ceph-csi VS aws-efs-csi-driver

So, apparently ceph doesn't provide this feature anymore and, while for rbd this works fine, I'm left a bit confused. Following these examples https://github.com/ceph/ceph-csi/tree/devel/examples/cephfs I thought it would be enough, but not sure anymore.

There’s an official ceph csi plug-in https://github.com/ceph/ceph-csi

In the past I was have problems with GID allocator, something related to this problem.

However, the docs (https://github.com/kubernetes-sigs/aws-efs-csi-driver/blob/master/examples/kubernetes/dynamic_provisioning/README.md) are telling me to create EFS Mount Targets in the EKS subnets. Thats fine.

Fargate storage A Pod running on Fargate automatically mounts an Amazon EFS file system. You can't use dynamic persistent volume provisioning with Fargate nodes, but you can use static provisioning. For more information, see Amazon EFS CSI Driver on GitHub.

I guess something like this might go a long way to solve the problem https://github.com/kubernetes-sigs/aws-efs-csi-driver/pull/640 ? Though I see it isn't merged yet

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:

In each namespace, create a PV/PVC using the same fixed volume path. See "Volume Path in EKS CSI Driver" To make this work however, you MUST pre-create this volume path in your EFS (I usually just have an EC2 instance with it mounted to work on). From the docs above "Note: this feature requires the sub directory to mount precreated on EFS before consuming the volume from"

resource "aws_iam_policy" "eks_efs_csi_driver_policy" { # https://github.com/kubernetes-sigs/aws-efs-csi-driver/blob/master/docs/iam-policy-example.json policy = file("./6.AWSEFSpolicy.json") name = "aws-efs-csi-policy" }
