describe-data-repository-associations

Description

Returns the description of specific Amazon FSx for Lustre data repository associations, if one or more AssociationIds values are provided in the request, or if filters are used in the request. Data repository associations are supported only for file systems with the Persistent_2 deployment type.

You can use filters to narrow the response to include just data repository associations for specific file systems (use the file-system-id filter with the ID of the file system) or data repository associations for a specific repository type (use the data-repository-type filter with a value of S3 ). If you don’t use filters, the response returns all data repository associations owned by your Amazon Web Services account in the Amazon Web Services Region of the endpoint that you’re calling.

When retrieving all data repository associations, you can paginate the response by using the optional MaxResults parameter to limit the number of data repository associations returned in a response. If more data repository associations remain, Amazon FSx returns a NextToken value in the response. In this case, send a later request with the NextToken request parameter set to the value of NextToken from the last response.

Options

--association-ids (list)

IDs of the data repository associations whose descriptions you want to retrieve (String).

(string)

Syntax:

"string" "string" ...

--filters (list)

A list of Filter elements.

(structure)

A filter used to restrict the results of describe calls. You can use multiple filters to return results that meet all applied filter requirements.

Name -> (string)

The name for this filter.

Values -> (list)

The values of the filter. These are all the values for any of the applied filters.

(string)

The value for a filter.

Shorthand Syntax:

Name=string,Values=string,string ...

JSON Syntax:

[
  {
    "Name": "file-system-id"|"backup-type"|"file-system-type"|"volume-id"|"data-repository-type",
    "Values": ["string", ...]
  }
  ...
]

--max-results (integer)

The maximum number of resources to return in the response. This value must be an integer greater than zero.

--next-token (string)

(Optional) Opaque pagination token returned from a previous operation (String). If present, this token indicates from what point you can continue processing the request, where the previous NextToken value left off.

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

See ‘aws help’ for descriptions of global parameters.

Output

Associations -> (list)

An array of one ore more data repository association descriptions.

(structure)

The configuration of a data repository association that links an Amazon FSx for Lustre file system to an Amazon S3 bucket. The data repository association configuration object is returned in the response of the following operations:

• CreateDataRepositoryAssociation

• UpdateDataRepositoryAssociation

• DescribeDataRepositoryAssociations

Data repository associations are supported only for file systems with the Persistent_2 deployment type.

AssociationId -> (string)

The system-generated, unique ID of the data repository association.

ResourceARN -> (string)

The Amazon Resource Name (ARN) for a given resource. ARNs uniquely identify Amazon Web Services resources. We require an ARN when you need to specify a resource unambiguously across all of Amazon Web Services. For more information, see Amazon Resource Names (ARNs) in the Amazon Web Services General Reference .

FileSystemId -> (string)

The globally unique ID of the file system, assigned by Amazon FSx.

Lifecycle -> (string)

Describes the state of a data repository association. The lifecycle can have the following values:

• CREATING - The data repository association between the FSx file system and the S3 data repository is being created. The data repository is unavailable.

• AVAILABLE - The data repository association is available for use.

• MISCONFIGURED - Amazon FSx cannot automatically import updates from the S3 bucket or automatically export updates to the S3 bucket until the data repository association configuration is corrected.

• UPDATING - The data repository association is undergoing a customer initiated update that might affect its availability.

• DELETING - The data repository association is undergoing a customer initiated deletion.

• FAILED - The data repository association is in a terminal state that cannot be recovered.

FailureDetails -> (structure)

Provides detailed information about the data respository if its Lifecycle is set to MISCONFIGURED or FAILED .

Message -> (string)

A detailed error message.

FileSystemPath -> (string)

A path on the file system that points to a high-level directory (such as /ns1/ ) or subdirectory (such as /ns1/subdir/ ) that will be mapped 1-1 with DataRepositoryPath . The leading forward slash in the name is required. Two data repository associations cannot have overlapping file system paths. For example, if a data repository is associated with file system path /ns1/ , then you cannot link another data repository with file system path /ns1/ns2 .

This path specifies where in your file system files will be exported from or imported to. This file system directory can be linked to only one Amazon S3 bucket, and no other S3 bucket can be linked to the directory.

Note

If you specify only a forward slash (/ ) as the file system path, you can link only 1 data repository to the file system. You can only specify “/” as the file system path for the first data repository associated with a file system.

DataRepositoryPath -> (string)

The path to the Amazon S3 data repository that will be linked to the file system. The path can be an S3 bucket or prefix in the format s3://myBucket/myPrefix/ . This path specifies where in the S3 data repository files will be imported from or exported to.

BatchImportMetaDataOnCreate -> (boolean)

A boolean flag indicating whether an import data repository task to import metadata should run after the data repository association is created. The task runs if this flag is set to true .

ImportedFileChunkSize -> (integer)

For files imported from a data repository, this value determines the stripe count and maximum amount of data per file (in MiB) stored on a single physical disk. The maximum number of disks that a single file can be striped across is limited by the total number of disks that make up the file system.

The default chunk size is 1,024 MiB (1 GiB) and can go as high as 512,000 MiB (500 GiB). Amazon S3 objects have a maximum size of 5 TB.

S3 -> (structure)

The configuration for an Amazon S3 data repository linked to an Amazon FSx Lustre file system with a data repository association. The configuration defines which file events (new, changed, or deleted files or directories) are automatically imported from the linked data repository to the file system or automatically exported from the file system to the data repository.

AutoImportPolicy -> (structure)

Specifies the type of updated objects (new, changed, deleted) that will be automatically imported from the linked S3 bucket to your file system.

Events -> (list)

The AutoImportPolicy can have the following event values:

• NEW - Amazon FSx automatically imports metadata of files added to the linked S3 bucket that do not currently exist in the FSx file system.

• CHANGED - Amazon FSx automatically updates file metadata and invalidates existing file content on the file system as files change in the data repository.

• DELETED - Amazon FSx automatically deletes files on the file system as corresponding files are deleted in the data repository.

You can define any combination of event types for your AutoImportPolicy .

(string)

AutoExportPolicy -> (structure)

Specifies the type of updated objects (new, changed, deleted) that will be automatically exported from your file system to the linked S3 bucket.

Events -> (list)

The AutoExportPolicy can have the following event values:

• NEW - Amazon FSx automatically exports new files and directories to the data repository as they are added to the file system.

• CHANGED - Amazon FSx automatically exports changes to files and directories on the file system to the data repository.

• DELETED - Files and directories are automatically deleted on the data repository when they are deleted on the file system.

You can define any combination of event types for your AutoExportPolicy .

(string)

Tags -> (list)

A list of Tag values, with a maximum of 50 elements.

(structure)

Specifies a key-value pair for a resource tag.

Key -> (string)

A value that specifies the TagKey , the name of the tag. Tag keys must be unique for the resource to which they are attached.

Value -> (string)

A value that specifies the TagValue , the value assigned to the corresponding tag key. Tag values can be null and don’t have to be unique in a tag set. For example, you can have a key-value pair in a tag set of finances : April and also of payroll : April .

CreationTime -> (timestamp)

The time that the resource was created, in seconds (since 1970-01-01T00:00:00Z), also known as Unix time.

NextToken -> (string)

(Optional) Opaque pagination token returned from a previous operation (String). If present, this token indicates from what point you can continue processing the request, where the previous NextToken value left off.
