in the vFiler's quota report might not reflect the limits that are in effect for these reasons:

If the vFiler does not impose a tree quota on the qtree, the quota report does not include an entry for the qtree, although the qtree is restricted by the tree quota imposed by the filer.
If the vFiler imposes a tree quota on the qtree, the K-Bytes and Files fields in the quota report reflect the limits specified in the vFiler's /etc/quotas file, although the qtree is restricted by the tree quota imposed by the filer.

Example

The /vol/vol1/qtree1 qtree is owned by vFiler1. Suppose the filer's /etc/quotas file specifies that this qtree can use up to 100 GB of disk space, and the vFiler's /etc/quotas file specifies that this qtree can use up to 150 GB of disk space. When you display a quota report for vFiler1, the entry for qtree1 shows that the maximum amount of disk space allowed is 150 GB, even though qtree1 is actually limited by the more restrictive quota, which is 100 GB.

Command for displaying vFiler names in the quota report

The quota report command syntax for a vFiler is the same as the syntax for a filer, except that it also takes the -v argument. If you use the quota report -v command, the report displays the vFiler name before the Quota Specifier field.
