Storage for Azure ML Workspace

Hello:

When I create Azure ML Workspace, why I cannot use existing storage, why I have to create new one?

Any clarification will help me to educate.

Thanks

You may use an existing storage account for AZ ML Workspace. Let's know the challenge while using like that so that we will understand the issue better and to support on that well

Hello Manu:

Thanks for your reply, when i try to create new Azure ML Service, It didn't allowed me to select existing storage account - ADLS Gen2.

So i endup creating new at the time of creating (AML01).

I try to create another one (AML02) and it did allowed me to select storage account for the AML01 workspace but not the ADLS Gen2.

Thanks

Hello Manu:

I came across MS Link and it make sense.

https://docs.microsoft.com/en-us/cli/azure/ml/datastore?view=azure-cli-latest

When you create a workspace, an Azure Storage account is automatically created as an associated resource. A blob container is created in this account, and its connection information is stored as a datastore named 'workspaceblobstore'. This serves as the workspace's default datastore, and the blob container is used to store your workspace artifacts and machine learning job logs and outputs.

So this is what I experienced as mention above.

Thanks

Looks like an IAM assignment needed for the storage account.

Check it after granting the service principal with Storage Blob Data Reader access.
