ec2_modify_volume: You can modify several parameters of an existing EBS volume, including volume size, volume type, and IOPS capacity

Description

You can modify several parameters of an existing EBS volume, including volume size, volume type, and IOPS capacity. If your EBS volume is attached to a current-generation EC2 instance type, you might be able to apply these changes without stopping the instance or detaching the volume from it. For more information about modifying EBS volumes, see Amazon EBS Elastic Volumes in the Amazon EBS User Guide.

See https://www.paws-r-sdk.com/docs/ec2_modify_volume/ for full documentation.

Usage

ec2_modify_volume(
  DryRun = NULL,
  VolumeId,
  Size = NULL,
  VolumeType = NULL,
  Iops = NULL,
  Throughput = NULL,
  MultiAttachEnabled = NULL
)

Arguments

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 is UnauthorizedOperation.

VolumeId

[required] The ID of the volume.

Size

The target size of the volume, in GiB. The target volume size must be greater than or equal to the existing size of the volume.

The following are the supported volumes sizes for each volume type:

gp2 and gp3: 1 - 16,384 GiB
io1: 4 - 16,384 GiB
io2: 4 - 65,536 GiB
st1 and sc1: 125 - 16,384 GiB
standard: 1 - 1024 GiB

Default: The existing size is retained.

VolumeType

The target EBS volume type of the volume. For more information, see Amazon EBS volume types in the Amazon EBS User Guide.

Default: The existing type is retained.

Iops

The target IOPS rate of the volume. This parameter is valid only for gp3, io1, and io2 volumes.

The following are the supported values for each volume type:

gp3: 3,000 - 16,000 IOPS
io1: 100 - 64,000 IOPS
io2: 100 - 256,000 IOPS

For io2 volumes, you can achieve up to 256,000 IOPS on instances built on the Nitro System. On other instances, you can achieve performance up to 32,000 IOPS.

Default: The existing value is retained if you keep the same volume type. If you change the volume type to io1, io2, or gp3, the default is 3,000.

Throughput

The target throughput of the volume, in MiB/s. This parameter is valid only for gp3 volumes. The maximum value is 1,000.

Default: The existing value is retained if the source and target volume type is gp3. Otherwise, the default value is 125.

Valid Range: Minimum value of 125. Maximum value of 1000.

MultiAttachEnabled

Specifies whether to enable Amazon EBS Multi-Attach. If you enable Multi-Attach, you can attach the volume to up to 16 Nitro-based instances in the same Availability Zone. This parameter is supported with io1 and io2 volumes only. For more information, see Amazon EBS Multi-Attach in the Amazon EBS User Guide.
