This is the same security group & subnet & VPC is used for the same EC2 instance & EFS volume ::::::

[srinivle]

Kindly check and help me out !!!

[srinivle]

Also, by the way, how can I identify my efs volume in ec2 instance when it is mounted or do a command of lsblk ???

[srinivle]

It worked after thorough checking. Simply executing the command from "Amazon EC2 mount instructions (from local VPC)" from "AWS EFS Console after creation of EFS volume", it will not work. We need to follow the below steps one after another and then only it will work. This is especially for Ubuntu machine !!!
