Is a scrub error (read_error) on a primary osd safe to repair?

Hi all,

I tried to dig in the mailinglist archives but couldn't find a clear answer to the following situation:

Ceph encountered a scrub error resulting in HEALTH_ERR
Two PG's are active+clean+inconsistent. When investigating the PG i see a "read_error" on the primary OSD. Both PG's  are replicated PG's with 3 copies.

I'm on Luminous 12.2.5 on this installation, is it safe to just run "ceph pg repair" on those PG's or will it then overwrite the two good copies with the bad one from the primary?
If the latter is true, what is the correct way to resolve this?

Kind regards,
Caspar Smit
