[Bug 1921399] [NEW] check_instance_shared_storage RPC call is broken

  Thread Previous • Date Previous • • Thread Next 
Public bug reported:

We broke check_instance_shared_storage() in this change:

https://review.opendev.org/c/openstack/nova/+/761452/13..15/nova/compute/rpcapi.py

Where we re-ordered the rpcapi client signature without adjusting the
caller. This leads to this failure:
