Unable to identify ephemeral storage on EC2 t2.small instance running on Linux

Question

I am trying to create swap memory on an EC2 instance as RAM utilization is quite high.

As per recommendations to do it on ephemeral storage, I am trying to find out which mount point is ephemeral storage?

This is the fstab entry on my instance:

Now I need to know which one is ephemeral storage so that I can use it for swap. If any of these is not ephemeral then how can I get it?

Answer 1

You are using a t2.small instance type.

The T2 instance family does not have an Instance Store (also known as Ephemeral Storage ).

To discover which instance types have Instance Store, see: Amazon EC2 Instance Types

On that page, you will notice that the T2 instances say EBS-Only in the Storage column. If you wish to have an Instance Store, select a different instance type that includes an Instance Store. Alternatively, just use a normal Amazon EBS volume for swap space, since the main reason for using a T2 instance is for cost savings.
