  • Remove XenAPI driver (https://review.openstack.org/#/c/123162/) (DuncanT)
    • Should we go through deprecation?
    • There's an HP MSA driver that is unmaintained, unCIed and as far as we know unused, so we need a policy
      • Might have found a maintainer (DuncanT)
  • Please remember we're coming up to RC so lots of testing and bug fixing please, not just getting stuff ready for Kilo opening!

  • https://review.openstack.org/111659 - DuncanT
    • Should cinder be doing this, or should cinder remain an API that does exactly what it says on the tin and let neutron/nova be 'smarter' if it wants?
    • Should we be changing API behaviour? Should we be changing it just before milestone 3?

  • 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)
  • 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:

   
    LOG.warning("The flubigar id %d exploded messily", flu_id)
    

Not ok:

   
    msg = _("The flubigar id %d exploded messily") % flu_id
    LOG.warning(msg)
    
    • 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):
  • 3rd Party CI (jungleboyj):
    • Clarification on when drivers are going to be removed.

  • 3rd Party CI (jungleboyj)
    • What tempest test cases to run?
    • iSCSI only? What about for FC only drivers then?
    • Progress on where to record results?
  • SSH host keys (jungleboyj)
  • Dynamic multi-pools (navneet)
  • cinder-specs (jgriffith)
    • Specs repo is live
    • Process
    • Reviews

May 21st, 2014 16:00 UTC

  • Consistency Groups (xyang)
    • A few people have concerns on the restriction of one volume type per CG. Should we allow one CG to have multiple volume types on the same backend? Let's discuss about it.
  • Third-Party CI (jgriffith)
    • Who's started, who's planning to and how can we help support each other to get this going smoothly
  • Moving GlusterFS snapshot code into the NFS RemoteFs driver (mberlin)
    • The GlusterFS snapshot code using qcow2 snapshots is useful for all file based storage systems. I would volunteer to move the GlusterFS snapshot code into the general RemoteFs driver - making it easier to get our driver accepted ;-)
    • Eric Harney is fine with this and planned to do this for Juno anyway (see his blueprint). I've put it on the agenda to make sure others also agree with this approach.
