============================================================================== AS-EXECUTED CAPTURE -- Stage 5 dc0 clean redeploy (ovn-central cert fix) Session 2026-08-04. Branch dc-dc-stage5-preconditions. ============================================================================== WHY THIS FILE: run-logged.sh opens an interactive script(1) subshell that only logs a live terminal; a Claude-driven session executes mutations as separate tool-call processes that such a subshell cannot capture. Per operator ruling 2026-08-04 ("Option 3, capture as you go"), each gated mutation's exact command and output is appended here instead -- the tool-call-friendly substitute that keeps the irreversible-step record (vault init, destroy-model) EXISTING and FINDABLE (docs/as-executed-log-convention.md purpose). CONVENTION per entry: [UTC] :: -> . Read-only measurements are NOT logged here (they are in the transcript); only mutations are. Status claims live in docs/CURRENT-STATE.md ONLY. Known coverage gap declared: read-only census/measurements this session live in the session transcript, not in this file. This file covers MUTATIONS only. ------------------------------------------------------------------------------ ## M-0 F3 redeploy prerequisite -- stage dc-node-etchosts.sh to the dc0 rack [2026-08-04] vcloud -> vr1-dc0-rack :: scp -p scripts/dc-node-etchosts.sh \ vr1-dc0-rack:/home/jessea123/repo-stage/scripts/dc-node-etchosts.sh -> rc=0 VERIFY (vr1-dc0-rack, sha256 first 16): dc-node-etchosts.sh staged=0f79de90c19e9f5a repo=0f79de90c19e9f5a MATCH mode=664 lib-net.sh (dep) staged=3e465ae7de3bf92d repo=3e465ae7de3bf92d MATCH RESULT: F3 CLOSED -- redeploy prerequisite satisfied. REVERT: rm ~/repo-stage/scripts/dc-node-etchosts.sh on the rack (restores prior staged set; the script is a redeploy input, not live cloud state). ## M.2 Path M teardown of the vr1-dc0 model [MUTATION, GA-R5 operator-ruled 2026-08-04] Operator ruling (verbatim selection): "Proceed with Path M.2 teardown now". Pre-teardown MAAS baseline (profile dc0, rack hot-kid): 10 machines, all Deployed, owner juju-vr1-dc0. juju storage empty (no storage flag). juju offers empty. [2026-08-04 ~18:2x] vr1-dc0-rack :: juju destroy-model vr1-dc0 --no-prompt (WITHOUT --force -- agents alive; --force orphaned the model + downed the controller on 08-03. WITHOUT --no-wait -- reserved for the agents-stopped stall.) DRAIN (progressive, hooks executing -- the proven path, NOT the 07-31 flat stall): 36 -> 35 -> 34 -> 30 -> 28 -> 27 -> 25 -> 24 -> 23 -> 22 -> 21 machines ... (in progress) juju models: vr1-dc0 state=destroying. DRAIN OUTCOME: graceful drain reached the tail then WEDGED flat at 15 machines (1 control host + 14 LXD containers) for ~12 min. Retry worker ALIVE (attempt 25 -> 28 -> 37 climbing) but count would not drop: 4 units stuck in workload error with failed teardown hooks their idle agents could not complete -- magnum/0 (identity-service-relation-departed), octavia/0 (certificates-relation-changed), ovn-central/0 (ovsdb-cms-relation-broken), placement/0 (identity-service-relation-departed). This is M.2's documented agents-can't-run-stop-hooks stall. Agents were EXECUTING (not stopped), so per M.2 --force was NOT auto-warranted; presented as a gated decision. INSTRUMENT NOTE (owned): first watcher counted juju status --format=json .machines and read 1 (collapses to top-level host during destroy, hiding the 14 containers) -> false STALL alarm. Real total = the "found N machines" retry line. Corrected. ## M.2b Clear the stall via juju resolved [MUTATION, GA-R5 operator-ruled 2026-08-04] Operator ruling (verbatim selection): "Try `juju resolved` on the 4 error units first". [2026-08-04] vr1-dc0-rack :: juju resolved --no-retry -m vr1-dc0 magnum/0 octavia/0 ovn-central/0 placement/0 -> rc=0 (--no-retry: skip the failing teardown hook rather than re-run it into the same failure; safe in a destroy -- MAAS re-images the machines.) RESULT: unblocked -- applications 53 -> 41 within ~30s; attempts climbing (37). New error units surface as the drain proceeds (barbican/0, designate/0 next), so continuing with a bounded resolve-loop (juju resolved --no-retry --all every ~25s) until the model is GONE (M.5 positive-signal verified). REVERT: n/a -- teardown is intended. ## M.2c Finish the stall via --force --no-wait [MUTATION, GA-R5 operator-ruled 2026-08-04] Operator ruling (verbatim selection): "Escalate: --force --no-wait now". CONDITION AT ESCALATION: resolve loop took the drain 15 -> 3 machines, then the last 3 records (control-01 + 0/lxd/2 + 0/lxd/18) went to machine-state STOPPED -- agents down, no teardown hook can run (the genuine M.2 agents-stopped stall that juju resolved cannot address). Model was 'destroying' (NOT 'dead'), so re-issuing is the documented escalation, not the forbidden dead-model re-issue. [2026-08-04 ~19:29] vr1-dc0-rack :: juju destroy-model vr1-dc0 --force --no-wait --no-prompt -> "Destroying model" ... 3 -> 1 -> 0 machines ... "Model destroyed." rc=0 RESULT (M.2 overall): TEARDOWN COMPLETE, CLEAN, NO ORPHAN. ORPHAN CHECK (the 08-03 failure -- did NOT recur): - juju models: only 'controller' (available); vr1-dc0 fully gone, not life:dead. - controller model API responds (juju status -m controller OK) -- 17070 up. - models now = [('admin/controller','alive')] -- no dead-model residue; add-model will not be refused. M.5(b) CASCADE CHECK (profile dc0): 10 machines, count UNCHANGED from baseline -> NO cascade. States: Ready 9 (role nodes, owner=None) + Deployed 1 (controller VM subtle-grouse). Exactly the expected post-teardown state. REVERT: n/a -- teardown is intended; rebuild is M.6 (add-model + rebuild). ------------------------------------------------------------------------------ ## M.5(c) proxy-survival post-checks (read-only, logged for the teardown record) dc-cache-proxy check dc0: PASS (apt-cacher-ng active :3142, serves archive+UCA 200) dc-snap-proxy check dc0: PASS (:3129, store API 200, CDN tunnel allowed, allowlist enforced) => M.5 ALL GREEN. Path M teardown complete + clean. Proceeding to M.6 rebuild. ## M.6 REBUILD ## Step 3.5 -- add-model + spaces + artifact source [MUTATION, gated] [2026-08-04] vr1-dc0-rack (D-138; runbook says voffice1 but that predates D-138) :: juju add-model vr1-dc0 -> "Added 'vr1-dc0' model with credential 'vr1-dc0-cred' for user 'admin'" rc=0 GATES (read-only): (a) artifact source inherited from model-defaults: apt-http-proxy=http://10.12.8.4:3142, snap-http[s]-proxy=http://10.12.8.4:3129, apt-mirror EMPTY. Correct per D-135 amendment (b) (dc0 on the caching PROXY, not the retired mirror). apt-mirror NOT set (Step 3.5's mirror text is STALE -- runbook-fold gap, flagged). (b) juju-spaces-check.sh vr1-dc0: PASS 0 fatal -- all six spaces present, none stale. REVERT: juju destroy-model vr1-dc0 (empty model; trivial). ## QUEUED -- NOT EXECUTED THIS SESSION (operator request 2026-08-04, mid-redeploy) Q1. "Queue a Tailscale installation for DC0 and DC1." DEFERRED (hard rule 1 -- new scope is logged mid-step, not run). NEEDS A RULING BEFORE EXECUTION, not just an ops task: it intersects ruled surfaces -- - D-107: Tailscale is the operator WORKSTATION / human-GUI path, NOT the DC nodes. - D-128: durable DC reach is the base-leg oneshot, explicitly NOT tailscale-on-host. - 2026-08-02 ruling: "VPN deferred to Roosevelt" (VPN class deferred). ACTION OWED: grep the exact D-107/D-128 text + the 08-02 VPN-deferred ruling, then put the DC-Tailscale question to the operator as a GA-R5 exchange (likely a new D-number, GA-R3 A1: decides DC access at every future standup). Do NOT install until ruled. ## Step 1.2b -- metal-internal /etc/hosts cloudinit (the ovn-central cert fix) [MUTATION, gated] FIRST ATTEMPT FAILED -- delivery-mechanism defect found: juju model-config REJECTED the config: "cloudinit-userdata: runcmd not allowed, use preruncmd or postruncmd instead" (rc=1, nothing set). The 08-04 fix proved the CONCEPT (manual /etc/hosts -> cert) but its DELIVERY (cloudinit-userdata) was never live-tested; the harness graded rendered YAML (cloud-init accepts runcmd) not juju acceptance (juju forbids it). Classic can't-see-the-live-apply green harness. FIX (repo change, delivered with discipline): scripts/dc-node-etchosts.sh: render key runcmd: -> postruncmd: (repo sha 0f79de90.. -> 107fc197..); + inline comment forbidding revert. tests/dc-node-etchosts: switched to postruncmd; NEW T10 asserts a juju-accepted key + rejects bare runcmd (the missing gate). Harness 10/10; T10 MUTATION-PROVEN to fail (revert to runcmd -> 5 FAIL). Re-staged to rack (sha 107fc197 verified). RE-RUN (live delivery test that was missing): [2026-08-04] vr1-dc0-rack :: JUJU_MODEL=vr1-dc0 bash scripts/dc-node-etchosts.sh apply vr1-dc0 -> "OK: set" (juju ACCEPTED postruncmd) JUJU_MODEL=vr1-dc0 bash scripts/dc-node-etchosts.sh check vr1-dc0 -> OK, carries 10.12.12.0/22 mapping, rc=0 GATE: check exit 0. On-node /etc/hosts delivery VERIFY-AT-PROVISION after Step 1.4. REVERT (model-config): juju model-config -m vr1-dc0 --reset cloudinit-userdata. ## Step 4.2 dry-run gate (read-only, logged for the deploy record) 9 machines "0"-"8", every machine tags=openstack-vr1-dc0, (3 control/2 compute/4 storage); ceph-osd->5-8, nova-compute->3-4; no overlay error; rc=0. GATE PASS. ## (below appended as each further mutation executes -- NEXT: Step 4.3 deploy, operator-gated)
