Question

I am following this tutorial to mount efs on AWS EC2 instance but when Iam executing the mount command

sudo mount -t nfs4 -o vers=4.1 $(curl -s http://169.254.1         


        

Answer 1

A different answer here, as I faced a very similar error and none of the answers fit.

I was trying to mount a NFS like below (in my case EKS was doing that on my behalf, but I tested the very same command manually in the worker node with the same result):

[root@host ~]# mount -t nfs fs-abc1234.efs.us-east-1.amazonaws.com:/persistentvolumes /mnt/test

Output was: mount.nfs: Connection timed out

When I simply tried the same command, but using / as the path:

[root@host ~]# mount -t nfs fs-abc1234.efs.us-east-1.amazonaws.com:/ /mnt/test

It worked like a charm!

I really do not understand how a possible wrong or missing path can lead to a time out kind of error, but that was the only thing that could fix the problem for me, all the network configuration remained the same.

As I was using EKS/Kubernetes, I dedcided to mount /, which works, and then use subPath to change the volume mounting point in the container configuration.
