You'll need to tell us exactly what error messages you're seeing, what the output of ceph -s is, and the output of pg query for the relevant PGs.
There's not a lot of documentation because much of this tooling is new, it's changing quickly, and most people don't have the kinds of problems that turn out to be unrepairable. We should do better about that, though.

I am asking the same questions too, it seems strange to me that in a
fault tolerant clustered file storage like Ceph there is no
documentation about this.
I know that I am pedantic but please note that saying "to be sure use
three copies" is not enough because I am not sure what Ceph really does
when three copies are not matching.
