This is because the placement group containing that object likely
needs to scrub (just a light scrub should do). The scrub will compare
the two replicas, notice the replica is missing from the secondary and
trigger recovery/backfill. Can you try scrubbing the placement group
containing the removed object and let us know if it triggers recovery?

[ceph-users] why object can't be recovered when delete one replica

[ljm李嘉敏]

Hi all,

I upload a file through swift API, then delete it in the “current” directory in 
the secondary OSD manually, why the object can’t be recovered?
If I delete it in the primary OSD, the object is deleted directly in the pool 
.rgw.bucket and it can’t be recovered from the secondary OSD.
Do anyone know this behavior?

PS: the rep size is 2.

Thanks & Regards
Li JiaMin
