Cinder failed to commit reservation

[Ivan Lozgachev]

The error happened only once during Rally test boot-from-volume-and-resize.yaml. I tried to reproduce it one more time but no luck.

Found on MOS 9.0 build 308

Environment:
  1 controller
  2 compute
  1 cinder
  (all quotas are set to -1)

Steps to reproduce:
  Run Nova Rally test boot-from-volume-and-resize.yaml
  Check cinder-all.log file on controller node

Expected result:
  No errors

Actual result:
  Cinder raised error

From cinder-all.log file:

I can't reproduce this bug on my environments. It was reproduced only once, so I've changed priority to Medium
