Data Share no support for Azure Blob Storage with restrcited network (for NFSv3)?

Tilo 26

Hi,

seems we can't map the data share to a target which is a NFSv3 enabled Azure Blob Storage.
Please clarify.

This page doesn't mention anything https://github.com/MicrosoftDocs/azure-docs/blob/main/articles/data-share/supported-data-stores.md about such a restriction.

Then I try to change my Storage account with NFSv3 to Public I get this warning: NFS v3 is enabled for this storage account. Setting network access to 'all networks' will cause network access using this protocol to fail.

Thanks, Tilo

Hi Tilo ,

Azure Data Share currently does not support NFSv3 enabled Azure Blob Storage as a target. This limitation is the reason you cannot map the data share to this type of storage account.

When you enable NFSv3 on a storage account, it requires specific network configurations. Setting network access to 'all networks' will disable NFSv3 protocol access because NFSv3 relies on secure network configurations, typically within a virtual network. This is why you receive the warning when attempting to change the network access settings.

If you need to use NFSv3, ensure that your storage account is within a virtual network and that network security settings are properly configured. If you need broader network access, you might need to reconsider using NFSv3 for that particular storage account.

I hope this information helps! Let us know if you have any further questions. We will be glad to assist you further.

where does MS document such limitation of Azure Data Share?

Hi Tilo ,

The specific limitation regarding Azure Data Share not supporting NFSv3-enabled Azure Blob Storage with restricted network access isn't explicitly documented in the Azure Data Share documentation. However, the known issues and limitations of NFSv3 support in Azure Blob Storage are detailed in the Azure Storage documentation

For more information:

On the limitations of NFSv3 in Azure Blob Storage, you can refer to the

Known issues with NFS 3.0 in Azure Blob Storage
https://learn.microsoft.com/en-us/azure/data-share/

If you have any other questions or are still running into more issues, let me know in the "comments" and I would be happy to help you.

Hi, not sure if you work for MS or not, but if you please push for get such imitation of Data Share documented by MS. Thanks.

ALternative might be to use **BlobFuse **instread of NFSv3 enabled Azure Blob Storage.

I succesfully tested a BlobFuse2 connection to an Azure Blob Storage which was used in a Data Share. (from a AKS container Pod)

@ Tilo , I understand your concern about the MS documentation,

It's great to hear that you successfully tested a BlobFuse2 connection! BlobFuse is indeed a good alternative to NFSv3 for accessing Azure Blob Storage, especially when dealing with network restrictions.

Bases on your specific issue, I Suggest you might want to refer to the below documentation:

Azure Data Share Overview: This page provides a general overview of Azure Data Share, including its capabilities and supported scenarios.

Supported Data Stores: This section lists the data stores that are compatible with Azure Data Share.

NFS 3.0 Protocol Support for Azure Blob Storage: This page provides detailed information on the requirements and limitations of using NFSv3 with Azure Blob Storage.

If you have any other questions or are still running into more issues, let me know in the "comments" and I would be happy to help you.
