I've attached the previous thread where I ran into the issue with --no-adjust-repos. Not sure if attachments are allowed by the list, if it doesn't get through let me know and I can forward it to you.
To summarize, it would let me work around proxy requirements during "ceph-deploy install", but then I would run into an issue during when attempting "ceph-deploy mon create". After resolving the proxy issue and removing --no-adjust-repos the issue during "ceph-deploy mon create" disappeared. The assumption is that they are related but that would require more detailed investigation to prove. See attachment for details.
To reproduce (at the time) I was just running Ubuntu 12.04.2 with 3.6.10 kernel, then installing ceph-deploy and doing a ceph-deploy new, ceph-deploy install with --no-adjust-repos, and then ceph-deploy mon create where I would get hung up on what appears to be an invalid argument --cluster to ceph-mon. After removing --no-adjust-repos same steps would complete successfully. The problem may be that the --cluster flag wasn't supported by the version of ceph installed.

I think a version issue is likely. I was running "ceph-deploy install" on Ubuntu 12.04.2 with the --no-adjust-repos switch because the wget it would execute was hanging for me. Ultimately the wget problem seemed to be a proxy issue. Even though I had proxy configured globally (/etc/environment), and could successfully execute my own wgets on the command line, I ultimately had to directly configure the proxy in the wget configuration (/etc/wgetrc) to avoid the hang in "ceph-deploy install". Once that was resolved, I removed the --no-adjust-repos switch from "deph-deploy install", and that in turn seemed to resolve the later failure in "ceph-deploy mon create". It all runs fine for me now. Unfortunately I did not specifically track the resulting ceph versions when deploying with and without --no-adjust-repos. I can tell you after resolving the issue I am currently running ceph-deploy 1.2.6 and I assume it is deploying Ceph 0.61.
What's the best way to check the Ceph version on a running cluster?
