To mount cephfs like that you need to have kernel support. As the Linux
kernel on CentOS 6.3 is version 2.6.32 and Ceph support wasn't added until
2.6.34, you need to compile your own kernel.
The better alternative is probably to install a kernel from
http://elrepo.org/tiki/kernel-lt . "lt" stand for "long term" and should be
fairly stable and "ml" is "mainline" which is even more current but because
of that not quite as stable (currently 3.7.6).
I had problems booting ml on some/most (dep. on the version) our
machines, plus it's a pain to track: there's a new one every day.
I do have lt running without problems and mounting cephfs, however, I
haven't gotten around to the actual ceph testing on it yet so I can't
say anything about ceph client's performance/stability on it. ("lt" is
3.0, as I understand it doesn't have the latest and greatest ceph module(?))
