在EKS集群中挂载EFS:示例部署失败 [英] Mounting EFS in EKS cluster: example deployment fails

问题描述

我当前正在尝试创建一个EFS以在EKS集群中使用.我已经按照所有说明进行了操作，并且大多数情况下似乎一切正常.但是，当尝试从此处应用multi_pods示例部署时， Pod无法成功挂载文件系统. PV和PVC都已绑定并且看起来不错，但是吊舱无法启动并产生以下错误消息:

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

在我看来，该错误似乎与我的配置不相关，但是由于我希望AWS的示例部署能够正常工作，我对此表示怀疑.我既不熟悉python的ConfigParser，也不熟悉EFS，所以我只能猜测该错误的真正含义.非常感谢您的帮助！

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!

遇到了类似的问题.

已通过将efs-csi-node守护程序集从amazon/aws-efs-csi-driver:v0.3.0映像更新为amazon/aws-efs-csi-driver:latest

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