| Hi Max, I had the same issue (under Ubuntu 16.04) but I have read the ceph-deploy 2.0.0 source code and saw a "—-release" flag for the install subcommand. You can found the flag with the following command: ceph-deploy install --help It looks like the culprit part of ceph-deploy can be found around line 20 of /usr/lib/python2.7/dist-packages/ceph_deploy/install.py: … 14 def sanitize_args(args): 15 """ 16 args may need a bunch of logic to set proper defaults that argparse is 17 not well suited for. 18 """ 19 if args.release is None: 20 args.release = 'jewel' 21 args.default_release = True 22 23 # XXX This whole dance is because --stable is getting deprecated 24 if args.stable is not None: 25 LOG.warning('the --stable flag is deprecated, use --release instead') 26 args.release = args.stable 27 # XXX Tango ends here. 28 29 return args … Which means we now have to specify "—-release luminous" when we want to install a luminous cluster, at least until luminous is considered stable and the ceph-deploy tool is changed. I think it may be a Kernel version consideration: not all distro have the needed minimum version of the kernel (and features) for a full use of luminous.
