Hi,
In the end this was tracked back to a switch MTU problem, once that was fixed any version of ceph-deploy osd prepair/create worked as expected.
Thanks

Did the prepare command succeed? I don't see any output referring to 'ceph-deploy osd prepare'. If this command also fails maybe there's a hint, and the activate command is only a consequence of that failure?
Zitat von Alan Johnson <alanj@xxxxxxxxxxxxxx>:
I did have some similar issues and resolved it by installing parted 3.2 (I can't say if this was definitive) but it worked for me. I also only used create (after disk zap) rather than prepare/activate.

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.

On Wed, Oct 05, 2016 at 01:17:52PM PDT, Peter Maloney spake thusly:
What do you need help with specifically? Setting up ceph isn't very
complicated... just fixing it when things go wrong should be. What
type of scale are you working with, and do you already have hardware?
Or is the problem more to do with integrating it with clients?
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!
