Detaches an EBS volume from an instance. Make sure to unmount any file systems on the device within your operating system before detaching the volume. Failure to do so results in the volume being stuck in a busy state while detaching.

If an Amazon EBS volume is the root device of an instance, it can't be detached while the instance is running. To detach the root volume, stop the instance first.

When a volume with an AWS Marketplace product code is detached from an instance, the product code is no longer associated with the instance.

For more information, see Detaching an Amazon EBS Volume in the Amazon Elastic Compute Cloud User Guide.

See: AWS API Reference for DetachVolume.


Creating a Request

detachVolume Source

Creates a value of DetachVolume with the minimum fields required to make a request.

Use one of the following lenses to modify other fields as desired:

Request Lenses

dvInstanceId :: Lens' DetachVolume (Maybe Text) Source

The ID of the instance.

dvForce :: Lens' DetachVolume (Maybe Bool) Source

Forces detachment if the previous detachment attempt did not occur cleanly (for example, logging into an instance, unmounting the volume, and detaching normally). This option can lead to data loss or a corrupted file system. Use this option only as a last resort to detach a volume from a failed instance. The instance won't have an opportunity to flush file system caches or file system metadata. If you use this option, you must perform file system check and repair procedures.

dvDryRun :: Lens' DetachVolume (Maybe Bool) Source

Checks whether you have the required permissions for the action, without actually making the request, and provides an error response. If you have the required permissions, the error response is DryRunOperation. Otherwise, it is UnauthorizedOperation.

dvVolumeId :: Lens' DetachVolume Text Source

The ID of the volume.

Destructuring the Response

volumeAttachment :: VolumeAttachment Source

Creates a value of VolumeAttachment with the minimum fields required to make a request.

Use one of the following lenses to modify other fields as desired:

Response Lenses

volInstanceId :: Lens' VolumeAttachment (Maybe Text) Source

The ID of the instance.

volDeleteOnTermination :: Lens' VolumeAttachment (Maybe Bool) Source

Indicates whether the EBS volume is deleted on instance termination.

volState :: Lens' VolumeAttachment (Maybe VolumeAttachmentState) Source

The attachment state of the volume.

volAttachTime :: Lens' VolumeAttachment (Maybe UTCTime) Source

The time stamp when the attachment initiated.
