Turning quotas on and off

What happens when you create a vFiler  

When you create a vFiler, quotas are automatically turned off, on both the hosting filer and the new vFiler, for all the volumes you assign to the new vFiler, and for all volumes from which you assign qtrees to the new vFiler. (Quotas are also turned off for volumes you move from one vFiler to another.)

Example of assigning a qtree to a new vFiler

If quotas have been turned on for the volume /vol/vol1 on the hosting filer vFiler0, and you then assign a qtree in that volume, /vol/vol1/qtree1, to a different vFiler, vFiler1, then the following occurs:

• Quotas are turned off for the entire volume /vol/vol1on vFiler0.
• Turning quotas on again for /vol/vol1 on vFiler0 reapplies quotas for /vol/vol1 as specified in vFiler0's /etc/quotas file, except that user and group quotas no longer apply to qtree1. But any specified qtree quota does apply.
• If you now apply user, group, and qtree quotas to /vol/vol1/qtree1 on vFiler1, these quotas will be enforced along with any qtree quota set from vFiler0 (the more restrictive qtree quota takes precedence).

Prerequisite for turning quotas on and off  

On a hosting filer licensed for vFilers, the hosting filer administrator must allow quotas for a volume before you can turn quotas on and off for the volume. By default, quotas are allowed on all volumes.

Only hosting filer administrators can allow or disallow quotas for a volume.

Effects of disallowing quotas  

Disallowing quotas on a volume has these effects on all vFilers that have storage units in the volume:

• If quotas are currently turned off, you or the vFiler administrator are prevented from turning quotas on for that volume.
• If quotas are currently turned on, they are turned off immediately and are prevented from being turned.

Allowing or disallowing quotas for a volume  

To allow or disallow quotas for a volume, complete the following step.

quota allow | disallow volume 

How turning quotas on and off affects vFilers  

Turning quotas on using the quota on volume command activates quotas on the specified volume based on the contents of /etc/quotas. Changes made to /etc/quotas do not take effect the next time the quota on or quota resize command is executed.

Turning quotas off using the quota off volume command deactivates the specified volume.

You can turn quotas on and off on a per-volume basis for a vFiler. After you turn quotas on for a particular volume, Data ONTAP initializes quotas for the storage units residing on the volume, which are owned by the vFiler. Quota on or off states are persistent and stay set after reboots.

Who can turn quotas on and off?  

Hosting filer administrators and vFiler administrators can turn quotas on and off for a volume as long as they own some storage space in the volume. For example, from the hosting filer, you can turn quotas on for the /vol/vol1 volume if vFiler0, which is the hosting filer, owns some storage space in the volume.

You can turn quotas on and off for a volume from a vFiler regardless of how the quota status for that volume is set from other vFilers, including vFiler0. For example, if vFiler1 owns the /vol/vol1/qtree1 qtree and the hosting filer owns the rest of the /vol/vol1 volume, you can turn quotas on and off from vFiler1 for the volume regardless of whether the hosting filer has quotas on or off for the same volume.

Turning quotas on or off from a vFiler  

To turn quotas on or off for a volume from a vFiler, complete the following step.

vfiler run vfilertemplate quota on |
