Thank you Devananda.

I just remember, that I had a package dependency issue when i tried to sync
the database for ironic as below:

ironic-dbsync --config-file /etc/ironic/ironic.conf create_schema

Traceback (most recent call last):
  File "/usr/bin/ironic-dbsync", line 6, in <module>
    from ironic.cmd.dbsync import main
  File "/usr/lib/python2.7/site-packages/ironic/cmd/dbsync.py", line
26, in <module>
    from ironic.common import service
  File "/usr/lib/python2.7/site-packages/ironic/common/service.py",
line 25, in <module>
    from ironic.common import config
  File "/usr/lib/python2.7/site-packages/ironic/common/config.py",
line 21, in <module>
    from ironic import version
  File "/usr/lib/python2.7/site-packages/ironic/version.py", line 16,
in <module>
    import pbr.version
ImportError: No module named pbr.version

I felt, that a python module - pbr , might be missing and installed
the below package:

python-pbr 0.8.0-1.el7 from epel7
Once i Installed the above package, I did not receive any traceback
errors as above.

Is it possible that, Installing the above package is causing the previous error?
or Do you suggest that it might be something else?

Also - Do you know of any other solution to the traceback error in
this email, and which dependency package
would i need to install to correct the same.


Thank you,

Lohit
