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.
When ONTAP receives a request from a user or user group to write to a FlexVol volume, it checks to see whether quotas are activated on that volume for the user or user group and determines the following:
Whether the hard limit will be reached
If yes, the write operation fails when the hard limit is reached and the hard quota notification is sent.
Whether the soft limit will be breached
If yes, the write operation succeeds when the soft limit is breached and the soft quota notification is sent.
Whether a write operation will not exceed the soft limit
If yes, the write operation succeeds and no notification is sent.
