Store shards deployed before #199 was merged cannot easily be updated with the latest revision of kube-thanos, because of 2 changes made to StatefulSet.spec: volumeClaimTemplates, and selector. The error I'm seeing from Kubernetes is updates to statefulset spec for fields other than 'replicas', 'template', and 'updateStrategy' are forbidden.

This isn't a huge problem because of being able to jsonnet-patch around this, but was still a little time consuming to diagnose and fix, and I wonder if there's a reasonable place to document this to save future users the time.

This is probably best to be put in the CHANGELOG.md and then to be announced by the time we publish a new release.
