Type of disk attached to an instance

Question

Hello. Is there an easy way to find out if the disk attached to an instance is gp2, gp3 or io1? I'd like to know how to do this both from the console and once I'm connected to the instance. The console simply shows:
```EBS-optimized				False
Root device type			ebs
Root device				/dev/sda1
Block devices				/dev/sda1
					/dev/sdb
Elastic Graphics ID			-
Elastic Inference accelerator ID	-
Capacity Reservation			-
Capacity Reservation Settings		Open
Outpost Arn				-```

Accepted Answer

Here is a command you can run to show this information. Replace `$INSTANCE_ID` below with your instance ID.

```
aws ec2 describe-volumes --filters Name=attachment.instance-id,Values=$INSTANCE_ID --query '[Volumes[*].VolumeId,Volumes[*].Attachments[0].InstanceId,Volumes[*].Attachments[0].Device,Volumes[*].VolumeType]' --output text
```

Each volume attached to the instance will be in a separate column. The row values are the volume ID, instance ID, device attachment, and volume type. For example:

```
vol-xxxxxxxxxxx   vol-zzzzzzzzz
i-yyyyyyyyy     i-yyyyyyyyy
/dev/xvda       /dev/sdf
gp2     gp3
```

Answer

Hi, good question. You can do this on the new AWS Management console by viewing volumes, where this will list information such as size, volume type, whether the volume is encrypted, which KMS key was used to encrypt the volume, and the specific instance to which it is attached.

Via CLI: describe-volumes

Answer

To look it up by volume device name (/dev/nvme1n1 in my example), use the following command:
```
lsblk -P -o SERIAL /dev/nvme1n1 |cut -d "\"" -f 2 | sed "s/vol/vol-/" | xargs aws ec2 describe-volumes --volume-ids --query "Volumes[*].VolumeType" --output text
```

The command will return the volume type:

```
gp3
```
