Unable to view files from azure file share volume mount in ACI container

I am trying to mount an Azure file share volume to an ACI container group and instance.

C# code snippet


.DefineVolume(volumeMountName)
                    .WithExistingReadWriteAzureFileShare(shareName)
                    .WithStorageAccountName(storageAccountName)
                    .WithStorageAccountKey(storageAccountKey)
                    .Attach()
                .DefineContainerInstance(containerGroupName)
                    .WithImage($"{acrServer}/{containerImage}:{Constant.ACIVersion}")                    
                    .WithExternalTcpPort(80)
                    .WithVolumeMountSetting(volumeMountName,"/aci/logs/")
                    .WithCpuCoreCount(1.0)
                    .WithMemorySizeInGB(1.5)
                    .WithEnvironmentVariables(envVars)
                    .Attach()

Above code works fine and it launches the ACI container in Azure.

enter image description here

However, when I try to list the files from within the container , for ex:
Directory.GetFiles("/aci/logs/z-vol/") or Directory.GetFiles("//z-vol//")
I don’t get any results, also when I write to this directory location, the new file doesn’t reflect in Azure file share in the portal.

What I am missing here? I am running ubuntu image. Any help is appreciated. thanks!
