Hi Groka, Cinder & Nova devs,
Following up this thread from the context of
To summarise the discussion:
- initialize_connection shouldn't be called more than once, as it
may mess up some drivers.
- To (safely) refresh connection_info a new api for cinder is required.
- a patch to nova, such as #579004 could make a call to this new api
to refresh connection info on events such as reboot.
Is there any other context to this issue I've missed or an alternate
path to solving this?
Does the creation of a new api for cinder have any implications for
being able to backport this patch for nova?
What would be the process for me to kick off this work?
Thanks for your help,
