Set Fileset Quota to Control Capacity & File Count Limits - Cloud Parallel File Storage - Alibaba Cloud - Cloud Parallel File Storage

Sets a quota for a fileset.

Operation description

Only CPFS for Lingjun 2.7.0 and later support setting quotas for filesets.
The minimum fileset capacity quota is 10 GiB, and the capacity is increased in increments of 1 GiB.
A fileset supports up to 10 billion files or directories. The minimum value is 10,000, and the value is increased in increments of 1.
When you modify a directory quota, the quota capacity or file count must be greater than the used capacity or file count.
Specify at least one of the capacity limit and file count limit.
Quota statistics have a 15-minute delay. The actual usage takes effect 15 minutes later.

RAM authorization

The table below describes the authorization required to call this API. You can define it in a Resource Access Management (RAM) policy. The table's columns are detailed below:

Action: The actions can be used in the Action element of RAM permission policy statements to grant permissions to perform the operation.
API: The API that you can call to perform the action.
Access level: The predefined level of access granted for each API. Valid values: create, list, get, update, and delete.
Resource type: The type of the resource that supports authorization to perform the action. It indicates if the action supports resource-level permission. The specified resource must be compatible with the action. Otherwise, the policy will be ineffective.
- For APIs with resource-level permissions, required resource types are marked with an asterisk (*). Specify the corresponding Alibaba Cloud Resource Name (ARN) in the Resource element of the policy.
- For APIs without resource-level permissions, it is shown as All Resources. Use an asterisk (*) in the Resource element of the policy.
Condition key: The condition keys defined by the service. The key allows for granular control, applying to either actions alone or actions associated with specific resources. In addition to service-specific condition keys, Alibaba Cloud provides a set of common condition keys applicable across all RAM-supported services.
Dependent action: The dependent actions required to run the action. To complete the action, the RAM user or the RAM role must have the permissions to perform all dependent actions.

Request parameters

Parameter	Type	Required	Description	Example
FileSystemId	string	Yes	The ID of the CPFS for Lingjun file system. The ID must start with `bmcpfs-`, such as bmcpfs-290w65p03ok64ya**. You can call DescribeFileSystems (FileSystemType=bmcpfs) to query existing file systems. Note** CPFS for Lingjun file systems with the bmcpfs- prefix cannot be created by calling the CreateFileSystem operation. You must create them in the console.	bmcpfs-290w65p03ok64ya****
FsetId	string	Yes	Fileset ID。	fset-1902718ea0ae****
DryRun	boolean	No	Specifies whether to perform a dry run for this request. A dry run checks parameter validity and dependencies without actually deleting the instance or incurring fees. Valid values: true: Sends a dry run request without deleting the export directory. The check items include required parameters, request format, and business limit dependencies. If the check fails, the corresponding error is returned. If the check passes, HTTP status code 200 is returned. false (default): Sends a normal request. After the check passes, the instance is directly deleted.	false
ClientToken	string	No	The client token that is used to ensure the idempotence of the request. You can use the client to generate the token, but make sure that the token is unique among different requests. The token can contain only ASCII characters and cannot exceed 64 characters in length. For more information, see How to ensure idempotence. Note If you do not specify this parameter, the system automatically uses the RequestId of the API request as the ClientToken. The RequestId may be different for each API request.	123e4567-e89b-12d3-a456-42665544****
FileCountLimit	integer	No	The file count limit for the quota. Valid values: Minimum value: 10,000. Maximum value: 10,000,000,000. Note If this parameter is not specified, the file count is unlimited.	10000
SizeLimit	integer	No	The total capacity limit for the quota. Unit: bytes. Valid values: Minimum value: 10,737,418,240 (10 GiB). Increment: 1,073,741,824 (1 GiB). Note If this parameter is not specified, the capacity is unlimited.	10737418240
