Swift clients not able to create containers when using Ceph's radosgw, why?

Solution In Progress - Updated -

Environment

  • Red Hat Enterprise Linux 7

  • Inktank Ceph Enterprise 1.2 {Firefly v0.80.5}

  • python-swiftclient v2.1.0-2.el7ost

Issue

  • Swift clients are not able to create containers when using Ceph's radosgw.

  • The swift command is returning 400 Bad Request when viewed with --verbose and --debug options

# swift --verbose --debug --os-storage-url XXXX--os-auth-token {XXXXXXX}post {XXXXX}

Resolution

  • Downgrade the python-swiftclient 2.0.X package:
# yum downgrade python-swiftclient

Root Cause

  • An installation of Openstack on RHEL7 contains the python-swiftclient v2.1.X package.

  • This package does not currently create containers correctly when the radosgw is integrated into the Openstack solution.

  • When trying to create containers, in Horizon or with the swift client from python-swiftclient (in version 2.1.x), we get an HTTP 400 error message.

Diagnostic Steps

  • Verify version of python-swiftclient installed:
# rpm -q python-swiftclient

  • Attempt to create container in horizon or the swift command line

  • Try the same activity, using curl
