First start with some added information.
- Distribution
- kernel
- raidtools used
- kernel raid patch used
- raidtab

0.4x raid instead of 0.90 (preferred) It might be worth starting at:

The Introduction covers the issue fairly well, just ignore that
overly-optimistic phrase "...when the 2.4 kernel comes out (hopefully
around christmas 1999)..." :)
