Swift upgrade issue - 1.9.0 to 1.10.0

Hi,

We are trying to upgrade swift 1.9.0 to 1.10.0.

The ubuntu OS is 13.10. After the upgrade, all the features are working fine. Except, swift-ring-builder command which give below error :

root@swift-proxy-2:~# swift-ring-builder /etc/swift/account.builder Traceback (most recent call last): File "/usr/local/bin/swift-ring-builder", line 31, in <module> from swift.common.ring.utils import parse_search_value, parse_args, \ ImportError: cannot import name parse_args

We have upgraded it using the tar.gz available at https://launchpad.net/swift/havana/1.10.0/+download/swift-1.10.0.tar.gz. The upgrade steps included :

1) stop all the relevant swift services, python setup.py install command and then start services.

Above was done first on storage nodes followed by proxy server.

Any help would be appreciated.

Regards,

Viral
