Description

After we've enabled DR replication on the secondary leader the existing cluster followers will be resealed with the primary clusters encryption keys. We have to unseal the followers to make them available. To ensure that we absolutely take every precaution before attempting to unseal the followers we now verify that the secondary leader is the cluster leader, has a valid merkle tree, and is streaming wals from the primary cluster before we attempt to unseal the secondary followers.

TODO only if you're a HashiCorp employee

  • Backport Labels: If this PR is in the ENT repo and needs to be backported, backport
    to N, N-1, and N-2, using the backport/ent/x.x.x+ent labels. If this PR is in the CE repo, you should only backport to N, using the backport/x.x.x label, not the enterprise labels.
    • If this fixes a critical security vulnerability or severity 1 bug, it will also need to be backported to the current LTS versions of Vault. To ensure this, use all available enterprise labels.
  • ENT Breakage: If this PR either 1) removes a public function OR 2) changes the signature
    of a public function, even if that change is in a CE file, double check that
    applying the patch for this PR to the ENT repo and running tests doesn't
    break any tests. Sometimes ENT only tests rely on public functions in CE
    files.
  • Jira: If this change has an associated Jira, it's referenced either
    in the PR description, commit message, or branch name.
  • RFC: If this change has an associated RFC, please link it in the description.
  • ENT PR: If this change has an associated ENT PR, please link it in the
    description. Also, make sure the changelog is in this PR, not in your ENT PR.
