Dead Ends

Common approaches that don't work:

  1. 70% fail

    Setting partitions to 1 in a script that mistakenly passes 0 (e.g., from a default config) still fails; the fix is to validate input before the API call.

  2. 90% fail

    Using a negative value from a bug in partition calculation code (e.g., integer overflow) will still be rejected; the code must be fixed.
