New users were added to Active Directory to access the Data Mover. As time goes by and more users are added to and removed from Active Directory, new users access the Data Mover using Windows SIDs that must be mapped to UIDs and GIDs. The usermapper database automatically creates new UIDs and GIDs from these SIDs. As a result, the usermapper database can become very large. The self healing feature of the Database may not be enough for the nasdb backup to complete and require some extra manual help to compact the nasdb for it to complete.
New users were added to Active Directory to access the Data mover, and therefore the usermapper become very large and could not be backup without manual help to compact the usemapper database.
Here are the steps. Read and understand the steps. If you are not sure, do not run these steps and ask for help from a senior TSE.
