Not really a new bug, but turns out this wasn't generally known
or documented anywhere. As a heads up for folks we'll put in a
known issue into the release note for N.

issues:
- When running Nova Compute and Cinder Volume or Backup services on the same
host they must use a shared lock directory to avoid rare race conditions
that can cause volume operation failures (primarily attach/detach of
volumes). This is done by setting the "lock_path" to the same directory
in the "oslo_concurrency" section of nova.conf and cinder.conf. This issue
affects all previous releases utilizing os-brick and shared operations
on hosts between Nova Compute and Cinder data services.
