View file system user quotas

Network-attached storage is a file-level storage architecture that makes stored data more accessible to networked devices.

About this task

See Understanding PowerMax File for storage systems for an overview of PowerMax File.

You can track and limit drive space consumption by configuring quotas for file systems at the file system or directory level. You can enable or disable quotas at any time, but it is recommended that you enable or disable them during non-peak production hours to avoid impacting file system operations.

NOTE: You cannot enable quotas for read-only file systems.

Quota management allows you to place limits on the amount of space that can be consumed in order to regulate file system storage consumption. User quotas are set at a file system level and limit the amount of space a user may consume on a file system.

The Quota Grace Period provides the ability to set a specific grace period to each tree quota on a file system. The grace period counts down the time between the soft and hard limit, and alerts the user about the time remaining before the hard limit is met. If the grace period expires you can not write to the file system until more space has been added, even if the hard limit has not been met. You can set an expiration date for the Grace Period. The default is 7 days, alternatively you can set the Grace Period expiration date to an infinite amount of time and the Grace Period will never expire, or for specified number of days, hours or minutes. Once the Grace Period expiration date is met, the Grace Period will no longer apply to the File System directory.
