Now we don’t have to list all the instances of the shares for a user in order to show how much they

are using.

Real world use case (Huawei public cloud)
API change, backwards compatible

N e w i n Q u e e n s – s ma r t e n s u r e

s

h a r e

When the manila-share service starts up an internal method called ‘ensure-share’ is run to

reconcile manila’s view of the back end state as maintained in its database with the back end’s actual state.

Export locations could have changed – e.g. back end became IPv6 capable.
Back end software could have been upgraded
Driver can ensure that back end state is correct or update manila’s state as appropriate.
Most of the time nothing needs to be done but if the back end has many shares and each one

needs to be checked startup can be delayed.

So we introduced a mechanism where the manager calls get_backend_info() and the back end

returns a dictionary of key/values for potential update.

Manager computes a hash of these and compares it with its last hash. If these match, nothing

needs to be done.

If they don’t match the manager runs ensure_shares() which returns a list of model updates for

each share on the back end.
