Hi Cinder team,
We are going to implement storage-assisted volume migrate in our driver between
different backend storage array or even different array of different vendors.
This is really high-efficiency than the host-copy migration between different
array of different vendors.
To implement this, we need to call other backend's method like create_volume()
or initialize_connection(). We can call them like the cinder/volume/manage.py:
rpcapi.create_volume(ctxt, new_volume, host['host'],
None, None, allow_reschedule=False)
or
conn = rpcapi.initialize_connection(ctxt, volume, properties)
And my question is: Does the OpenStack community(or Cinder team) allow driver
to call rpcapi in order to call other driver's method like create_volume() or
initialize_connection()?
Thanks for any input!
