[SOLVED] Connection reset by peer : AWS EFS

Issue

I am trying to setup EFS and access it using EC2 instances in different availability zones. I have created a separate security group for EFS, which allows traffic for the security group attached to EC2 instances. Installed amazon-efs-utils utility on the EC2 instances also. But when trying to execute the following command: sudo mount -t efs -o tls EFS-ID:/ efs

I am getting the following error:

mount.nfs4: Connection reset by peer

I have tried it several times, but it did not work. What am I missing here ? Could anyone please let me know.

Thanks

Solution

This was becase DNS hostnames was not enabled on the custom VPC which I had created. It worked after enabling it. Please find more information here: https://docs.aws.amazon.com/efs/latest/ug/mounting-fs-mount-cmd-dns-name.html

thx
