Attaching EBS volume to EC2 instance

  • Create EC2 instance
  • Create EBS volume and attach it to EC2 instance
  • Ssh into EC2 instance. eg: ssh -i ~/.ssh/id_rsa ubuntu@public-dns-address
  • Format EBS volume: sudo mkfs -t ext4 /dev/sdf
  • Add a line to the /etc/fstab file on EC2 instance: /dev/sdf /vol ext4 defaults,noatime 1 1
  • sudo mkdir /vol to create vol directory.
  • sudo mount /dev/sdf to mount the EBS volume.

It's good to add nobootwait to EBS volumes in fstab to make sure it doesn't hold up your instance in the boot process if it is detached in the future.
