Errors: 28

 

Hi fellows,

 

I aggregate a dataset from a 3 million row table from a MySQL database, successfully in Query Editor; but once I apply and closed; Power BI destktop returns the below error during Apply Query Changes.

 

This is the error message:

Failed to save modifications to the server. Error returned: 'OLE DB or ODBC error: [DataSource.Error] MySQL: Error writing file '/tmp/MYefEeg0' (Errcode: 28).
'.

 

I cannot import 3 million rows as-id; so aggregated but it fails. Any idea...?

    Hi umutgulac,

    Based on my search, you can use perror command to check that Errcode 28 means “No space left on device”. In your scenario, the error indicates that you don’t have enough space to create temp files needed by big MySQL requests.

    To exclude this error, change MySQL config so that it uses a different temp folder on a different partition. For more details, please review this similar blog.

    Thanks,
    Lydia Zhang

      I followed another workaround; so I could not follow up this reply; but thanks for the answer.
