S3 Data access through unity

[adrjuju]

Hey All I have the following issue : 

I've connected a s3 bucket through unity catalog as an external source. I perfectly see the files of my s3 bucket when i scroll through the catalog using the user interface. 

However when I try to connect through a notebook using this code : 

files = dbutils.fs.ls(LUMA_PATH)

I got the following error 

ExecutionError: An error occurred while calling o411.ls. : com.databricks.backend.daemon.data.common.InvalidMountException: Error while using path /Volumes/privatepath for creating file system within mount at '/Volumes/privatepath.

What is weird to me is that this exact command worked for some time after the creation of the cluster but it's not working anymore. 

Any ideas ?

What is the value of LUMA_PATH? is it /Volumes or s3://

Hey Chandra thank you for your answer. 

The path is a volume path indeed, : /Volumes/my_path_in_volume

This needs backend intervention to check what is blocking access to cloud files from the cluster. Could be Private Link.
