Special kinds of quotas
You use default, explicit, derived and tracking quotas to manage disk usage in the most efficient manner.
- How default quotas work
You use default quotas to apply a quota to all instances of a given quota type. For example, a default user quota affects all users on the system for the specified volume. In addition, default quotas enable you to modify your quotas easily.
- How you use explicit quotas
You use explicit quotas to specify a quota for a specific quota target, or to override a default quota for a specific target.
- How derived quotas work
A quota applied as a result of a default quota, rather than an explicit entry in the quotas file, is referred to as a derived quota.
- How you use tracking quotas
Tracking quotas generate reports of disk and file usage and do not limit resource usage. When tracking quotas are used, resizing quotas in your quotas file is less disruptive, because you can use the quota resize command. Without tracking quotas, you must turn quotas off and back on to change them.
