Public bug reported:

This is related to another bug:
https://bugs.launchpad.net/cinder/+bug/1398588/

If one attempts to resize a server with volume attachment information
that is inaccurate / contradicts Cinder's data (eg it thinks a volume is
attached that is not), it results in the server going into an
unrecoverable ERROR state:

Fault
