Quotas can be set for a user or group at the project or filesystem level.
None - No quota is set for this filesystem.
Default - Sets the quota to the default quota at the project level; if no default was set, no quota is set for this filesystem.
Click the radio button, enter a quota in the size field, and select a measurement.
The user and group quota properties are validated separately from the other properties. However, you may only see one validation error if an invalid user/group as well as another invalid property is entered. Correcting one error and applying the changes will show any remaining error messages.
If you see an error message that an invalid property has been entered, it may be an invalid user/group, another invalid property on the page, or both. Fixing one invalid property and then applying the changes will reveal any remaining error messages.
