Hi, I had a successful ceph cluster that I am rebuilding. I have completely uninstalled ceph and any remnants and directories and config files. While setting up the new cluster, I follow the Ceph-deploy documentation as described before. I seem to get an error now (tried many times) : ceph-deploy mon create-initial command fails in gather keys step. This never happened before, and I’m not sure why its failing now.
