I think you need to add the following..

enable experimental unrecoverable data corrupting features = newstore rocksdb

Thanks & Regards

Subject: [ceph-users] osd does not start when object store is set to "newstore"

Hi,

I built and installed ceph source from (wip-newstore) branch and could not 
start osd with "newstore" as osd objectstore.

$ sudo /usr/bin/ceph-osd -i 0 --pid-file /var/run/ceph/osd.0.pid -c 
/etc/ceph/ceph.conf --cluster ceph -f
2015-05-08 05:49:16.130073 7f286be01880 -1 unable to create object store
$

#### ceph.config ( I have the following settings in ceph.conf)

[global]
osd objectstore = newstore
newstore backend = rocksdb

enable experimental unrecoverable data corrupting features = newstore

The logs does not show much details.

$ tail -f /var/log/ceph/ceph-osd.0.log
2015-05-08 00:01:54.331136 7fb00e07c880  0 ceph version  (), process ceph-osd, 
pid 23514
2015-05-08 00:01:54.331202 7fb00e07c880 -1 unable to create object store

Am I missing something?

Regards
Srikanth
