Using quotas to restrict or track resource usage

Quotas provide a way to restrict or track the disk space and number of files used by a user, group, or qtree. Quotas are applied to a specific FlexVol volume or qtree.

  • 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.
  • Setting up quotas on an SVM
    To set up quotas on a new storage virtual machine (SVM, formerly known as Vserver ), you must create a quota policy, add quota policy rules to the policy, assign the policy to the SVM, and initialize quotas on each FlexVol volume on the SVM.
  • Modifying (or Resizing) quota limits
    When you make changes to the size of existing quotas, you can resize the quotas on all affected volumes, which is faster than reinitializing quotas on those volumes.
  • Reinitializing quotas after making extensive changes
    When you make extensive changes to existing quotas; for example, by adding or deleting quotas for targets that have no enforced quotas— you must make the changes and re-initialize quotas on all affected volumes.
  • Commands to manage quota rules and quota policies
    You can use the volume quota policy rule commands to configure quota rules, and use the volume quota policy commands and some vserver commands to configure quota policies.
  • Commands to activate and modify quotas
    You can use the volume quota commands to change the state of quotas and configure message logging of quotas.
