Overview of the quota process
Quotas can be soft or hard. Soft quotas cause ONTAP to send a notification when specified limits are exceeded, and hard quotas prevent a write operation from succeeding when specified limits are exceeded.
About quotas
Quotas provide a way to restrict or track the disk space and number of files used by a user, group, or qtree. You specify quotas using the /etc/quotas file. Quotas are applied to a specific volume or qtree.
Why you use quotas
You can use quotas to limit resource usage in FlexVol volumes, to provide notification when resource usage reaches specific levels, or to track resource usage.
