File system quotas

You can set quotas on a file system from the File > File System > [file system] > Quotas card.

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 create quotas for read-only file systems.

Quotas are supported on SMB, NFS, FTP, NDMP, and multiprotocol file systems.

You can set the following types of quotas for a file system.

Type Description
User quotas Limits the amount of storage that is consumed by an individual user storing data on the file system.
Tree quota Tree quotas limit the total amount of storage that is consumed on a specific directory tree. You can use tree quotas to:
  • Set storage limits on a project basis. For example, you can establish tree quotas for a project directory that has multiple users sharing and creating files in it.
  • Track directory usage by setting the tree quota hard and soft limits to 0 (zero).
NOTE:If you change the limits for a tree quota, the changes take effect immediately without disrupting file system operations.
User quota on a quota tree Limits the amount of storage that is consumed by an individual user storing data on the quota tree.

Quota limits

To track space consumption without setting limits, set Soft Limit and Hard Limit to 0, which indicates no limit.

Type Descriptions
Hard A hard limit is an absolute limit on storage usage.

If a hard limit is reached for a user quota on a file system or quota tree, the user cannot write data to the file system or tree until more space becomes available. If a hard limit is reached for a quota tree, no user can write data to the tree until more space becomes available.

Soft limit A soft limit is a preferred limit on storage usage.

The user is allowed to use space until a grace period has been reached.

The user is alerted when the soft limit is reached, until the grace period is over. After that, an out of space condition is reached until the user gets back under the soft limit.

Quota grace period

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 cannot 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.
