Adding NFS storage as external volume (Unity)

phguk — Wed, 10 Jan 2024 08:24:34 GMT

Can anyone share experience (or point me to another reference) that describes how to configure Azure Blob storage which has NFS enabled as an external volume to Databricks ?

I've succeeded in adding SMB storage to Databricks but (if I understand properly) the use of NFS disables public network access to the storage.

Thanks in advance

Apologies for the delay & many thanks for responding. Yes I've been able to mount my premium storage + NFS container as an external volume to Databricks.

hi @phguk could you share how you managed to create an external volume referencing to an azure fileshare ?are you using Unity catalog for this ? it was my understanding this is not possible.

Yes I'm using Unity catalog and have defined my storage account as external storage volume to Databricks. Databricks are very clear that really you should limit access using Unity. Direct access to the storage account rather undermines the security implemented by Unity.

I am facing the same issue.

Hi @phguk
Can you able to solve this ? If yes, can you please share how ?

Hi @walter
Is it possible for you to provide a document link or connection detail you add to create this external location connection ?

Thanks in advance.

@phguk - how have you added SMB storage to Databricks ? usingazure.storage.fileshare -> ShareFileClient ? or is there any other way?
