yes the pool on the testcluster contains a lot of objects

I created a new pool, put the object (this time only 100K, just to test
it) and run a deep-scrub -> error

# dd if=/dev/urandom of=test_obj bs=1K count=100

# rados -p nameplosion put c76c7ac2014adb9f0f0837ac1e85fd1e241af225908b6a0c3d3a44d6b866e732_00400000 test_obj

# ceph osd map nameplosion c76c7ac2014adb9f0f0837ac1e85fd1e241af225908b6a0c3d3a44d6b866e732_00400000
osdmap e2016317 pool 'nameplosion' (7) object 'c76c7ac2014adb9f0f0837ac1e85fd1e241af225908b6a0c3d3a44d6b866e732_00400000' -> pg 7.ffffffff (7.3ff) -> up ([123,87,85], p123) acting ([123,87,85], p123)

# ceph pg deep-scrub 7.3ff


and here the ceph-osd.123.log snipped
