Try using 'ceph-deploy osd create' instead of 'ceph-deploy osd prepare' and 'ceph-deploy osd activate' when using an entire disk for an OSD. That
will create a journal partition and co-locate your journal on the same disk with the OSD, but that's fine for an initial dev setup.

Hi Peter,
I agree, setting up Ceph isn't very complicated. I posted to the list on
10/03/16 with the initial problem I have run into under the subject "Can't activate OSD". Please refer to that thread as it has logs, details of my setup, etc.
I started working on this about a month ago then spent several days on it and a few hours with a couple different people on IRC. Nobody has been able to figure out how to get my OSD activated. I took a couple weeks off and now I'm back at it as I really need to get this going soon.
Basically, I'm following the quickstart guide at http://docs.ceph.com/docs/jewel/start/quick-ceph-deploy/ and when I run the command to activate the OSDs like so:
ceph-deploy osd activate ceph02:/dev/sdc ceph03:/dev/sdc
I get this in the ceph-deploy log:

More details in other thread.
Where am I going wrong here?
Thanks!
