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.
