Not able to mount azure blob storage with azure data bricks

Question

I am using below code

#Define parameters
storage_account_name = "rupeshblob001"  # e.g., "mystorageaccount"
container_name = "testcontainer"  # e.g., "mycontainer"
mount_point = "/mnt/mymountpoint"  # e.g., "/mnt/mydata"
#If using an access key
storage_account_key ="dxtmnXpJyY/A5CrERQ0Qqj/otBPh0GBBRqGYVbWhSHamxq4uLHtF1Fh3ZrKNU5RGtaItAqCPFx4w+AStIJrj3Q=="
#Mount the storage
  dbutils.fs.mount(
  source = "wasbs://{container_name}@{storage_account_name}.blob.core.windows.net",
  mount_point = "/mnt/iotdata",
  extra_configs = {"fs.azure.account.key.{storage_account_name}.blob.core.windows.net":dbutils.secrets.get(scope = "geekcoders-secret", key = "sroragekey")})

I am getting below error when run above code from azure databricks note book. I need this help urgently. any help will be appreciated. 
ExecutionError: An error occurred while calling o420.mount. : java.io.FileNotFoundException: Operation failed: "The specified filesystem does not exist.", 404, HEAD,

Hi Rupesh Kumar Mishra ,
Welcome to Microsoft Q&A, Thank you for posting your query.

Azure Databricks is unable to locate the Blob Storage container you're trying to mount.

Below are the steps to mount:

1. Check Storage Account and Container Names are correct.
2. Container should exist in storage account.
3. In your code, you're mixing an access key with Databricks secrets. Instead of using dbutils.secrets.get(). You're already providing the storage_account_key directly, so you don't need to use the secrets function unless your key is stored in the Databricks secret scope.
4. storage_account_name = "rupeshblob001"

container_name = "testcontainer"

mount_point = "/mnt/iotdata"

Use access key directly

storage_account_key = "dxtmnXpJyY/A5CrERQ0Qqj/otBPh0GBBRqGYVbWhSHamxq4uLHtF1Fh3ZrKNU5RGtaItAqCPFx4w+AStIJrj3Q=="

Mount the storage

dbutils.fs.mount(

source = f"wasbs://{container_name}@{storage_account_name}.blob.core.windows.net",

mount_point = mount_point,

extra_configs = {f"fs.azure.account.key.{storage_account_name}.blob.core.windows.net": storage_account_key}

)

5. If you've regenerated the storage account keys recently, you may be using an outdated key.

Please refer the below Microsoft Documentation.
