问题
I am currently trying to create an EFS for use within an EKS cluster. I've followed all the instructions, and everything seems to be working for the most part. However, when trying to apply the multiple_pods example deployment from here, the pods cannot succesfully mount the file system. The PV and PVC are both bound and look good, however the pods do not start and yield the following error message:
Warning FailedMount 116s (x10 over 6m7s) kubelet, ip-192-168-42-94.eu-central-1.compute.internal MountVolume.SetUp failed for volume "efs-pv" : kubernetes.io/csi: mounter.SetupAt failed: rpc error: code = Internal desc = Could not mount "fs-080b8b50:/" at "/var/lib/kubelet/pods/3f7c898d-c3de-42e7-84e5-bf3b56e691ea/volumes/kubernetes.io~csi/efs-pv/mount": mount failed: exit status 1

To me the error looks like it may not be related to my configuration, however as I expect AWS's example deployments to work, I doubt that. I'm neither familiar with python's ConfigParser nor with EFS, so I can only guess what that error really means. Thanks alot for any help!

Faced a similar problem.
Fixed by update efs-csi-node daemonset from amazon/aws-efs-csi-driver:v0.3.0 image to amazon/aws-efs-csi-driver:latest

This bug here seems to have already been fixed. So now it works fine if you install it in the following way.
kubectl apply -k "github.com/kubernetes-sigs/aws-efs-csi-driver/deploy/kubernetes/overlays/stable?ref=master"
Settings that are incompatible with v0.3.0 images have been reverted by the following PR It seems. https://github.com/kubernetes-sigs/aws-efs-csi-driver/pull/196
