Hi John, Thanks for your response. Here is what I am setting them to: I am installing all binaries in the folder: ~/src/vanilla-ceph/ceph-install. So the folder contains the following subfolders: ssd@msl-lab-ads01:~/src/vanilla-ceph/ceph-install$ ls bin etc include lib libexec sbin share ssd@msl-lab-ads01:~/src/vanilla-ceph/ceph-install$ ls lib/python2.7/site-packages/ ceph_argparse.py ceph_rest_api.py rbd-2.0.0-py2.7.egg-info ceph_daemon.py ceph_volume_client.py rbd.so cephfs-2.0.0-py2.7.egg-info rados-2.0.0-py2.7.egg-info rgw-2.0.0-py2.7.egg-info cephfs.so rados.so rgw.so Here are my paths: ssd@msl-lab-ads01:~$ echo $PATH /home/ssd/src/vanilla-ceph/ceph-install/bin:/home/ssd/src/vanilla-ceph/ceph-install/sbin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games ssd@msl-lab-ads01:~$ ssd@msl-lab-ads01:~$ echo $PYTHONPATH /home/ssd/src/vanilla-ceph/ceph-install/lib/python2.7/site-packages: ssd@msl-lab-ads01:~$ ssd@msl-lab-ads01:~$ echo $LD_LIBRARY_PATH /home/ssd/src/vanilla-ceph/ceph-install/lib:/home/ssd/src/vanilla-ceph/ceph-install/lib/x86_64-linux-gnu I just realized there is another ceph_argparse in my system in /usr/lib but since my path is pointing to another folder, it should be looking at the contents of that folder, right? ssd@msl-lab-ads01:/usr/lib/python2.7/dist-packages$ ls ceph ceph_argparse.py ceph_deploy/ cephfs.py ceph_rest_api.py ceph_argparse.pyc ceph_deploy-1.4.0.egg-info/ cephfs.pyc ceph_rest_api.pyc Thanks!

I usually use the long form to setup the cluster. The mon setup is fine but when I create an OSD using ceph osd create or even check the status using ceph -s after the monitor is setup, I get this error. The PATH, LD_LIBRARY_PATH and PYTHONPATH have been set accordingly. You don't say *what* you set those variables to, so I can't form an opinion on whether you've set them correctly. However, given that descsort_key is a relatively recent addition to ceph_argparse, and your python exception shows it's finding the module but not that particular symbol, it seems fairly likely that you have some other ceph_argparse on your system that is being picked up instead of the one you've just installed (i.e. your PYTHONPATH is wrong).
