Conversation
The TNF setup gate in waitForEtcdBootstrapCompleted only checked EtcdRunningInCluster, which the bootstrap teardown controller sets before removing the etcd-bootstrap member (it is the signal bootkube watches to proceed with teardown). TNF setup could therefore start pacemaker while etcd-bootstrap was still a cluster member. The podman-etcd resource agent requires exactly 2 members and refuses to set the learner_node attribute when it sees 3, deadlocking the installation. Gate TNF setup on EtcdBootstrapMemberRemoved in addition, via a new ceohelpers.IsEtcdBootstrapMemberRemoved helper. If the member is not yet removed, return an error and let the job controller startup backoff retry. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

… fix Inject a 3-minute sleep between IsBootstrapComplete and MemberRemove() in removeBootstrap() to force the race window open. Placed after the bootstrap-complete check so pre-completion syncs return instantly. Extend sync() context timeout to 10m to accommodate. With the fix (commit 1), the TNF gate should retry with "etcd-bootstrap member has not been removed yet" for ~3 minutes, then proceed once the member is removed. Without the fix, the RA would deadlock with "found 3 members, need 2". DO NOT MERGE — reproducer for verification only.

🩺 Stability & Availability | 🟠 Major | ⚡ Quick win
Gate the four-minute delay instead of sleeping in every path.
The TEST ONLY comment does not change execution. The sleep runs in both complete-bootstrap cases in pkg/operator/bootstrapteardown/bootstrap_teardown_controller_test.go, Lines 274-408, so the unit test suite waits at least eight minutes before MemberRemove(). It also blocks the controller worker and ignores cancellation.
Make the delay injectable or feature-gated. Use no delay in normal tests and builds. Enable four minutes only for the cluster-bot reproducer. Implement the wait with a context-aware timer.
As per path instructions: Go code must use context.Context for cancellation and timeouts.

Align the reproducer delay with its stated duration.
The timeout comment specifies a 4-minute sleep, but the delay comment, log, and time.Sleep call use 3 minutes. Use one duration so the reproducer holds the intended race window.
