Performance/Scalability

Gate failures (haleyb)

• Current failure rate: https://goo.gl/L1WODG
  • Functional test failures seen in the Check queue, root cause yet to be identified.
  • Single node check job failure rates are more when compared to neutron full job.
  • Multi-node check job failure rate have gone up from last week
    • Bugs in Nova:
      • https://bugs.launchpad.net/nova/+bug/1524898 (Volume based live migration aborted unexpectedly)
      • https://bugs.launchpad.net/nova/+bug/1535232 (live-migration ci failure on nfs shared storage)
• Debug the gate in the current failure state (Identify owners who can own this)
• https://bugs.launchpad.net/neutron/+bug/1515360 - Tempest "SSHTimeout" failures (GOOD TO HAVE) - This patch seem to have some timing issues and so we are seeing more failures for the pings.
• https://drive.google.com/file/d/0B4kh-7VVPWlPMkdrQWFFdjNsSnM/view?usp=sharing - Logstash failures captured. Any logstash errors can be captured here

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

Open Discussion

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.
