Re: Still have orphaned rgw shadow files, ceph 0.94.3

Ok. I'm not too familiar with the inner workings of RGW, but i would
assume that for a bucket with these parameters:

   "id": "default.8873277.32",
   "marker": "default.8873277.32",

Tha it would be the only bucket using the files that start with
"default.8873277.32"

default.8873277.32__shadow_.OkYjjANx6-qJOrjvdqdaHev-LHSvPhZ_15
default.8873277.32__shadow_.a2qU3qodRf_E5b9pFTsKHHuX2RUC12g_2
