Need to escalate the nova patch for the live migration. Since we have the tempest test running right now, we need someone from the nova team to take a look at the nova live migration patch.

Revision as of 14:20, 28 September 2016

The OpenStack Networking L3 DVR Sub-team holds public meetings as advertised on OpenStack IRC Meetings Calendar. If you are unable to attend, please check the most recent logs.

Meetings

Agenda

Meeting September 21st, 2016

Announcements (haleyb)

  • When adding items below I'd like to try to get feedback on whether they are a MUST FIX, SHOULD FIX, or GOOD TO HAVE and TRIAGE ME

Topics for Discussion

Bugs (Swami)

All DVR bugs should be tagged and listed here: https://bugs.launchpad.net/neutron/+bugs?field.tag=l3-dvr-backlog

New Bugs this week

High Priority Bugs in progress

  • https://bugs.launchpad.net/neutron/+bug/1612192 (MUST FIX) - L3 DVR: Unable to complete operation on subnet (Related to HA)
    • Not sure this is critical any more, as it's mostly seen in the SFC and OVN jobs, ~0 in the dvr-multinode-full job

Categorized Bugs

Gate Test Failures

More Functional test failures seen in Gate.

RFE

Existing Functionality Broken Bugs

Scale and Performance Impact Bugs

New Features Bugs

Refactor or Cleanup Bugs

WishList Bugs

WatchList Bugs

Bugs Closed Recently

Performance/Scalability

Gate failures (haleyb)

Stable backports (haleyb)

Ihar created a page tracking all the potential backports from Mitaka to the stable releases. I have been going through it with the help of Swami to get stable/liberty, well, more stable. Bugs are removed from list as they merge.

We need to continue to be aggressive at proactively backporting fixes to the stable branches

This is a list of bugs with a fix that has been committed to the master branch, and are tagged with 'neutron-proactive-backport-potential+l3-dvr-backlog' (the wiki thinks the link is spam so I had to put a space in it)
