Hello Brad,
I manually deleted the py and pyc files under /usr/lib/python2.7/dist-packages and that seems to have worked. The ceph command does not complain right now. But I just noticed during the installation that there was an error installing some python packages:
TEST FAILED: /home/ssd/src/vanilla-ceph/ceph-install/lib/python2.7/site-packages/ does NOT support .pth files
error: bad install directory or PYTHONPATH
You are attempting to install a package to a directory that is not
on PYTHONPATH and which Python does not read ".pth" files from. The
installation directory you specified (via --install-dir, --prefix, or
the distutils default setting) was:
/home/ssd/src/vanilla-ceph/ceph-install/lib/python2.7/site-packages/
and your PYTHONPATH environment variable currently contains:
' '
It does not seem to be causing any errors for basic testing but I will try to eliminate this error. FYI, the strace command gave the following output (after deleting ceph_argparse from /usr/lib/python2.7/dist-packages):
ssd@msl-lab-ads01:~/src/vanilla-ceph/log_files$ strace -eopen ceph 2>&1|grep ceph_argparse

^C
Thanks all, for your help!

What output do you get from the following?
$ strace -eopen ceph 2>&1|grep ceph_argparse

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.
