From b77d9a5baabe06c83841deaf4feb374a403a2783 Mon Sep 17 00:00:00 2001 From: michael Date: Thu, 6 Aug 2026 22:18:17 +0200 Subject: [PATCH 01/14] Extract shared infrastructure into simplyblock_lib (edge-clusters step 1) New sbcli-agnostic package (no imports from core/web/cli; persistence and models are injected) so the edge-clusters services can reuse the control plane's plumbing without duplication: - tasks/lease.py: TaskLease claim/refresh/heartbeat lifted from tasks_controller (which now delegates, keeping its public entry points). Fix: a successful claim/refresh now also stamps the caller's copy of the task, so a follow-up full-object write (marking RUNNING) no longer clobbers the committed owner back to its stale value. - tasks/runner.py: TaskRunner poll-loop base (cluster sweep, re-read, cancel finalize, retry ceiling, lease claim + heartbeat, exponential backoff, DB-wedge exit(1)) replacing the skeleton every tasks_runner_* hand-rolls; tasks_runner_fdb_backup converted as the reference (also gains a main() guard - it previously ran its loop at import). - monitors/: PollingService (sweep loop, error cadence, adaptive interval, wedge threshold) and PerItemSupervisor (thread-per-node respawn); device_monitor and health_check_service converted as references. - api/: v2 typed scalars + creation_response and AccessLogMiddleware (app.py and api/v2/util.py are now facades over the lib). - events.py, units.py, secrets.py: level-mirrored event logging, parse_size, and SecretStr unwrap helpers re-homed; former locations re-export. Tests: tests/unit/lib/ (75 tests, duck-typed fakes incl. a fresh-read atomic_update stand-in) and tests/integration/lib/ (lease CAS + runner end-to-end against real FDB). tox types now covers simplyblock_lib. Also adds docs/edge_clusters_analysis.md (codebase analysis and plan for the edge-clusters feature; this extraction is build-order step 1). Parity notes: UrlPath's validator was and remains inactive (bare callable in Annotated; v2 DTOs store absolute URLs that it would reject if wired) - documented in tests. parse_size's uppercase-decimal-kilo rejection quirk kept and pinned by test.

Only + sbcli-specific content is the hardcoded `FN_*` constants → replace with a registry. +- `controllers/tasks_controller.py:1-148` — `claim_task` (CAS via `db.atomic_update`), + `_task_lease_is_stale`, `refresh_task_lease`, `task_lease_heartbeat`. Zero coupling to + StorageNode/Cluster/rpc_client. +- `models/base_model.py` FDB read/write/chunked-scan (minus the `StorageNode` write-tripwire). + +What the library should **add** (this is where the 17× duplication lives): + +- A `TaskRunner` base class: poll loop, function_name filter, claim, heartbeat context, + retry/backoff bookkeeping (currently the task *body* mutates `retry` and the loop infers + failure-vs-deferral by diffing it — invert this contract), cancel/defer checks, FDB-wedge + self-restart (exists in exactly one runner today: `tasks_runner_sync_lvol_del.py`). +- A `PollingService(interval, adaptive=...)` and `PerNodeSupervisor` base for the ~12 monitor + services (two copy-pasted patterns: flat sweep loop, thread-per-node supervisor). Pure + boilerplate; edge gets per-item exception isolation and thread respawn for free. +- One lock primitive. We currently have four unrelated idioms: per-task host lease, + in-process inflight maps, FDB lock models (`restart_lock`, `lvstore_lock`, + `ClusterAddNodeLock`, …), and restart-claim fields on the StorageNode row. + +Known defects any new consumer would inherit — fix during extraction: +`get_task_by_id` scans the whole task table (no uuid index; date is baked into the FDB key); +two runners execute at module import (no `main()`); task GC is a side effect of +`storage_node_monitor`. + +### 1.2 API / security infrastructure — extract the v2 stack only + +- **v2 (FastAPI) is the library.** Cleanly generic already: `api/v2/_auth.py`, + `api/v2/_dependencies.py` (hierarchical resource resolution), `api/v2/util.py` (typed + scalars, `creation_response`), `api/v2/meta.py` (health/ready), `simplyblock_web/settings.py`, + `simplyblock_core/settings.py` (TLS), `simplyblock_core/utils/secrets.py`, plus the + `AccessLogMiddleware` + exception handlers currently inlined in `app.py`. +- **v1 (Flask) has essentially no reusable scaffolding** — inline hand-rolled validation. + Edge should be v2-only; do not build a v1 surface for it. +- Prerequisites before extraction: + - `app.py` has no router-registry seam — version gating and the legacy-redirect list are + hardcoded. Add a plugin point so an `edge` router tree mounts without editing app.py. + - `_dtos.py` (680 lines) and `_dependencies.py` are single-file monoliths across every + resource — split per-resource first. + - `simplyblock_web/utils.py` straddles three apps/frameworks — split into "v1 response + envelope" vs "shared validation patterns". +- **Two auth gotchas that bite edge directly:** + 1. v2 authorization hinges on a route parameter literally named `cluster_id` + (`_auth.py:135-157`). A resource tree not nested under `/clusters/{cluster_id}` is + authenticated but **not** authorized per-tenant. Edge resources must either nest under + the same path shape or we replace the parameter coupling with a real tenancy abstraction. + 2. Cluster-secret auth enumerates **all clusters** per request and compare-digests each + (`_auth.py:107-132`) — O(#clusters) per API call. Fine at 10 clusters, not at 500 edge + sites. Needs a keyed lookup (secret→cluster index or token embedding the cluster id). +- CLI: `cli.py` is 100% generated from `cli-reference.yaml`; adding an `edge-cluster` command + group is one YAML block + methods in `clibase.py`. The generic scaffolding worth + extracting from `clibase.py` is only ~120 lines (type factories, formatters, parser trio). +- KMS (`simplyblock_core/kms/`) is already an abstract interface (LocalKMS/Vault) — reuse as-is. +- Events: `events_controller.py` is a thin generic writer (needs only `.name` + + `.get_clean_dict()` from its subject) — trivially extractable. + +### 1.3 DB layer — reuse, don't abstract yet, but respect the scan rule + +There is **no swappable seam**: `base_model.py` and `db_controller.py` both speak raw `fdb` +(transactionals, range reads, direct key indexing). Introducing a Postgres facade now would +mean rewriting the persistence layer and re-proving `atomic_update`'s CAS semantics — +agreed with the thread conclusion: stay on the shared FDB, one CP, one DB. + +What edge **must** do from day one (the "no new table scans" rule): + +- Composite keys prefixed by `cluster_id` (the pattern `JobSchedule`/`EventObj`/`Backup` + already use) so all edge reads are bounded range reads. +- Name lookups via `name_index/`-style keys (the pattern exists: `lvol_name_lookup`), never + scan-and-filter. Note as prior art: v1 `POST /lvol` still does two full-table scans per + CSI CreateVolume despite the index existing — don't replicate that. +- ~35 existing `get_*` methods are full-table scans (list in the exploration notes); edge + code paths must not call them in loops. + +### 1.4 Proposed package shape + +``` +simplyblock_lib/ # new: shared, no sbcli imports + tasks/ # JobSchedule-equivalent, claim/lease, TaskRunner base + monitors/ # PollingService, PerNodeSupervisor + api/ # FastAPI scaffolding: auth, deps, util, meta, middleware + events/ # event writer + settings/ # TLS + web settings + kv/ # base_model persistence (thin; still FDB) +simplyblock_core/ # existing hyperscale logic, now importing simplyblock_lib +simplyblock_edge/ # new: edge cluster ops, edge monitors, edge task types +simplyblock_web/ # mounts core + edge router trees behind one app/auth +``` + +--- + +## 2. Kubernetes-control-plane-side limitations (beyond FDB load) + +### 2.1 Cross-cluster access is new + +Everything k8s-native in sbcli today assumes **in-cluster config of the CP's own cluster** +(`utils.get_k8s_*_client()` → `load_incluster_config`). Edge requires the CP to talk to N +*remote* kube-apiservers: + +- Need a per-edge-cluster credential store (kubeconfig / SA token + CA) in the Cluster model, + and a client factory keyed by cluster — touch every `patch_cr_*` / pod-management helper. +- v2 SA-token auth (`TokenReview`) validates against the **CP's** cluster only. An edge-local + CSI driver's projected SA token is meaningless to the central CP. Edge API clients must use + cluster-secret auth (see 1.2 gotcha #2) or the CP must run TokenReview against the *edge* + cluster's API — feasible, but new code. + +### 2.2 The snode-API gap is small for edge — because of partitions + +In k8s mode today, the CP calls the node agent, and the **agent** calls the k8s API from +inside the cluster (renders `storage_deploy_spdk.yaml.j2`, creates Jobs/Pods). So the +yaml-render + Job/Pod machinery already exists — it just sits on the wrong side of the wire. +Moving it CP-side is largely a relocation. + +Of the snode API surface, already replaceable with k8s API + SPDK RPC: + +- SPDK pod start/kill/is-up → create/delete/list namespaced pod (code exists in + `api/internal/storage_node/kubernetes.py`). +- Node liveness → `list_node` Ready condition; the pattern already exists in + `mgmt_node_monitor.K8sNodeBackend` (storage-node monitoring today is ICMP + snode API + + RPC — no k8s involvement; edge inverts that). +- Port block/unblock → `port_block.py` already prefers the SPDK RPCs + (`nvmf_port_block/unblock/get_blocked_ports`); the iptables fallback is legacy. + +The irreducible residue is (a) hardware discovery (`info()`/`scan_devices` — PCI NVMe lists, +NUMA hugepages, RoCE mapping) and (b) privileged host mutations (vfio bind, `nvme format`, +gpt partitioning over NBD, hugepage/kubelet orchestration). **The edge design mostly sidesteps +both**: nodes contribute pre-existing free *partitions* consumed as **AIO bdevs** — no PCI +driver binding, no nvme format, no partitioning by us, no NUMA topology work. What remains: + +- A minimal discovery step: which partitions/devices exist and are free. One-shot privileged + Job (or init container of the SPDK pod) publishing to a CR/ConfigMap — not a resident agent. +- Hugepages: SPDK needs some; on 2 vCPU boxes decide between a small static hugepage + allocation in the node spec vs `--no-huge`. Init-Job pattern exists but currently loops + back through `/snode/apply_config` — the hugepage math must move into the Job image. +- DHCHAP/PSK key files (`write_key_file`) → project a k8s Secret into the SPDK pod instead. + +### 2.3 WAN/slow-uplink assumptions baked into the CP + +- Monitors poll per-node every 3–30 s with LAN-tuned timeouts (`is_live` timeout 5 s, + retry 1); runners poll the task table every 3–10 s per cluster. At hundreds of edge sites + over slow links this needs: per-cluster-class intervals, jitter, strict timeout budgets, + and sharding of monitor services by cluster set. The existing per-node-thread supervisor + pattern scales to nodes, not to 500 clusters × RTT. +- Long-running API writes are fire-and-forget **threads inside the uvicorn worker** (202 + + thread dies with the worker; no idempotency token). Acceptable on a LAN, bad over WAN — + edge operations should be JobSchedule tasks from day one, never request-thread work. +- Status semantics: mgmt-plane unreachability must not mark storage down. The hyperscale + monitor already learned this (`UNREACHABLE` counts only with data-plane quorum; + `get_next_cluster_status` in `storage_node_monitor.py`). Edge needs the same separation, + but the "peer quorum" concept degenerates at n=1/2 — the uplink being down is the *normal* + failure mode and must map to `unreachable` (CP view) while the edge keeps serving. + The proposed edge status derivation (all offline → suspended; one of two offline → + degraded; else active) is a ~50-line pure function — do **not** reuse the ndcs/npcs + arithmetic. +- Autonomy: with no CP-driven failover at the edge, everything that must survive uplink loss + has to be SPDK-native: raid1 auto-resync on leg reappearance, nvmf reconnects, and — + critically — **no CP-held lock or task lease may gate edge IO**. + +### 2.4 FDB / API footprint (the caveat from the thread, made concrete) + +- Per-request cluster enumeration in v2 auth (see 1.2) — first thing that melts with many + edge clusters. +- `get_task_by_id` whole-table scan; monitors iterating `db.get_clusters()` every tick; + events/tasks retention keyed to one cluster's monitor. All linear in cluster count. +- Status vocabulary is duplicated as pydantic `Literal`s in `api/v2/_dtos.py` — adding edge + statuses (`degraded` exists for clusters; fine) or new task function names breaks v2 + serialization if the Literal isn't updated in the same change. + +### 2.5 Data-path items to verify in the SPDK fork (not CP, but gating) + +- raid1 rebuild on leg re-add: supported; verify behavior when the leg is an nvme-tcp bdev + that reconnects (bdev re-registration vs new bdev name). +- **raid5f rebuild**: upstream SPDK raid5f historically lacks rebuild support. "Replace a + partition → rebuild via raid" and "later add a device under the raid5" both depend on + this — needs an explicit fork-capability check; raid5f grow/reshape almost certainly + does not exist and "add device" may mean recreate-and-resync. +- 2 vCPU: single reactor + app thread; consider interrupt mode / dynamic scheduler to not + burn a core polling on an idle edge box. + +--- + +## 3. Operator / CSI — high-level impact + +### 3.1 Topology decision (the "CSI across two clusters" question) + +A CSI driver cannot span clusters: the node plugin must run where kubelet mounts volumes +(edge), and the controller plugin's sidecars (provisioner/attacher/snapshotter) watch +PVC/PV objects, which live in the **edge** cluster's kube API. So: + +- **CSI deploys entirely per edge cluster** (controller + node parts), but its controller is + just an HTTP client of the central management API — point it at the central endpoint over + the uplink. No CSI code split across clusters. +- Consequence: CSI must tolerate uplink loss gracefully — provisioning stalls (acceptable), + but NodeStage/NodePublish and health of already-attached volumes must not depend on the + CP. Today's node plugin gets connect info from `GET /lvol/connect` at stage time; cache it + (or persist it in the volume context at provision time) so remounts/reboots during an + uplink outage still work. +- Auth: the driver authenticates with the edge cluster's secret (SA TokenReview won't work + cross-cluster, see 2.1). + +### 3.2 Operator + +- Aligns with the existing plan (per the thread): CP install becomes its own CRD; SPDK pod + management moves from sbcli into the operator. For edge, the **central** operator manages + remote clusters → it needs the same per-edge kubeconfig plumbing as the CP (2.1), or — + simpler — a thin edge-local operator instance that only reconciles pods/yaml while the + central CP stays the source of truth. Recommend the latter: it keeps "edge keeps running + standalone" true for pod restarts too (kubelet restarts pods anyway, but CR-driven changes + queue up). +- New CRD: `EdgeCluster` (or `StorageCluster` with a profile field): nodes (1–2), per-node + device/partition list, uplink endpoint + credential ref. CR write-back + (`patch_cr_status/…`) must be parameterized by target cluster; today it hardcodes + in-cluster config. +- The CR contract is currently triple-encoded (connect-entry model, v2 DTOs, camelCase CR + patch dicts in `controllers/*_events.py`) and documented nowhere except e2e helpers — + edge is the forcing function to write it down before adding a fourth shape. + +### 3.3 Functions that don't exist at the edge (CSI/API surface diff) + +Available/unchanged: create/delete/resize volume, snapshots + clones on the local lvstore, +connect info (single path or the raid1-exposing node), QoS, encryption (KMS is central — +cache/lease DEKs edge-side or crypto volumes fail closed on uplink loss — needs a decision). + +Not available at edge (CSI/operator must degrade cleanly, API should reject early): + +- ha_type=ha multipath fan-out, secondary/tertiary roles, hublvol/JM machinery, distr — + the whole ultra data plane. Edge HA is the raid1 layer instead. +- Device migration tasks (`FN_DEV_MIG` family), cluster expand beyond 2 nodes, failure + domains, cloud IMDS metadata. +- Backups to the extent they assume the ultra stack — needs a per-feature check. + +Suggested mechanism: a capability field on the Cluster record (`cluster_type: hyperscale | +edge`), surfaced through the API, gating both CSI behavior (StorageClass parameters) and +CLI/API validation, instead of scattering `if edge` checks. + +--- + +## 4. Suggested build order + +1. Extract `simplyblock_lib` (tasks core + runner base, monitor bases, v2 API scaffolding, + events, settings) — pure refactor, hyperscale behavior unchanged, immediately reduces + the 17-runner drift. +2.

From b41aa10cd8e5df531a86bc749c5a7897b8f962a9 Mon Sep 17 00:00:00 2001 From: michael Date: Fri, 7 Aug 2026 10:38:15 +0200 Subject: [PATCH 02/14] =?UTF-8?q?Edge=20clusters:=20specification=20+=20im?= =?UTF-8?q?plementation=20(spec=20=C2=A71-=C2=A78)?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit docs/edge_clusters_spec.md defines the v1 design; new simplyblock_edge package implements it on the step-1 library bases: - Tenancy: an edge cluster IS a Cluster record (cluster_type=edge, default hyperscale keeps old records unchanged) — cluster-secret auth, the /clusters/{id} tenancy shape and the task/event keyspace reuse for free. Per-edge k8s access (api url / SA token / CA / namespace) lives on the Cluster record; empty url = the CP's own cluster. - Models: EdgeNode (BaseNodeObject statuses, partitions, is_primary, lvstore_base), EdgeVolume — all keyed {cluster_id}/{uuid} so every read is a bounded range read. - stack.py: pure deterministic bdev planner — local stack per Michael's rule (1 partition = aio, 2 = raid1, 3+ = raid5f), cross-node raid1 mirror with an nvme-tcp leg to the peer's replication subsystem, lvstore on the mirror (2 nodes) or the local top (1 node). aio names keyed by original partition slot so reassembly/replace stay stable. - edge_cluster_ops.py: create cluster, add node (max 2; lazy lvstore; 1->2 expansion under an existing lvstore explicitly rejected per spec §10), volume create/delete/resize/connect, admin shutdown/restart, device replace/add, and the three task handlers (node reassembly with raid re-add + volume republish, raid member replace, raid5 grow). - status.py: pure node-status derivation (unreachable = mgmt-plane verdict, never destructive; returned nodes need a reassembly task before ONLINE; DOWN is admin intent and never auto-restarted) and Michael's cluster rule verbatim (all-out = suspended, partial = degraded, else active). - services: EdgeMonitor (PollingService; bounded k8s+RPC probes, per-cluster isolation) and EdgeTaskRunner (TaskRunner over the three FN_EDGE_* families with host lease + backoff); swarm compose entries. - k8s.py + edge_spdk_pod.yaml.j2: per-cluster kubernetes clients from stored credentials; 2-vCPU hostNetwork SPDK pod rendered and deployed by the CP — no snode agent, no init Job, no vfio (partitions via AIO). - API: /clusters/{id}/edge-nodes + /edge-volumes v2 routers (DTOs local to the module), mounted in the cluster tree. Tests: 76 unit tests (pure planner/status matrices; ops, monitor, task handlers and API routers against a stateful FakeSpdk + FakeEdgeK8s + FakeKV with fresh-read CAS semantics; fakes shared via tests/_mocks.py) plus FDB integration tests incl. a full lifecycle: create -> 2 nodes -> volume -> secondary outage -> degraded -> restart task -> reassembly -> active. Unit tier: 1270 green; ruff/mypy clean. Deferred per spec §10: raid5f rebuild/grow capability check in the fork, takeover/failback, CSI integration, CLI command group, operator CRD.

From 91371f9251cb7ac65ea4bc24b7a7be60410f14a1 Mon Sep 17 00:00:00 2001 From: michael Date: Fri, 7 Aug 2026 21:06:01 +0200 Subject: [PATCH 03/14] Edge clusters v2: fail-over/fail-back, crypto volumes, device lifecycle + e2e suite Spec corrections (docs/edge_clusters_spec.md v2): volumes are dynamic lvols over the lvstore between the nvmf target and the mirror; lvstore fail-over to the secondary and fail-back on primary restart are in scope; optional crypto bdevs keyed from the existing KMS. Core: - Active/passive client paths: every volume's subsystem + listener exists on BOTH nodes from create; only the lvstore host publishes the namespace, so a takeover activates the pre-connected second path via namespace-attach (no ANA). Connect info returns all paths, active first. - Fail-over (FN_EDGE_FAILOVER, monitor-enqueued when the lvstore host stops serving with an ONLINE peer): superblocked mirror reassembles degraded on the secondary via bdev_examine (explicit-create fallback, fork gate), volumes republished actively, lvstore_base flips. - Fail-back inside the returning primary's restart task: wait mirror resync, withdraw namespaces + release the raid on the secondary, assemble + reload on the primary, republish (active there / passive on the secondary). - Crypto volumes: create_volume(crypto=True) inserts a crypto bdev between lvol and fabric; AES_XTS keys from the cluster KMS (Vault or LocalKMS, hyperscale-identical handling), re-registered at every republish; DEKs deleted with the volume. - Device lifecycle for the e2e plan: graceful remove_device/restart_device ops + API, partition offline/unavailable statuses, monitor-side detection of lost backing devices (EBS force-detach -> unavailable, IO continues on raid redundancy). - POST /clusters/edge create endpoint (201 returns the cluster secret); hosts_lvstore on the node DTO; SPDK pod CPU env-overridable (default 1 vCPU for 4-vCPU edge hosts). e2e (e2e/edge/): AWS deployment infrastructure + staged suite per the test plan - boto3 provisioning (VPC, central k3s CP+3-worker cluster, 8 edge k3s clusters covering the 1/2/2p/4-drive matrix on 1- and 2-node variants, cloud-init k3s, tag-swept teardown), deploy.py (CP bootstrap hook, sgdisk partitioning, SA-token minting, API-driven cluster/node/volume creation = test 1), fio pod workload (2 jobs, iodepth 2, 10G, rwmix 30/70, max_latency=20s as the interruption detector, connects all paths), and tests 2-6: parallel fio, single/two-node reboot failovers (incl. lvstore fail-over/fail-back assertions and second-node repeat), device remove/ restart, EBS force-detach error + reattach + permanent replacement, and flaky/broken CP<->edge links (tc/iptables) with mandatory IO continuity. Tests: 105 edge unit tests green (failover/failback, crypto with LocalKMS against the kv fake, device lifecycle); unit tier 1288 green; ruff clean; mypy clean for touched files.

charset=UTF-8 Content-Transfer-Encoding: 8bit Per Michael's clarification, fail-over/fail-back now uses the spdk-fork machinery instead of the cold-standby design, and 2-node clusters run ACTIVE/ACTIVE: - Each node OWNS a store (lvstore over a superblocked raid1 mirror whose legs are bdev_split halves of both nodes' local stacks) and runs a live SECONDARY instance of the peer's store (bdev_lvol_set_lvs_opts roles). - Volume creations run on the store leader and are REGISTERED on the pairing node's secondary instance (bdev_lvol_register) — the lvol bdev exists on both nodes, enabling TWO REAL PATHS per lvol: ANA optimized on the leader, non-optimized on the peer (listeners_create ana_state + nvmf_subsystem_listener_set_ana_state). Placement balances across stores; per-store client ports (4420/4421) bound fail-back fencing. - Fail-over = product flow: bdev_lvol_update_lvstore (refresh in-memory metadata) -> bdev_lvol_set_leader -> ANA flip. Monitor enqueues per-store FN_EDGE_FAILOVER; DOWN owners still fail over (availability wins). - Fail-back on node restart: legs re-added into the survivor's two raid instances, resync gate, then nvmf_port_block on the store's client port, set_leader(False, bs_nonleadership) on the peer, update + set_leader on the returning node, ANA flip, unblock. Restart-without-takeover resumes own leadership. Crypto bdevs exist on both nodes (keys re-fetched from the KMS at every republish). - Deploy-time SPDK vCPU choice 1-6 (API spdk_cpus): 1 = all threads on one core; 2 = app+lvs / nvmf; 3 = one core each; 4-6 add nvmf poller cores. Masks travel as pod env; lvs poller group placed via bdev_lvol_create_poller_group. The central clusters' CPU-topology node-preparation Job (storage_cpu_topology.yaml.j2) now also runs on every edge node before the SPDK pod deploys. Spec §4-5 rewritten for the adopted model; e2e suite updated (leader_of based fail-over/fail-back assertions, spdk_cpus knob, all-path connects). Unit tier 1294 green (100 edge tests incl. promotion, port-fenced fail-back, registration, ANA, cpu-layout matrix); ruff/mypy clean. Fork gates (spec §10): superblock examine-assembly of the mirror on the secondary, update_lvstore semantics over a raid1 leg mid-rebuild, rebuild- progress fields, raid5f rebuild/grow.

The suite could not be COLLECTED: e2e/__init__.py imports the legacy e2e_tests framework at package-import time, so every module beneath e2e/ fails to import outside that environment. Moved the campaign to a top-level package edge_e2e/ (25 cases now collect). 2. Test 2's CENTRAL leg was a silent no-op: deploy.py never created a hyperscale pool/volume and never set state.central.fio_connect, which the test reads. deploy.py now creates pool + volume via sbctl and records the parsed connect info, so fio really runs on the central cluster in parallel with the eight edge clusters. 3. Nothing tied the stages together. Added run_all.py: provision -> deploy (test 1) -> tests 2-6, with --soak-cycles N for unattended fault soaks, --only for subsets, --skip-provision/--skip-deploy/--keep/--teardown-only, a per-run directory (stage logs, junit xml, pre/post cluster-status snapshots, on-failure cluster log capture), and non-zero exit for CI. Also: main's new repo-wide 30s per-test budget would have killed every campaign case, so the tier sets its own (3h) in conftest.py the way the migration tier does, tags cases with a registered edge_e2e marker, and norecursedirs keeps the campaign out of the unit/integration tiers.

Instances came up bare. - `python edge_e2e/provision.py` put edge_e2e/ on sys.path instead of the repo root, so the absolute package imports failed. Added a repo-root bootstrap so both script and -m invocation work. Adds repair_bootstrap.py, which replays the corrected bootstrap over SSH from state.json (idempotent, parallel across agents) so a fleet that lost its one-shot cloud-init can be recovered without re-provisioning. Also adds EDGE_E2E_CLUSTERS to topology.py to run a named subset of the matrix — the cheap 2-cluster validation run before the full fleet.

The scripts live in the PUBLIC simplyblock-io/simplyBlockDeploy under bare-metal/ — the same source .github/workflows/e2e-bootstrap-k8s.yml and k8s-e2e.yaml use. (Lesson: when a doc names a script without a source, grep the workflows.) - bootstrap-cluster.sh takes its topology from ENVIRONMENT VARIABLES (MNODES, STORAGE_PRIVATE_IPS, KEY, BASTION_IP), not CLI inventory; run without them it prints "mgmt_private_ips:" empty and does nothing. The geometry flags had also moved on from the older workflow I copied (--max-lvol -> --max-subsys, --distr-ndcs -> --data-chunks-per-stripe), so the script rejected the command line outright. - sbctl is not on the base image; deploy.py assumed it. Install it (with pip) before reading cluster id/secret.

First: a kubernetes-only deployment has no business installing docker — I had been bending the fleet to satisfy simplyBlockDeploy's bare-metal bootstrap-cluster.sh (root SSH, bastion ProxyCommand, hardcoded key path, docker daemon), fixing each mismatch it produced instead of questioning the script. Second: the operator does NOT own the deployment — it sits ON TOP of the control plane and consumes its APIs, so edge stays an API-tier feature (a future EdgeCluster CR will consume POST /clusters/edge, exactly as StorageNode CRs consume the storage-node APIs today). bootstrap_central() now: - installs helm, then `helm upgrade --install simplyblock-operator` from the official chart (control plane + operator + cert-manager + CSI), - waits for the ControlPlane CR to report status.phase=Ready, - declares the central hyperscale cluster as StorageCluster + per-worker StorageNode CRs, - reads the backend cluster UUID from StorageCluster.status.uuid and the secret via sbctl, for the API-driven edge flow that follows. Deletes the entire bare-metal adaptation: prepare_bootstrap_ssh(), ENABLE_ROOT_SSH, the key copy, BASTION_IP plumbing and the simplyBlockDeploy clone. Charts/operator/CSI live in github.com/simplyblock/simplyblock-operator (the standalone helm-charts repo is deprecated); note the org is `simplyblock`, not the `simplyblock-io` in the stale e2e-bootstrap-k8s.yml.

Root volume is now explicit and sized (EDGE_E2E_ROOT_DISK_GB, default 80), resolved from the AMI's own RootDeviceName and applied to every launch. - create_subnet without an AvailabilityZone let AWS pick us-east-1e, which does not offer m5.xlarge, so RunInstances failed "Unsupported ... in your requested Availability Zone". The AZ is now chosen as one that offers EVERY instance type the run needs (intersection over describe_instance_type_offerings). Verified on the rebuilt fleet: cloud-init completes unattended, all three k3s clusters form, and / has 75 GiB free.

But every push to any branch is already built and published by .github/workflows/docker-image.yml as simplyblock/simplyblock: and public.ecr.aws/simply-block/simplyblock:-; scripts/setup_lblk_* pin exactly that (SB_TAG/SB_IMAGE/SIMPLY_BLOCK_DOCKER_IMAGE). So there was never an image to build — only one to select. deploy.py now derives - from the checked-out commit (EDGE_E2E_SB_IMAGE / EDGE_E2E_BRANCH override it), passes it to helm as --set image.repository/image.tag, and installs sbctl from the same branch with pip git+... the way the soak scripts do. Also: the management API is a ClusterIP service (simplyblock-webappapi:5000) with no ingress, so nothing ever listened on port 80 of the mgmt node. It is now patched to NodePort, the port is read back into state.api_url, and the security group opens the NodePort range.

The failure reason was thrown away. add_edge_node flipped the record to offline and re-raised into a detached API thread whose logger produced no output in the pod, so WHY existed nowhere — not the logs, not the record, not the API response. EdgeNode now carries status_reason, set on the failure path and cleared when the node comes online, and the v2 node DTO exposes it. edge_e2e.wait_node_status aborts as soon as a reason appears instead of burning the whole timeout. 2. A failed add was UNRETRYABLE. The record left behind counted toward MAX_EDGE_NODES, so a 1-node cluster with two failed attempts rejected every retry with "Edge clusters support at most 2 nodes" and could not recover without manual DB surgery. Records for the same hostname that never came online are now treated as the same node: they are dropped and retried into, and they do not count against the limit. Nodes that did come online still cap at MAX_EDGE_NODES and still reject a duplicate hostname. Tests: 103 edge unit tests (3 new — retry after repeated failure, reason recorded, cap still enforced); unit tier 1205 green; ruff clean.
