Container for the parameters to the DetachVolume operation. 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 can result in the volume becoming stuck in the busy state while detaching. If this happens, detachment can be delayed indefinitely until you unmount the volume, force detachment, reboot the instance, or all three. If an 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 Amazon Web Services Marketplace product code is detached from an instance, the product code is no longer associated with the instance.

You can't detach or force detach volumes that are attached to Amazon ECS or Fargate tasks. Attempting to do this results in the UnsupportedOperationException exception with the Unable to detach volume attached to ECS tasks error message.

For more information, see Detach an Amazon EBS volume in the Amazon EBS User Guide.

Syntax

public class DetachVolumeRequest : AmazonEC2Request

The DetachVolumeRequest type exposes the following members

Constructors

NameDescription
Public Method DetachVolumeRequest()

Empty constructor used to set properties independently even when a simple constructor is available

Public Method DetachVolumeRequest(string)

Instantiates DetachVolumeRequest with the parameterized properties

Properties

NameTypeDescription
Public Property Device System.String

Gets and sets the property Device.

The device name.

Public Property Force System.Boolean

Gets and sets the property Force.

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.

Public Property InstanceId System.String

Gets and sets the property InstanceId.

The ID of the instance. If you are detaching a Multi-Attach enabled volume, you must specify an instance ID.

Public Property VolumeId System.String

Gets and sets the property VolumeId.

The ID of the volume.

Examples

This example detaches the volume (``vol-049df61146c4d7901``) from the instance it is attached to.

To detach a volume from an instance


var client = new AmazonEC2Client();
var response = client.DetachVolume(new DetachVolumeRequest 
{
    VolumeId = "vol-1234567890abcdef0"
});

DateTime attachTime = response.AttachTime;
string device = response.Device;
string instanceId = response.InstanceId;
string state = response.State;
string volumeId = response.VolumeId;
