Thanks! looks like documentation is not up to date. Asking my question again since it's very important to know how to find out if self healing worked.
How will I know if self heal worked or not. What's the best way to tell? I see there are 2 find commands and it looks in some cases running one may not be sufficient. So how can we make sure that self heal worked. Currently I am testing with one file so it's easy to verify but with millions of files it may not be possible.
