Hi cephers,

In ceph version 10.2.11, we use three replication to protect our
production data.

Today I find some inconsistent pgs, I try to repair , but the pg still
shows inconsistent.

I go deep into the problem and find that, all three replicated data
has the same data digest and omap digest both in object_info_t and
scrub map object , but data digest in object_info_t is different from
the data digest in scrub map object. And the log displays that ":
failed to pick suitable auth object" and go out without repare the
data digest in object_info_t .

In hammer , when this situation appears, the code would repair the
data digest in object_info_t,
but in jewel and Lumious, nothing is done.

So i want to check , is it need to repair the objects when encoutering
this situation ? Does the jewel and Lumious missed this situation?

If we want to repair,, i will open a tracker and do a pull request.

Cheers,
brandy
