I am not able to get reliable results from shell/lvconvert-repair-raid.sh
either. For 6.6.0 kernel, the test fails. On 6.8-rc1 kernel, the test fails
sometimes.

Could you please share more information about your test setup?
Specifically:
1. Which tree/branch/tag are you testing?
2. What's the .config used in the tests?
3. How do you run the test suite? One test at a time, or all of them
together?
4. How do you handle "test passes sometimes" cases?

Thanks,
Song
