Hello Ben,

I’m facing with the same issue - #10295 and I remove the object directly from that rados successfully. But is very important map all object before do that. I recommend you take a look to the links bellow to understand more about the objects name:

Subject: Re: [ceph-users] Shadow files

Anyone got any info on this?

Is it safe to delete shadow files?

It depends. Shadow files are badly named objects that represent part of the objects data. They are only safe to remove if you know that the corresponding objects no longer exist.

We have a large number of shadow files in our cluster that aren't
being deleted automatically as data is deleted.

Is it safe to delete these files?
Is there something we need to be aware of when deleting them?
Is there a script that we can run that will delete these safely?

Is there something wrong with our cluster that it isn't deleting these
files when it should be?

We are using civetweb with radosgw, with tengine ssl proxy infront of
it

Any advice please
Thanks
