![]() The output should include the ephemeral disks, which typically have device names starting with “nvme” or “xvd”. This command lists all block devices that start with “sd”, “xvd”, or “nvme” and shows the device name, size, type, and mount point (if any). Please refer to this code as experimental only since we cannot currently guarantee its validity lsblk -d -o NAME,SIZE,TYPE,MOUNTPOINT | grep '^sd\|^xvd\|^nvme' ⚠ This code is experimental content and was generated by AI. Here is an example command to list the ephemeral disks on an Amazon EC2 instance: You can use the -d option to show only the disk devices and the -o option to specify the output format. The lsblk command lists all block devices, including ephemeral disks, attached to the instance. To list the ephemeral disks on an Amazon EC2 AMI, you can use the lsblk command in Linux. This can be useful for ensuring that the AMI is configured correctly and that any data stored on the ephemeral disks is not lost during the launch of the instance. When creating an Amazon EC2 AMI, you may want to list the ephemeral disks that are available for the instance type. ![]() Listing Ephemeral Disks on an Amazon EC2 AMI The device names for the ephemeral disks typically start with “ephemeral” and are followed by a number, depending on the number of ephemeral disks available for the instance type. ![]() The block device mappings for the ephemeral disks are specified in the instance launch configuration. When an EC2 instance is launched, the ephemeral disks are created and attached to the instance as block devices. For example, an m5.large instance type has one 75 GB NVMe SSD ephemeral disk, while an r5d.8xlarge instance type has two 600 GB NVMe SSD ephemeral disks. The number and size of ephemeral disks that are available depend on the instance type. How Ephemeral Disks WorkĮphemeral disks are created from a pool of storage devices that are available on the host machine where the EC2 instance is running. Ephemeral disks are also useful for high-performance computing workloads, as they offer high I/O performance and low latency compared to Elastic Block Store (EBS) volumes. The number and size of ephemeral disks depend on the instance type and the region in which the instance is launched.Įphemeral disks are useful for storing temporary data that does not need to be saved permanently, such as cache files, temporary logs, and scratch space for computational workloads. Ephemeral disks are not persistent, which means that any data stored on them will be lost when the instance is terminated or stopped. What is an Ephemeral Disk?Īn ephemeral disk is a temporary storage device that is created and attached to an EC2 instance during the instance launch. In this blog post, we will discuss what ephemeral disks are, how they work, and how to list them on an Amazon EC2 AMI. ![]() Ephemeral disks are temporary storage devices that are created and attached to an EC2 instance during the instance launch. | Miscellaneous ⚠ content generated by AI for experimental purposes onlyĪs a data scientist or software engineer working with Amazon Web Services (AWS), you might have come across the term “ephemeral disk” while creating an Amazon Machine Image (AMI) for your EC2 instances.
