Repair does the equivalent of a deep-scrub to find problems. This mostly is
reading object data/omap/xattr to create checksums and compares them across all
copies. When a discrepancy is identified an arbitrary copy which did not have
I/O errors is selected and used to re-write the other replicas.

the steps it takes? I unfortunately need to use it for an inconsistent pg.
