Creating or resizing quotas

Ways to change quotas  

You can change quotas in the following ways:

• Create a quota for a quota target that is currently not tracked by your filer. For example, you can add a user quota for jsmith, whose disk usage is currently unrestricted and untracked by any quota.
• Resize a quota that is currently tracked by the filer. You can accomplish the following tasks by quota resizing:
  • Change the size of a quota that has an explicit entry in the /etc/quotas file.
  • Override a derived quota, which does not have an explicit entry in the /etc/quotas file. For example, you can impose a less restrictive quota on a particular user who otherwise is restricted by a default user quota.

You can determine from the quota report whether your filer is tracking disk usage for a particular user, group, or qtree. A quota in the quota report indicates that the filer is tracking the disk space and the number of files owned by the quota target. For more information about quota reports, see Understanding quota reports.

Creating a quota for a quota target that the filer is not tracking  

If currently a user, group, or qtree is not under the effect of any /etc/quotas entry, to create a quota for the user, group, or qtree, complete the following steps.

quota on volume

quota off volume;quota on volume

quota

vol_name: quotas are on

Example

Suppose the /etc/quotas file currently contains the following entry:

jsmith     user@/vol/cad     100M    15K

The following entry applies quotas to quota targets other than jsmith:

*     user@/vol/cad     500M     15K

The following commands activate the newly created entry:

quota off cad;quota on cad

After quota initialization, all users, except for jsmith, are limited to 500 MB of disk space and 15,360 files in the /vol/cad volume.

Resizing an existing quota  

To resize a quota, complete the following steps.

quota resize volume

Example of resizing an explicit quota

Suppose the /etc/quotas file contains the following entry:

jsmith     user@/vol/cad     50M     15K

If you want jsmith to have a more restrictive quota, change the existing entry to the following entry:

jsmith     user@/vol/cad     20M     15K

Then enter the following command:

quota resize cad

The new quota for jsmith goes into effect immediately.

Example of resizing a derived quota

Suppose the /etc/quotas file contains the following entry:

*     user@/vol/cad     50M     15K

If you want jsmith to have a less restrictive quota, add the following explicit quota for jsmith:

jsmith     user@/vol/cad     100M     15K

Then enter the following command:

quota resize cad

The new quota for jsmith goes into effect immediately.

Recommendation after an extensive revision of the /etc/quotas file  

After you edit the /etc/quotas file extensively, it is better to reinitialize quotas than to resize quotas. Although quota reinitalization takes a longer time than quota resizing, quota reinitialization ensures that all quotas listed in the file become effective. Quota resizing works only for quota targets that are currently tracked by Data ONTAP. If your revisions to the /etc/quotas file include entries for quota targets that the filer is not tracking, the quota resize command ignores them. For each entry that it skips, the quota resize command prints the following message:

quota resize: warning: /etc/quotas:n:skipping new entry

n is a line number.
