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

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?
Yes, you should call pg repair. Also It's better to upgrade to 12.2.12.
