All shards of PG missing object and inconsistent

Hi all,

 

I have recently performed a few tasks, namely purging several buckets from our RGWs and added additional hosts into Ceph causing some data movement for a rebalance. As this is now almost completed, I kicked off some deep scrubs and one PG is now returning the following information:

The object I recognise by name as belonging to a bucket purged earlier in the day, and is meant to be deleted. What would be the best means to resolve this inconsistency when the object is supposed to be absent?

 

Kind Regards,

 

Thomas
