Notebook - mount a lakehouse fails

I'm trying to mount a lakehouse from another workspace to my Notebook by using this code:

 

notebookutils.fs.mount( 
 "abfss://<workspace_id>@msit-onelake.dfs.fabric.microsoft.com/<lakehouse_id>", 
 "/test"
)

 

NotebookUtils (former MSSparkUtils) for Fabric - Microsoft Fabric | Microsoft Learn

 

(Yes, I am replacing the <workspace_id> and <lakehouse_id> with the GUID's of my workspace and lakehouse)

 

I get an error: 

Py4JJavaError: An error occurred while calling z:notebookutils.fs.mount. : java.util.concurrent.TimeoutException: Futures timed out after [30 seconds]

    Hi frithjof_v ,

     

    I failed at first with this code because the default timeout may not be enough, after increasing the timeout I succeeded:

    notebookutils.fs.mount (
    “abfss://<workspace_id>@msit-onelake.dfs.fabric.microsoft.com/<lakehouse_id>”,
    “/test”.
    {“timeout”: 600} 
)

     

    If you have any other questions please feel free to contact me.

    Hi frithjof_v ,

     

    Use this command to mount lakehouse to the current notebook.

    mssparkutils.fs.mount(“abfss://<workspace_id>@onelake.dfs.fabric.microsoft.com/<lakehouse_id>”, “/lakehouse/test”) #mountPoint such as '/lakehouse/default'

     

    The successful mount is shown below:

     

    You can also make sure that the mount is successful by executing this command below to list all the mount points.

    mssparkutils.fs.mounts()

     

    If you have any other questions please feel free to contact me.
