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 AWS 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.
Request Parameters
The following parameters are for this specific action. For more information about required and optional parameters that are common to all actions, see Common Query Parameters.
- Device
-
The device name.
Type: String
Required: No
- DryRun
-
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 isUnauthorizedOperation.Type: Boolean
Required: No
- 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.
Type: Boolean
Required: No
- InstanceId
-
The ID of the instance. If you are detaching a Multi-Attach enabled volume, you must specify an instance ID.
Type: String
Required: No
- VolumeId
-
The ID of the volume.
Type: String
Required: Yes
Response Elements
The following elements are returned by the service.
- associatedResource
-
The ARN of the Amazon ECS or Fargate task to which the volume is attached.
Type: String
- attachTime
-
The time stamp when the attachment initiated.
Type: Timestamp
- deleteOnTermination
-
Indicates whether the EBS volume is deleted on instance termination.
Type: Boolean
- device
-
The device name.
If the volume is attached to a Fargate task, this parameter returns
null.Type: String
- instanceId
-
The ID of the instance.
If the volume is attached to a Fargate task, this parameter returns
null.Type: String
- instanceOwningService
-
The service principal of AWS service that owns the underlying instance to which the volume is attached.
This parameter is returned only for volumes that are attached to Fargate tasks.
Type: String
- requestId
-
The ID of the request.
Type: String
- status
-
The attachment state of the volume.
Type: String
Valid Values:
attaching | attached | detaching | detached | busy - volumeId
-
The ID of the volume.
Type: String
