Hi guy's, I am totally new to Ceph deploy and I have succefully install ceph cluster on a Admin node and able to active it by One monitor and two OSD. After creation of Ceph Cluster I checked the Ceph Health Status and The output was OK. With that success I started to move to next stage for Rados Gateway. Untill 90% of work there was no any error but when I moved with stage python s3test.py I am facing the error. It's kind request to share your views to solve the error.
