Elasticsearch 7.10.2 rollout plan
Closed, ResolvedPublic
Actions

Description

Prerequisites:

Schedule:

  • Starting week: Aug 29, 2022
  • Train version: Expecting 1.39.0-wmf.28 with branch cut on Sept 5.

Once all prerequisites are verified define the week starting date for the rollout:

Plan:

  • Week 1
    • Monday: Upgrade cloudelastic to elasticsearch 7.10.2 and verify that updates are flowing properly
    • Tuesday: Merge apifeatureusage prep. Start the rollout on codfw and monitor updates
    • After the branch cut, merge:
      • Merge the es710 branch into master in vendor, CirrusSearch, and Elastica repositories
    • Note the mediawiki version they'll land into and update the mw-config patch (https://gerrit.wikimedia.org/r/c/operations/mediawiki-config/+/824787) with it
    • Add these patches as risky in a comment to the corresponding deployment blockers phab task
    • Soon after merging upgrade deployment-prep to elasticsearch 7.10.2 and verify search functions/error logs
    • Once codfw is fully upgraded deploy the mw-config patch to switch search traffic based on the mw train version
  • Week 2
    • Wait for the train to rollout everywhere and verify search functions/error logs, search traffic will start flowing to codfw as the train rolls forward, be available to releng when syncing wiki groups
  • Week 3 (after the expected train version is running everywhere and unlikely to be rolled back)

Things to watch out:

  • CirrusSearch maintenance scripts: completion suggester, dump index, saneitizer

Rollout is currently progressing. Found one regression from logs:

Search backend error during comp_suggest search for 'mediaw' after 131: x_content_parse_exception: [1:516] [terms_lookup] unknown field [1]

Looks to be an issue with a php array being encoded to a json object. Patch (https://gerrit.wikimedia.org/r/c/830214/) scheduled for backport window today. Otherwise it all looks reasonable so far.

eqiad is now running elastic 7 as well. The completion indices will rebuild overnight, we should be able to verify them tomorrow and switch traffic back to it's local datacenter instead of all being routed to codfw.
