Problem

You have blob storage associated with a storage account mounted, but are unable to access it after access keys are rotated.

Cause

There are multiple mount points using the same storage account.

Remounting some, but not all, of the mount points with new access keys results in access issues.

Solution

  1. Use dbutils.fs.mounts() to check all mount points. Review the dbutils.fs.mounts() documentation for usage details.
  2. Use dbutils.fs.unmount() to unmount all storage accounts. Review the dbutils.fs.unmount() documentation for usage details.
  3. Restart the cluster.
  4. Remount the storage account with new keys. Review the Azure Data Lake Storage Gen2 and Blob Storage documentation for usage details.
