Storage quotas

You can configure user storage quotas on your file systems to limit how much data storage that users can consume. After you set quotas, you can track quota status to monitor usage and see when users surpass their quotas.

You can also enforce quotas by stopping users who reach their quotas from writing to the storage space. When you enforce quotas, a user that exceeds their quota receives an "insufficient disk space" error message.

You can set these thresholds for quota settings:

You can configure default quotas that are applied to new users who access a file system and quotas that apply to specific users or groups. You can also view a report of how much storage each user or group is consuming and whether they're surpassing their quotas.

Storage consumption at a user level is tracked based on file ownership. Storage consumption is calculated using logical file size, not the actual physical storage space that files occupy. User storage quotas are tracked at the time when data is written to a file.

Updating quotas for multiple users requires either running the update command once for each user, or organizing the users into a group and updating the quota for that group.

Managing user storage quotas

You can manage user storage quotas on your file system using the Amazon FSx CLI for remote management on PowerShell. To learn how to use this CLI, see Getting started with the Amazon FSx CLI for remote management on PowerShell.

Following are commands that you can use to manage user storage quotas.

The online help for each command provides a reference of all command options. To access this help, run the command with -?, for example Enable-FSxUserQuotas -?.
