Constructor Details #initialize(id, options = {}) ⇒ Object #initialize(options = {}) ⇒ Object Instance Attribute Details #availability_zone ⇒ String

The Availability Zone for the volume.

#create_time ⇒ Time

The time stamp when volume creation was initiated.

#encrypted ⇒ Boolean

Indicates whether the volume is encrypted.

#fast_restored ⇒ Boolean

Indicates whether the volume was created using fast snapshot restore.

#iops ⇒ Integer

The number of I/O operations per second (IOPS) that the volume supports. For Provisioned IOPS SSD volumes, this represents the number of IOPS that are provisioned for the volume. For General Purpose SSD volumes, this represents the baseline performance of the volume and the rate at which the volume accumulates I/O credits for bursting. For more information, see Amazon EBS volume types in the Amazon Elastic Compute Cloud User Guide.

Constraints: Range is 100-16,000 IOPS for gp2 volumes and 100 to 64,000 IOPS for io1 and io2 volumes, in most Regions. The maximum IOPS for io1 and io2 of 64,000 is guaranteed only on Nitro-based instances. Other instance families guarantee performance up to 32,000 IOPS.

Condition: This parameter is required for requests to create io1 and io2 volumes; it is not used in requests to create gp2, st1, sc1, or standard volumes.

#kms_key_id ⇒ String

The Amazon Resource Name (ARN) of the AWS Key Management Service (AWS KMS) customer master key (CMK) that was used to protect the volume encryption key for the volume.

#multi_attach_enabled ⇒ Boolean

Indicates whether Amazon EBS Multi-Attach is enabled.

#outpost_arn ⇒ String

The Amazon Resource Name (ARN) of the Outpost.

#size ⇒ Integer

The size of the volume, in GiBs.

#snapshot_id ⇒ String

The snapshot from which the volume was created, if applicable.

#state ⇒ String

The volume state.

Possible values:

creating
available
in-use
deleting
deleted
error

#tags ⇒ Array<Types::Tag>

Any tags assigned to the volume.

#volume_type ⇒ String

The volume type. This can be gp2 for General Purpose SSD, io1 or io2 for Provisioned IOPS SSD, st1 for Throughput Optimized HDD, sc1 for Cold HDD, or standard for Magnetic volumes.

Possible values:

standard
io1
io2
gp2
sc1
st1

Instance Method Details #attach_to_instance(options = {}) ⇒ Types::VolumeAttachment

Attaches an EBS volume to a running or stopped instance and exposes it to the instance with the specified device name.

Encrypted EBS volumes must be attached to instances that support Amazon EBS encryption. For more information, see Amazon EBS Encryption in the Amazon Elastic Compute Cloud User Guide.

After you attach an EBS volume, you must make it available. For more information, see Making an EBS volume available for use.

If a volume has an AWS Marketplace product code:

The volume can be attached only to a stopped instance.
AWS Marketplace product codes are copied from the volume to the instance.
You must be subscribed to the product.
The instance type and operating system of the instance must support the product. For example, you can't detach a volume from a Windows instance and attach it to a Linux instance.

For more information, see Attaching Amazon EBS volumes in the Amazon Elastic Compute Cloud User Guide.

#create_snapshot(options = {}) ⇒ Snapshot #create_tags(options = {}) ⇒ Array<Tag> #delete(options = {}) ⇒ Struct

Deletes the specified EBS volume. The volume must be in the available state (not attached to an instance).

The volume can remain in the deleting state for several minutes.

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

#delete_tags(options = {}) ⇒ Array<Tag> #describe_attribute(options = {}) ⇒ Types::DescribeVolumeAttributeResult

Describes the specified attribute of the specified volume. You can specify only one attribute at a time.

For more information about EBS volumes, see Amazon EBS Volumes in the Amazon Elastic Compute Cloud User Guide.

#describe_status(options = {}) ⇒ Types::DescribeVolumeStatusResult

Describes the status of the specified volumes. Volume status provides the result of the checks performed on your volumes to determine events that can impair the performance of your volumes. The performance of a volume can be affected if an issue occurs on the volume's underlying host. If the volume's underlying host experiences a power outage or system issue, after the system is restored, there could be data inconsistencies on the volume. Volume events notify you if this occurs. Volume actions notify you if any action needs to be taken in response to the event.

The DescribeVolumeStatus operation provides the following information about the specified volumes:

Status: Reflects the current status of the volume. The possible values are ok, impaired , warning, or insufficient-data. If all checks pass, the overall status of the volume is ok. If the check fails, the overall status is impaired. If the status is insufficient-data, then the checks may still be taking place on your volume at the time. We recommend that you retry the request. For more information about volume status, see Monitoring the status of your volumes in the Amazon Elastic Compute Cloud User Guide.

Events: Reflect the cause of a volume status and may require you to take action. For example, if your volume returns an impaired status, then the volume event might be potential-data-inconsistency. This means that your volume has been affected by an issue with the underlying host, has all I/O operations disabled, and may have inconsistent data.

Actions: Reflect the actions you may have to take in response to an event. For example, if the status of the volume is impaired and the volume event shows potential-data-inconsistency, then the action shows enable-volume-io. This means that you may want to enable the I/O operations for the volume by calling the EnableVolumeIO action and then check the volume for data consistency.

Volume status is based on the volume status checks, and does not reflect the volume state. Therefore, volume status does not indicate volumes in the error state (for example, when a volume is incapable of accepting I/O.)

#detach_from_instance(options = {}) ⇒ Types::VolumeAttachment

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.

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

#enable_io(options = {}) ⇒ Struct

Enables I/O operations for a volume that had I/O operations disabled because the data on the volume was potentially inconsistent.

#modify_attribute(options = {}) ⇒ Struct

Modifies a volume attribute.

By default, all I/O operations for the volume are suspended when the data on the volume is determined to be potentially inconsistent, to prevent undetectable, latent data corruption. The I/O access to the volume can be resumed by first enabling I/O access and then checking the data consistency on your volume.

You can change the default behavior to resume I/O operations. We recommend that you change this only for boot volumes or for volumes that are stateless or disposable.

#snapshots(options = {}) ⇒ Collection<Snapshot>
