AKS Blob mounting failed, reason given by sercer: No such file or directory

Question

Hello,

I am troubleshooting an issue with NFS pvc in AKS using Azure Blob storage.

I have opened all network connections from the AKS to the blob storage but it still has trouble mounting the volume.

I can see the pv in the containers of the storage account as mentioned over here: mounting ektaccount.blob.core.windows.net:/ektaccount/pvc-465ff843-67b3-472f-8986-9b822cc8a172 failed, reason given by server: No such file or directory

Without any success.

Any next troubleshooting steps?

Hello @Nikos Fotiou

Thank you for your question, I understand that you have an issue with NFS PVC in AKS using Blob storage.

This error message indicates that the server cannot find the specified file or directory. You can try the following steps to resolve the issue:

1. Check if the file or directory exists in the specified location.
2. Check if the file or directory has the correct permissions.
3. Check if the file or directory is accessible from the server.
4. Check if the NFS server is running and accessible.
5. Check if the NFS share is properly configured and mounted.
6. Check if the firewall is blocking the NFS traffic.
7. Check if the network connectivity is stable and reliable.

If for some reason, the mount operation on Pods is failing, you can check at the Node level with the following commands

mkdir /Path

mount -o sec=sys,vers=3,nolock,proto=tcp azstorageblobtest.blob.core.windows.net:/BlobStorageName/Name /Path

for more information please check the sample from this document and try the same: https://learn.microsoft.com/en-us/azure/aks/azure-csi-blob-storage-provision?tabs=mount-nfs%2Csecret#storage-class-using-nfs-protocol

Also please check the full example: Mount Azure Blob containers with NFS in AKS Cluster

if it worked you have to check the path mounted by PVC to the pod.
