Unable to build Ceph from source code

[hemant surale]

Hi Community,
 I have tried to build ceph from source code i.e. v0.48 tarball .
After proceeding to all steps given at official site . when I execute
"service ceph start " it gives following error

-----------------//Error ------------------------------------
root@atish-virtual-machine:~# service ceph start
/etc/init.d/ceph: 37: .: Can't open /usr/lib/ceph/ceph_common.sh
-----------------------------------------------------------------

As well as I have created ceph.conf .. and when I execute "mkcephfs -a
-c /usr/local/bin/ceph.conf -k ceph.keyring" it gives following error

-----------------//Error ------------------------------------

So, clearly something went wrong with the installation step, and this 
file was not created.  How did you install after building?

^^ this is a pretty good clue.  It says the filesystem you've chosen for 
your OSD  has limited size for storing xattrs.  You should enable the 
filestore_xattr_use_omap option.  See
http://ceph.com/docs/master/config-cluster/file-system-recommendations/
