Stuck to attaching when a volume is attached to an instance

[Vincent Hou]

When I try to attach a volume to a running instance from the horizon interface, the status of the volume is stuck to attaching, even though the volume is successfully attached.
When I refresh the page, the status of the volume becomes attached.

If the spinner is there, it means it's actively fetching new data from Nova/Cinder periodically, and the data coming back still has the "attaching" status. If you want to verify that, set the "console" log level to "DEBUG" in your local_settings.py and watch what gets returned from the API calls in the log.

If you can find that the data coming back does not match what's being reflected in the updates to the table row, please reopen this bug with further details.

[Vincent Hou (houshengbo)]

The reason why the status of volume stuck to "attaching" is that there is error raised from the log of horizon, when I attach the volume to an instance.

There's something clearly wrong with how data is being returned from nova volume lately. This is the third report that end in a similar issue (though in different spots in the code). Related: https://bugs.launchpad.net/horizon/+bug/1004412

This needs to be investigated and fixed ASAP.
