Problem adding rasters to mosaic dataset

[Syvertson]

I have just created a mosaic dataset in a SQL Server Database.  When I attempt to add rasters to the Mosaic Dataset it fails.  The rasters are 4 band aerial imagery.  These are the messages for the process:

For reference, I have two federated servers.  One is the hosting server and has portal on it, and the second is the Raster Analysis Server.  See below:

Thanks in advance for any assistance you can provide.

1. Are your raster files stored on a file share?  Is the file share registered as a datastore on your Image/RA server?

2. Is the MDS feeding an image service?  If yes, stop the services and run your process again.

3.  Not knowing your infrastructure capabilities, limitations and constraints, Why host the MDS in RDBMS?  A FGDB does well in these workflows.

1.  The ratsers are stored in a network drive that is referenced folder in the ArcGIS Datastore.

2.  Not feeding an image service yet.  I am just created it and started to load ratsers into it.

3.  I only used the SQL Server because almost everything I do is in SQL Server.  Only use FGDB for personal projects that will not be shared enterprise wide.
