We have deployed PVC and MySql DB pod in AKS ..one of devs accidentally restarted the db pod which results into following error.

MountVolume.SetUp failed for volume "pvc-f000d3cf-475d-4664-a977-5af1dbe6acdf" : mount failed: exit status 32 Mounting command: mount Mounting arguments: -t nfs -o vers=3 10.120.18.99:/export/pvc-f000d3cf-475d-4664-a977-5af1dbe6acdf /var/lib/kubelet/pods/f6e8043b-b18c-4a58-ab4e-a4bcdb522776/volumes/kubernetes.io~nfs/pvc-f000d3cf-475d-4664-a977-5af1dbe6acdf Output: mount.nfs: access denied by server while mounting 10.120.18.99:/export/pvc-f000d3cf-475d-4664-a977-5af1dbe6acdf.

Any Help would be much appreciated

    Hello @Sai Teja Reddy Gurujala ,
    Based upon the error message "Output: mount.nfs: access denied by server while mounting 10.120.18.99:/export/pvc-f000d3cf-475d-4664-a977-5af1dbe6acdf."
    It seems the AKS Pod which it is trying to mount the file share from the storage account does not have the right permissions"

    One of the reason might be:- Check if the storage account is firewall enabled.
    If the storage account is behind the Firewall , try to add AKS VNET/Subnet in the Storage Account Networking Firewall

    Also please check your PV , PVC yaml files and validate the NFS version, sometimes these will happen due to NFS version mismatch
