Closed, ResolvedPublic
Actions

Description

Cassandra 3.11.3 has been released; We should evaluate whether it makes sense to upgrade our environment(s).

3.11.2 clusters

  • RESTBase
  • Session storage
  • RESTBase-dev
  • RESTBase deployment-prep
  • Session storage deployment-prep

Upgrade sequence

IMPORTANT: Read this if you came here trying to understand why Puppet has been disabled!
  1. Disable Puppet to prevent package pinning from downgrading the packages
  2. Upgrade packages
  3. Perform rolling restarts
  4. Upload 3.11.4 packages to APT repository
  5. Update Puppet to pin 3.11.4 (instead of 3.11.2)
  6. Re-enable Puppet on all hosts
  7. Apply Gerrit with non-normative configuration changes
  8. Perform rolling restarts

Applicable staging/test environments have been updated to 3.11.4 and no issues are apparent. If this continues to look OK, and there are no objections, I will upgrade the production sessionstore cluster tomorrow (technically, it is not yet in production).j

The session storage cluster has been upgraded, and things look Good. If I hear no objections, I will upgrade a canary node in each datacenter of the RESTBase cluster on Monday, and plan to upgrade the remaining nodes on Tuesday if everything checks out.

That would be restbase1016 & restbase2011 specifically, and (due to the WMF holiday), s/Tuesday/Wednesday/ & s/Monday/Tuesday/
