Ian, If you are only running one server (with 2 OSDs), you should probably take a look at your CRUSH map. I haven't used ceph-deploy myself yet, but with mkcephfs the default CRUSH map is constructed such that the 2 replicas must be on different hosts, not just on different OSDs. This is so that if you lose that one host, you don't lose access to both copies of your data. If this is indeed your setup, the PGs will be stuck forever. While not recommended for a production setup, if you want to play around and get things to HEALTH_OK, you could modify your CRUSH map to just choose two OSDs instead of two hosts. - Travis On Wed, May 15, 2013 at 1:07 PM, <Ian_M_Porter@xxxxxxxx> wrote: > Hi Igor, > > > > I’ve tried that plus some other combinations and each time I get the > “ValueError: need more than 3 values to unpack” message > > > > I seem to have partial success, for instance I can run the ceph-deploy > activate command and that returns successfully, however if I check the > health of the cluster I get > > > > HEALTH_WARN 192 pgs degraded; 192 pgs stuck unclean; recovery 21/42 degraded > (50.000%), so somethings clearly not right > > > > My setup is very simple with my ceph admin node and ceph server node running > Ubuntu 12.04 within VMWare workstation.
