The SRU recently landed for https://bugs.launchpad.net/nova/+bug/1349888 introduced a potential upgrade regression if nova services are not upgraded all at once.

Basically, if nova-compute services are updated after nova-api services you will hit this issue if you perform volume operations. A simple solution, if possible, is to upgrade nova-compute services so that they are all in sync but I still want to remove the possibility for regression while keeping the fix from 1349888. I will propose an SRU shortly to resolve this.
