EFS does not Automaticall mount on Reboot

Hi.

AWS EFS does not automatically mounts in a EC2 Intance. But there are diferent ways to automatically mount the EFS.

Here in the link number [1], you can select between different options. And also It will depend on the services that you are using.

1. Probably if your are using Auto Scaling group, you can mount it using the user data in the auto scaling group.
2. If you are using a single EC2 instance, you can use either the fstab configuration in the [1] link or you can mount it using a crontab in a linux environment.
3. And also you can configure an automount in the EC2 Launch Instance Wizard.

All this information it's in the same link.

Hope this can help you.

Best regards!
