** provider_location is too small to store all storage nodes and other data; enlarge to 4kB?
 
** cinder/brick/initiator/connector.py factory() used, AND cinder/volume/target/drbd.py ??

** '''Led by:''' thingee
 
** Problem: The OpenStack Infra team has to deal with questions from all projects on how to setup a third party CI.
 
** Idea #1: Is anyone willing to help the Infra team?
 
*** Ideally this person already has their third party ci.
 
*** Will be pinged on IRC from infra when someone has a question with third party CI help in Cinder.
 
*** Should watch infra mailing list for Cinder related CI questions.
 
**** If there are requests to reenable a CI, this person should be able to verify that things have been more stable and give the OK so infra can turn things on.

'''July 23th, 2014 16:00 UTC'''
 
 
 
* J2 Milestone (DuncanT)
 
** JGriffith favours a freeze exception for all drivers taht currently have code / BP up, but bouncing all new ones
 
** Review priorities
 
*** Driver specs
 
*** CG groups - a big change that requires driver changes, so needs lots of eyes and time for driver maintainers to do their thing too:  https://review.openstack.org/#/c/104743/
 
*** Pool scheduling - https://review.openstack.org/#/c/98715/
 
*** Others?
 
* Plug for weekly 3rd Party CI meeting (Mondays at 18:00 UTC [1 pm Central]) (jungelboyj)
 
** I attended this week's meeting and gave a high level status.  They are looking for more participation.
 
* ProphetStor Cinder drivers (stevetan)
 
** Get feedback on progress of our DPL driver and documentation required https://review.openstack.org/#/c/95829/
 
** Get direction from community for our Federator SDS driver https://review.openstack.org/#/c/99616/
 
* Volume replication - work in progress (ronenkat)
 
** https://review.openstack.org/#/c/106718/2
 
* NFS Security, if there's time.
 
** https://blueprints.launchpad.net/cinder/+spec/secure-nfs

* Putting the fun back into cinder development.
 
**  There's been a mailing list thread recently about how nit-picky reviews are getting about typos, white space and the like, and how it is a motivation killer. I'm inclinded to agree - the formatting of the doc strings, fullstops at the end of comments etc doesn't actually improve the code much at all, and getting a -1 for it is a buzz kill of the highest order. Should we leave that sort of thing to the gate, and say that if there is no hacking check for it then it isn't important in general? (DuncanT)
 
 
 
* How to proceed with cinder/openstack requirements? python-dbus for https://review.openstack.org/99013, see mailing list conclusion http://lists.openstack.org/pipermail/openstack-dev/2014-July/040182.html (flip214)
 
* code churn, not sure where/when to start, fear of merge conflicts (flip214)
 
 
 
* Hitachi Block Storage cinder driver (tsekiyama)
 
** We want to get some feedback about how we can make this forward
 
** Review: https://review.openstack.org/#/c/90379/
 
 
 
* Log translations https://review.openstack.org/#/c/105665/ is still stuck - any thoughts? Options I can see: (DuncanT)
 
** A better technical solution - should be possible where the message format is not expanded outside the logging call i.e.:
 
Ok:
 
    <nowiki>
 
    LOG.warning("The flubigar id %d exploded messily", flu_id)
 
    </nowiki>
 
Not ok:
 
    <nowiki>
 
    msg = _("The flubigar id %d exploded messily") % flu_id
 
    LOG.warning(msg)
 
    </nowiki>
 
 
 
** We don't break up our message categories
 
*** This makes life harder for the translation team, makes us inconsistent with Openstack in general but keeps the code from descending into ugliness
 
** Related discussion on enabling translation (jungleboyj):
 
*** Have two patches awaiting approval:  Explicit import of _() https://review.openstack.org/105315 and enable lazy translation:  https://review.openstack.org/105561
 
*** Need to get these merged so we are running with the changes.
 
* 3rd Party CI (jungleboyj):
 
** Clarification on when drivers are going to be removed.

** Eric Harney is fine with this and planned to do this for Juno anyway ([https://blueprints.launchpad.net/cinder/+spec/remotefs-snaps see his blueprint]). I've put it on the agenda to make sure others also agree with this approach.
