The desired size specified is bigger than the total size of the source database.

How to fix

1. Check your options file - locate the desiredSize value
2. Verify source database size - confirm the actual size of your source database
3. Reduce the desired size - set it to a value smaller than the source database
4. Consider percentage-based sizing - use percentages for more reliable results

Common Issues

Overestimated size: "desiredSize": "10GB" when source database is only 2GB

Wrong units: "desiredSize": "500MB" when you meant "500KB"

Percentage miscalculation: Assuming database is larger than it actually is

Sizing options

Absolute size: "desiredSize": "1GB" (must be smaller than source)

Percentage-based: "desiredSize": "50%" 

Supported units: B, KB, MB, GB, TB

Example

{
  "desiredSize": "25%"
}
