Thank you for the information.

I have removed --assume-clean in the script and executed the stress
after that raid5 completed resync.

The files are all consistent in the rest tests.

I am now wondering, what's different between the implementation of
raid5 algorithm and of raid6 algorithm?

Would you please suggest some hints in the implementation?

Thank you,
Peng.
