CreateAccessPoint

$result = $client->createAccessPoint([/* ... */]);
$promise = $client->createAccessPointAsync([/* ... */]);

Creates an EFS access point. An access point is an application-specific view into an EFS file system that applies an operating system user and group, and a file system path, to any file system request made through the access point. The operating system user and group override any identity information provided by the NFS client. The file system path is exposed as the access point's root directory. Applications using the access point can only access data in the application's own directory and any subdirectories. To learn more, see Mounting a file system using EFS access points.

This operation requires permissions for the elasticfilesystem:CreateAccessPoint action.

Access points can be tagged on creation. If tags are specified in the creation action, IAM performs additional authorization on the elasticfilesystem:TagResource action to verify if users have permissions to create tags. Therefore, you must grant explicit permissions to use the elasticfilesystem:TagResource action. For more information, see Granting permissions to tag resources during creation.

Errors

BadRequest:

Returned if the request is malformed or contains an error such as an invalid parameter value or a missing required parameter.

AccessPointAlreadyExists:

Returned if the access point that you are trying to create already exists, with the creation token you provided in the request.

IncorrectFileSystemLifeCycleState:

Returned if the file system's lifecycle state is not "available".

InternalServerError:

Returned if an error occurred on the server side.

FileSystemNotFound:

Returned if the specified FileSystemId value doesn't exist in the requester's Amazon Web Services account.

AccessPointLimitExceeded:

Returned if the Amazon Web Services account has already created the maximum number of access points allowed per file system. For more informaton, see https://docs.aws.amazon.com/efs/latest/ug/limits.html#limits-efs-resources-per-account-per-region.

ThrottlingException:

CreateFileSystem

$result = $client->createFileSystem([/* ... */]);
$promise = $client->createFileSystemAsync([/* ... */]);

Creates a new, empty file system. The operation requires a creation token in the request that Amazon EFS uses to ensure idempotent creation (calling the operation with same creation token has no effect). If a file system does not currently exist that is owned by the caller's Amazon Web Services account with the specified creation token, this operation does the following:

• Creates a new, empty file system. The file system will have an Amazon EFS assigned ID, and an initial lifecycle state creating.

• Returns with the description of the created file system.

Otherwise, this operation returns a FileSystemAlreadyExists error with the ID of the existing file system.

The idempotent operation allows you to retry a CreateFileSystem call without risk of creating an extra file system. This can happen when an initial call fails in a way that leaves it uncertain whether or not a file system was actually created. An example might be that a transport level timeout occurred or your connection was reset. As long as you use the same creation token, if the initial call had succeeded in creating a file system, the client can learn of its existence from the FileSystemAlreadyExists error.

For more information, see Creating a file system in the Amazon EFS User Guide.

This operation accepts an optional PerformanceMode parameter that you choose for your file system. We recommend generalPurpose performance mode for all file systems. File systems using the maxIO mode is a previous generation performance type that is designed for highly parallelized workloads that can tolerate higher latencies than the General Purpose mode. Max I/O mode is not supported for One Zone file systems or file systems that use Elastic throughput.

The performance mode can't be changed after the file system has been created. For more information, see Amazon EFS performance modes.

You can set the throughput mode for the file system using the ThroughputMode parameter.

After the file system is fully created, Amazon EFS sets its lifecycle state to available, at which point you can create one or more mount targets for the file system in your VPC. For more information, see CreateMountTarget. You mount your Amazon EFS file system on an EC2 instances in your VPC by using the mount target. For more information, see Amazon EFS: How it Works.

This operation requires permissions for the elasticfilesystem:CreateFileSystem action.

File systems can be tagged on creation. If tags are specified in the creation action, IAM performs additional authorization on the elasticfilesystem:TagResource action to verify if users have permissions to create tags. Therefore, you must grant explicit permissions to use the elasticfilesystem:TagResource action. For more information, see Granting permissions to tag resources during creation.

CreateMountTarget

$result = $client->createMountTarget([/* ... */]);
$promise = $client->createMountTargetAsync([/* ... */]);

Creates a mount target for a file system. You can then mount the file system on EC2 instances by using the mount target.

You can create one mount target in each Availability Zone in your VPC. All EC2 instances in a VPC within a given Availability Zone share a single mount target for a given file system. If you have multiple subnets in an Availability Zone, you create a mount target in one of the subnets. EC2 instances do not need to be in the same subnet as the mount target in order to access their file system.

You can create only one mount target for a One Zone file system. You must create that mount target in the same Availability Zone in which the file system is located. Use the AvailabilityZoneName and AvailabiltyZoneId properties in the DescribeFileSystems response object to get this information. Use the subnetId associated with the file system's Availability Zone when creating the mount target.

For more information, see Amazon EFS: How it Works.

To create a mount target for a file system, the file system's lifecycle state must be available. For more information, see DescribeFileSystems.

In the request, provide the following:

• The file system ID for which you are creating the mount target.

• A subnet ID, which determines the following:

  • The VPC in which Amazon EFS creates the mount target

  • The Availability Zone in which Amazon EFS creates the mount target

  • The IP address range from which Amazon EFS selects the IP address of the mount target (if you don't specify an IP address in the request)

After creating the mount target, Amazon EFS returns a response that includes, a MountTargetId and an IpAddress. You use this IP address when mounting the file system in an EC2 instance. You can also use the mount target's DNS name when mounting the file system. The EC2 instance on which you mount the file system by using the mount target can resolve the mount target's DNS name to its IP address. For more information, see How it Works: Implementation Overview.

Note that you can create mount targets for a file system in only one VPC, and there can be only one mount target per Availability Zone. That is, if the file system already has one or more mount targets created for it, the subnet specified in the request to add another mount target must meet the following requirements:

• Must belong to the same VPC as the subnets of the existing mount targets

• Must not be in the same Availability Zone as any of the subnets of the existing mount targets

If the request satisfies the requirements, Amazon EFS does the following:

• Creates a new mount target in the specified subnet.

• Also creates a new network interface in the subnet as follows:

  • If the request provides an IpAddress, Amazon EFS assigns that IP address to the network interface. Otherwise, Amazon EFS assigns a free address in the subnet (in the same way that the Amazon EC2 CreateNetworkInterface call does when a request does not specify a primary private IP address).

  • If the request provides SecurityGroups, this network interface is associated with those security groups. Otherwise, it belongs to the default security group for the subnet's VPC.

  • Assigns the description Mount target fsmt-id for file system fs-id where fsmt-id is the mount target ID, and fs-id is the FileSystemId.

  • Sets the requesterManaged property of the network interface to true, and the requesterId value to EFS.

  Each Amazon EFS mount target has one corresponding requester-managed EC2 network interface. After the network interface is created, Amazon EFS sets the NetworkInterfaceId field in the mount target's description to the network interface ID, and the IpAddress field to its address. If network interface creation fails, the entire CreateMountTarget operation fails.

We recommend that you create a mount target in each of the Availability Zones. There are cost considerations for using a file system in an Availability Zone through a mount target created in another Availability Zone. For more information, see Amazon EFS. In addition, by always using a mount target local to the instance's Availability Zone, you eliminate a partial failure scenario. If the Availability Zone in which your mount target is created goes down, then you can't access your file system through that mount target.

This operation requires permissions for the following action on the file system:

• elasticfilesystem:CreateMountTarget

This operation also requires permissions for the following Amazon EC2 actions:

• ec2:DescribeSubnets

• ec2:DescribeNetworkInterfaces

• ec2:CreateNetworkInterface

CreateReplicationConfiguration

$result = $client->createReplicationConfiguration([/* ... */]);
$promise = $client->createReplicationConfigurationAsync([/* ... */]);

Creates a replication configuration that replicates an existing EFS file system to a new, read-only file system. For more information, see Amazon EFS replication in the Amazon EFS User Guide. The replication configuration specifies the following:

• Source file system – The EFS file system that you want replicated. The source file system cannot be a destination file system in an existing replication configuration.

• Amazon Web Services Region – The Amazon Web Services Region in which the destination file system is created. Amazon EFS replication is available in all Amazon Web Services Regions in which EFS is available. The Region must be enabled. For more information, see Managing Amazon Web Services Regions in the Amazon Web Services General Reference Reference Guide.

• Destination file system configuration – The configuration of the destination file system to which the source file system will be replicated. There can only be one destination file system in a replication configuration.

  Parameters for the replication configuration include:

  • File system ID – The ID of the destination file system for the replication. If no ID is provided, then EFS creates a new file system with the default settings. For existing file systems, the file system's replication overwrite protection must be disabled. For more information, see Replicating to an existing file system.

  • Availability Zone – If you want the destination file system to use One Zone storage, you must specify the Availability Zone to create the file system in. For more information, see EFS file system types in the Amazon EFS User Guide.

  • Encryption – All destination file systems are created with encryption at rest enabled. You can specify the Key Management Service (KMS) key that is used to encrypt the destination file system. If you don't specify a KMS key, your service-managed KMS key for Amazon EFS is used.

    After the file system is created, you cannot change the KMS key.

For new destination file systems, the following properties are set by default:

• Performance mode - The destination file system's performance mode matches that of the source file system, unless the destination file system uses EFS One Zone storage. In that case, the General Purpose performance mode is used. The performance mode cannot be changed.

• Throughput mode - The destination file system's throughput mode matches that of the source file system. After the file system is created, you can modify the throughput mode.

• Lifecycle management – Lifecycle management is not enabled on the destination file system. After the destination file system is created, you can enable lifecycle management.

• Automatic backups – Automatic daily backups are enabled on the destination file system. After the file system is created, you can change this setting.

For more information, see Amazon EFS replication in the Amazon EFS User Guide.

CreateTags

$result = $client->createTags([/* ... */]);
$promise = $client->createTagsAsync([/* ... */]);

DEPRECATED - CreateTags is deprecated and not maintained. To create tags for EFS resources, use the API action.

Creates or overwrites tags associated with a file system. Each tag is a key-value pair. If a tag key specified in the request already exists on the file system, this operation overwrites its value with the value provided in the request. If you add the Name tag to your file system, Amazon EFS returns it in the response to the DescribeFileSystems operation.

DeleteFileSystem

$result = $client->deleteFileSystem([/* ... */]);
$promise = $client->deleteFileSystemAsync([/* ... */]);

Deletes a file system, permanently severing access to its contents. Upon return, the file system no longer exists and you can't access any contents of the deleted file system.

You need to manually delete mount targets attached to a file system before you can delete an EFS file system. This step is performed for you when you use the Amazon Web Services console to delete a file system.

You can't delete a file system that is in use. That is, if the file system has any mount targets, you must first delete them. For more information, see DescribeMountTargets and DeleteMountTarget.

DeleteMountTarget

$result = $client->deleteMountTarget([/* ... */]);
$promise = $client->deleteMountTargetAsync([/* ... */]);

Deletes the specified mount target.

This operation forcibly breaks any mounts of the file system by using the mount target that is being deleted, which might disrupt instances or applications using those mounts. To avoid applications getting cut off abruptly, you might consider unmounting any mounts of the mount target, if feasible. The operation also deletes the associated network interface. Uncommitted writes might be lost, but breaking a mount target using this operation does not corrupt the file system itself. The file system you created remains. You can mount an EC2 instance in your VPC by using another mount target.

This operation requires permissions for the following action on the file system:

• elasticfilesystem:DeleteMountTarget

DescribeFileSystems

$result = $client->describeFileSystems([/* ... */]);
$promise = $client->describeFileSystemsAsync([/* ... */]);

Returns the description of a specific Amazon EFS file system if either the file system CreationToken or the FileSystemId is provided. Otherwise, it returns descriptions of all file systems owned by the caller's Amazon Web Services account in the Amazon Web Services Region of the endpoint that you're calling.

When retrieving all file system descriptions, you can optionally specify the MaxItems parameter to limit the number of descriptions in a response. This number is automatically set to 100. If more file system descriptions remain, Amazon EFS returns a NextMarker, an opaque token, in the response. In this case, you should send a subsequent request with the Marker request parameter set to the value of NextMarker.

To retrieve a list of your file system descriptions, this operation is used in an iterative process, where DescribeFileSystems is called first without the Marker and then the operation continues to call it with the Marker parameter set to the value of the NextMarker from the previous response until the response has no NextMarker.

The order of file systems returned in the response of one DescribeFileSystems call and the order of file systems returned across the responses of a multi-call iteration is unspecified.

This operation requires permissions for the elasticfilesystem:DescribeFileSystems action.

PutFileSystemPolicy

$result = $client->putFileSystemPolicy([/* ... */]);
$promise = $client->putFileSystemPolicyAsync([/* ... */]);

Applies an Amazon EFS FileSystemPolicy to an Amazon EFS file system. A file system policy is an IAM resource-based policy and can contain multiple policy statements. A file system always has exactly one file system policy, which can be the default policy or an explicit policy set or updated using this API operation. EFS file system policies have a 20,000 character limit. When an explicit policy is set, it overrides the default policy. For more information about the default file system policy, see Default EFS File System Policy.

This operation requires permissions for the elasticfilesystem:PutFileSystemPolicy action.

Parameter Syntax

$result = $client->putFileSystemPolicy([
    'BypassPolicyLockoutSafetyCheck' => true || false,
    'FileSystemId' => '<string>', // REQUIRED

PutLifecycleConfiguration

$result = $client->putLifecycleConfiguration([/* ... */]);
$promise = $client->putLifecycleConfigurationAsync([/* ... */]);

Use this action to manage storage for your file system. A LifecycleConfiguration consists of one or more LifecyclePolicy objects that define the following:

• TransitionToIA – When to move files in the file system from primary storage (Standard storage class) into the Infrequent Access (IA) storage.

• TransitionToArchive – When to move files in the file system from their current storage class (either IA or Standard storage) into the Archive storage.

  File systems cannot transition into Archive storage before transitioning into IA storage. Therefore, TransitionToArchive must either not be set or must be later than TransitionToIA.

  The Archive storage class is available only for file systems that use the Elastic Throughput mode and the General Purpose Performance mode.

• TransitionToPrimaryStorageClass – Whether to move files in the file system back to primary storage (Standard storage class) after they are accessed in IA or Archive storage.

For more information, see Managing file system storage.

Each Amazon EFS file system supports one lifecycle configuration, which applies to all files in the file system. If a LifecycleConfiguration object already exists for the specified file system, a PutLifecycleConfiguration call modifies the existing configuration. A PutLifecycleConfiguration call with an empty LifecyclePolicies array in the request body deletes any existing LifecycleConfiguration. In the request, specify the following:

• The ID for the file system for which you are enabling, disabling, or modifying Lifecycle management.

• A LifecyclePolicies array of LifecyclePolicy objects that define when to move files to IA storage, to Archive storage, and back to primary storage.

  Amazon EFS requires that each LifecyclePolicy object have only have a single transition, so the LifecyclePolicies array needs to be structured with separate LifecyclePolicy objects. See the example requests in the following section for more information.

This operation requires permissions for the elasticfilesystem:PutLifecycleConfiguration operation.

To apply a LifecycleConfiguration object to an encrypted file system, you need the same Key Management Service permissions as when you created the encrypted file system.

Parameter Syntax

$result = $client->putLifecycleConfiguration([
    'FileSystemId' => '<string>', // REQUIRED
    'LifecyclePolicies' => [ // REQUIRED
        [
