Hi!

At the Cinder Midcycle Meetup in January we've created a list of
developers answers to "if you would have time what would you want to
sort out in Cinder?". The list can be find at the bottom of etherpad
[1]. It may seem a little vague for someone not into Cinder's internals,
so I can provide some highlights:

* Quotas - Cinder have issues with quota management. Right now there are
efforts to sort this out.
* Notifications - we do not version or standardize notifications sent
over RPC. That's a problem if someone relies on them.
* A/A HA - there are ongoing efforts to make cinder-volume service
scalable in A/A manner.
* Cinder/Nova API - the way Nova talks with Cinder needs revisiting as
the limitations of current design are blocking us.
* State management - the way Cinder resources states are handled isn't
strongly defined. We may need some kind of state machine for that? (this
one is controversial ;)).
* Objectification - we've started converting Cinder to use
oslo.versionedobjects back in Kilo cycle. This still needs to be finished.
* Adding CI that tests rolling upgrades - starting from Mitaka we have
tech preview of upgrades without downtime. To get this feature out of
experimental stage we need a CI that will test it in gate.
* Tempest testing - we should increase our integration tests coverage.

If you're interested in any of these items feel free to ask me on IRC
(dulek on freenode) so I can point you to correct people for details.

Apart from that you can look through the blueprint list [2]. Note that a
lot of items there may be outdated and not fitting well into current
state of Cinder.
