Hey,

We're still hoping to releasing 2012.2.1 on Thursday but we need to lock things down now to allow last minute regression testing.

So, please don't approve any more fixes for the branch until after the release. If there's something you think warrants an exception, leave a +2 with a comment explaining you're thinking and I'll make the call as release manager.

Thanks for the detailed updated and heads up about the approvals. There is one critical patch for Quantum: https://review.openstack.org/#/c/17033/. The problem that we encountered was if namespaces are disabled and the DHCP agents device is not the first device in the routing table (for example if the L3 agents tap device is created first), then instances will not receive IP addresses from the DHCP agent.

There are a couple of other patches pending review for Quantum in the stable branch (I am just testing prior to pushing them). They are not critical for this release and can wait till the next.

We've had a huge amount of activity in the last week, so I'm a little nervous that we might have broken something. The current "bugs fixed" tallies are:

79 nova
33 quantum
11 glance
 7 keystone
 3 cinder
 1 horizon

134 total

Things to note:

• It looks like there might be a regression on stable/folsom with ceph/rbd:

  https://bugs.launchpad.net/nova/+bug/1083818

  Adam Gandelman and Josh Durgin are chasing it.

• There's a very serious known issue with the image cache cleanup code when you're using shared storage:

  https://bugs.launchpad.net/nova/+bug/1078594

  The fix is invasive and risky, but there's a known workaround (i.e. disable the image cache manager) which Vish has documented in the release notes.

  We may just disable the image cache manager by default for the release.

• The Quantum linuxbridge plugin fix which allows us to move away from using libvirt's type="ethernet" has been merged, but it isn't really useful without the corresponding change to the Nova VIF driver.

  https://review.openstack.org/16223

  Given the limited number of users affected, maybe we can consider merging the Nova change before the release too.

  One detail here is that if we merge the Nova VIF change, we would need to warn users to update Quantum before Nova.

I have added the patch for this - https://review.openstack.org/17036

I am going to be spending the rest of the day testing the stable branches.

• Please add stuff to the release notes as it occurs to you:

Cheers, Mark.

Is it sufficient to just set remove_unused_base_images to False by default?

Cheers, Mark.

Adam did an awesome job of bisecting and fixing this issue:

https://bugs.launchpad.net/cinder/+bug/1083818

It appears that it needs to be backported to cinder stable/folsom too

Cheers, Mark.
