Let the app run on more than one node - #399
Conversation
Tests first, committed red. Each one fails against the current code for a
reason worth naming:
- test_parameter_integrity: a failed params.json read currently returns {},
which save_parameters merges and writes back, erasing _defaults,
_flag_params and every other tool's values while telling the user it was a
deliberate reset.
- test_tasks: tasks.py logs WORKFLOW FINISHED unconditionally and returns a
dict from its exception handler, so RQ records every job successful and
FailedJobRegistry is structurally empty. This module had no coverage at all.
- test_seed_demos: the seed-demos initContainer uses `cp -rn`, which under
replicas: 2 either skips a file another pod is still writing, permanently,
or exits 1 on EEXIST into Init:CrashLoopBackOff.
- test_storage_health / test_sidebar_monitors: for a storage indicator that
must read Redis only. A stat on a hard NFS mount blocks in uninterruptible
sleep, so a widget that touches the filesystem becomes the hang it reports.
docker/seed-demos.sh is extracted so the manifest and the test share one copy
rather than drifting. .gitattributes pins *.sh to LF: a CRLF checkout breaks
both sh in the container and the test.
test_topp_flag_parameters keeps its argv assertions unchanged; only the
fixture is hardened, because thread resolution is about to depend on a
settings.json read relative to the working directory.

Nothing downstream can be validated while every failure reports as success,
so this lands first.
The success signal was inverted in both directions at once. Locally,
Workflow.execution() was annotated -> None and returned nothing, so the
WORKFLOW FINISHED marker was never logged and a successful run rendered
"Errors occurred". In queue mode tasks.py logged that marker unconditionally
and returned a dict from its exception handler, so RQ recorded every crash as
a success and health.py's failed_jobs was structurally always zero. Both are
fixed together: honouring the bool while execution() still returned None
would have made every workflow report failed.
execution() now also gates on each run_topp/run_python result. Those already
returned False on a non-zero exit and nobody looked, which is why a tool that
died mid-run still reported success. A subclass still declaring -> None keeps
working, with a deprecation warning in the workflow log.
params.json reads are split rather than flagged. get_parameters_from_json
stays tolerant for the two constructors and five read-only callers, but no
longer launders a read failure into {} silently, and its st.error is now
conditional on a real session — tasks.py builds a ParameterManager in the RQ
worker where it was a silent no-op. The read-modify-write-back sites use a
strict read that raises and aborts the write instead of persisting {}.
StreamlitUI's input_TOPP path gets more than a raise: it runs on every
configure() render, so it preserves the file and offers a reset rather than
dumping a traceback on the parameter page.
max_threads.online has been dead code since PR #333: the worker has no
ScriptRunContext, so st.session_state.get("settings", {}) is {}, the online
branch was unreachable, and it silently used the hardcoded local default of 4.
A Streamlit-free settings loader fixes that, and the result is memoised
because run_topp resolves it twice and both reads must agree.
create-workflow.md documented the broken -> None signature, which would have
regenerated the bug in every new workflow.

Every change here is a no-op or an improvement on the current single-node volume, so it ships before the storage cutover rather than with it. That way the cutover has working instrumentation to be watched with. The seed-demos initContainer no longer uses `cp -rn`. It copies to a private temp directory and renames: rename(2) on a directory is atomic, so the winner renames and the loser cleans up and exits 0. A lock file would be the wrong tool. It also gets a bounded timeout and exits 0 on failure, because it blocks pod start on the mount and would otherwise defeat the decision that the UI survives a storage outage. The storage indicator reads Redis and never the filesystem. A worker with the mount refreshes a per-node key with a TTL, so the TTL is the liveness mechanism and there is no timeout logic to get wrong. Per-node keying matters because a single healthy node would otherwise mask a wedged one. It reports three states, not two: connected, unreachable, and unknown when Redis itself is down — a red indicator caused by a dead Redis sends an operator debugging the wrong layer. monitor_hardware is now hidden in online mode. It reads psutil on the Streamlit pod, which does no work once execution is distributed, and would show an idle web pod while a worker saturates. The cleanup CronJob gets activeDeadlineSeconds. It is concurrencyPolicy: Forbid, so one run hung on a storage restart would block every subsequent night, silently and permanently.

The app could not use more than one node: a ReadWriteOnce Cinder volume attaches to exactly one, and four workloads mount it. This runs NFS-Ganesha over that volume and hands out a ReadWriteMany claim instead. k8s/storage/ is a separate kustomize root rather than a component, because k8s/base sets `namespace: openms` and the namespace transformer runs after patches — it would clobber any per-object namespace, and components inherit the parent's transformers. It is deliberately prefix-free so namePrefix never has to be duplicated into a Helm values file. workspaces-nfs-pvc is a NEW claim, not an edit of workspaces-pvc. A bound PVC's spec is immutable apart from resources.requests, so apply would be rejected outright, and the only way past that is deleting a claim whose cinder-csi class reclaims with Delete — destroying the volume the rollback depends on. The mountPath is unchanged, and every consumer already reaches the volume through claimName plus /workspaces-streamlit-template, so nothing in src/ changes and absolute symlinks and external_files.txt survive untouched. Four Ganesha settings are load-bearing and commented as non-tunable. existingClaim and reclaimPolicy: Retain keep the data across pod and PV lifecycles. strategy: Recreate avoids the deadlock where a new pod cannot mount the claim the old one still holds. device-based-fsids: false is the subtle one: the default derives NFS file handles from the backing device's major/minor, and a Cinder /dev/vdX minor is not stable across re-attach, so every client would ESTALE after the first restart — weeks later, with nothing to link it to the cause. An explicit memory limit is set because N concurrent write streams put N sets of buffers in one userspace process, and OOM there is the one genuine collapse mode in this design. The NetworkPolicy needs two allow rules, not one. Ganesha exports no_root_squash, and the namespace is shared with another application, so a pod-label rule alone is the isolation that matters — but the provisioner emits in-tree nfs: PVs which the kubelet mounts from the node's own address in the host network namespace, matching no podSelector. Without the second rule every mount hangs. It ships as a placeholder that must be narrowed to the real node addresses. CI applied only the prod overlay, so a storage root it never applied would have stranded every pod; it now applies both. The `|| true` on the deployment availability wait is removed — a Pending, CrashLooping or unschedulable Deployment passed silently, leaving the ingress curl as the only real gate.

Removes per-node memory tiering entirely. Nothing in k8s/ now pins a pod to a node — no nodeSelector, no nodeName, no nodeAffinity, no openms.de/memory-tier labels. A tier survives only as a pod size, which is a request the scheduler can act on rather than a label an operator has to maintain. The memory-tier components were already the right shape; they just carried a nodeselector.yaml patch targeting `kind: Deployment` with no name, which landed on redis and streamlit as well as the worker while missing the CronJob entirely. Deleting the patch files and their kustomization entries is atomic: a kustomization referencing a deleted path fails to build. requests now equal limits in both tiers. That is architectural rather than tidy: the pod size is the tier, so a worker requesting 1Gi against a 16Gi limit would be schedulable anywhere and then OOM. Guaranteed QoS also moves oom_score_adj from roughly 937 to -997, so the worker stops being near the top of the node's kill list. rq-worker moves to a fixed replica count with topologySpreadConstraints over kubernetes.io/hostname. Those constraints were inert before: maxSkew is measured over eligible domains, and the nodeSelector left exactly one node eligible, so any spread rule written earlier would have passed while changing nothing. k8s/overlays/ci exists because a production-sized worker cannot be scheduled on a CI runner; it is prod with the worker shrunk, so the kind jobs exercise the real manifests rather than a hand-maintained copy. docs/kubernetes-deployment.md claimed the VolumeBinding plugin pins pods to the node holding the attached volume. It does not — the scheduler checks PV node affinity only, and the result is a Multi-Attach hang at attach time rather than a scheduling refusal. That belief is why the old topology looked intentional. configure-k8s-deployment.md had no question about worker size or replica count at all, and told operators co-location was enforced by the RWO mount. Both are now wrong and both are fixed. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01XFgL1SSeMCM3J1ZuAVTXv7

Derive Q6 from the selected worker-size component.
Line 35 and Line 84 define the Q6 default from the base value of 2. k8s/components/memory-tier-high/worker-resources.yaml overrides that value to 1.
If a user selects memory-tier-high and accepts the stated Q6 default, Step 3 adds no patch. The rendered Deployment then has one worker, although the skill reported two.
Derive the Q6 default and the “add a patch only if different” condition from the effective selected component. For memory-tier-high, the default must be 1.

|
||
| `start_workflow()` flushes params to disk, then dispatches to Redis/RQ if `online_deployment` is true and Redis is reachable, else to a local `multiprocessing.Process`. The container entrypoint starts `redis-server`, N × `rq worker openms-workflows`, and the Streamlit server(s) — all in one image. | ||
|
|
||
| **`src/workflow/tasks.py` runs inside the RQ worker and must stay importable without Streamlit.** It rebuilds the workflow object with `object.__new__(WorkflowClass)` and hand-injects the members, deliberately bypassing `__init__` because that needs Streamlit. So **anything reachable from `execution()` must be session-state free** — the worker has no `st.session_state`. Worker and UI share state only through the workspace filesystem (`params.json`, `logs/`, `pids/`) and RQ job metadata. `REDIS_URL` defaults to `redis://localhost:6379/0`. | ||
|
|
||
| The off-switches are `online_deployment` and unsetting `REDIS_URL`. `docs/REDIS_QUEUE_IMPLEMENTATION_PLAN.md` is a pre-implementation design doc written in future tense — the work shipped, its line references are stale, and the `queue_settings.enabled` flag it describes is read nowhere. Read the code. | ||

Make an absent REDIS_URL disable queue mode.
When online_deployment is true, _check_online_mode() still returns true if REDIS_URL is absent, and QueueManager.REDIS_URL falls back to redis://localhost:6379/0. A reachable local Redis therefore queues the job instead of using the documented off-switch. Align the gate with the documentation and add a regression test for online_deployment: true with REDIS_URL absent.

Count restored directories, and do not swallow a failed mkdir.
restored increments only for files and symlinks. A directory created at line 201 does not increment it, and || true discards a failure. Two consequences follow.
- A run that recreates missing directories declares
outcome=presentand prints "nothing to do", although it repaired the destination. - A run whose
mkdirfails leaves every entry below that directory uncopied and still declaresoutcome=present.
outcome is the only machine-readable signal the callers have, and tests/test_seed_demos.py reads it instead of the prose. Make the directory branch update the counter and report the failure.

Replace the placeholder node CIDR before this storage root is deployable.
Line 159 admits only 192.0.2.0/24, which is non-routable documentation space. Kubelet NFS mounts therefore cannot reach TCP 2049 when the CNI enforces this policy. The workspace pods remain in ContainerCreating, so the application cannot start.

Validate imported params.json before writing and read optional workflow flags defensively. The uploader currently accepts arbitrary JSON, while queue-mode execution indexes mzML-files and run-python-script directly. A malformed or incomplete upload can therefore be rejected by the strict reader or crash the worker with KeyError instead of returning a failed run. Parse the upload as an object, remove reserved keys before saving, and use .get() for these optional flags in src/Workflow.py so invalid input follows the failure contract.

Open the log files with encoding="utf-8" here too.
str(e) and traceback.format_exc() can carry non-ASCII text, for example a file name or tool output. The enclosing open(log_file, "a") uses the platform default encoding. On a non-UTF-8 locale the write either corrupts the text or raises UnicodeEncodeError. The outer except Exception: pass at line 182 then swallows it, so the user loses the error message completely. Every other reader and writer of the workflow files in this PR now pins utf-8.

Every job that renders k8s/storage/ was failing on one thing: azure/setup-helm
was unpinned at four sites and `latest` now resolves to Helm v4.2.4, which
removed the `-c` shorthand that the kustomize inside kubectl uses to probe it.
`kubectl kustomize --enable-helm` refused outright, so assert-invariants died
in its first assertion and all eight kind jobs died before applying a single
manifest - with none of the eleven new assertions ever executing.
Pin helm to v3.21.4 at all four sites, and pin kubectl and kind-action too:
setup-kubectl resolved `latest` from the frozen legacy GCS bucket (v1.31.0,
kustomize 5.4.2) while the kind jobs ran v1.35.0 / 5.7.1, so the static gates
validated output the clusters never saw. Not fixed by bumping kubectl past
1.36 instead: kustomize 5.8.1 stops applying the namespace transformer to
Helm-inflated objects, which would deploy Ganesha outside its NetworkPolicy
for anyone using the documented apply pipe.
Unmasked by that, four gates that could not fail:
- lint-manifests piped a failing kustomize into kubeconform under a shell with
no pipefail, printed `Valid: 0`, and passed in 11s. The chart it exists to
validate had never been validated. Render to a file and require it non-empty
- kubeconform exits 0 on empty input, so pipefail alone would not catch a
render that succeeds and emits nothing.
- The storage apply loop used `if ...; then break; fi`, which never trips
`set -e`, so total failure fell through to a command substitution that killed
the step before the authored error message could run.
- The Traefik host list is derived through `grep -oP | tr`; a miss yields an
empty string with exit 0, and the only curl of the app through Traefik then
iterated zero times, green. Also `--set service.type=ClusterIP` is a dead
values path in that chart - the key is service.spec.type - so the Service had
been LoadBalancer all along.
- assert_workers_spread_across_nodes walked only the selector keys that were
present, so a constraint that lost its app scoping matched the pod template
and passed. That is precisely the regression the base manifest's own comment
calls load-bearing.
Adds two assertions. assert_netpol_admits_every_node checks from the cluster
that every node InternalIP is admitted on 2049, because the node CIDR is
rewritten by CI rather than shipped and a sed whose target moves fails silently
forty minutes later as an unrelated timeout. assert_storage_identity_values
covers the three quarters of invariant 2 that nothing checked - Retain, the
fixed backing claim, the single replica - each of which renders, deploys and
passes every runtime assertion while costing deleted data.
Also rewrites the kind node CIDR (kindnetd enforces NetworkPolicy, and the
kubelet mounts in-tree nfs: PVs from the node address, so the shipped RFC 5737
placeholder hangs every cross-node mount), sizes the CI claims to what the
runner can actually provide, and drops the `-l app=${SLUG}` selectors from the
failure dump - SLUG is exported after the storage steps, so every job that died
early dumped an empty namespace and looked like an empty cluster.

Three corrections that the move to a genuinely shared volume makes matter, kept deliberately narrow - the rest of the review backlog is a follow-up. max_threads now comes from the container's own cgroup CPU quota in online mode, with max_threads.online left as the fallback for deployments that expose none. Reading settings.json instead of session state fixed the worker reading a hardcoded 4, but replaced it with a single static number that cannot describe both a 4 cpu low-tier worker and a 20 cpu high-tier one - and described neither. The worker runs at requests.cpu == limits.cpu, so its pod spec is its allocation. Both cgroup generations are handled, quotas round up (1500m is two useful threads, not one), and "no quota" reports None rather than 1 so a laptop does not silently serialise. The trade-off is deliberate and user-visible: an operator can no longer under-subscribe a container that declares more CPU than it wants used. _write_parameter_file keyed its scratch file on os.getpid() alone. Streamlit serves every session from threads of one process, and that process is pid 1 in every replica, so two sessions sharing a ?workspace= link - or two pods, now that the volume really is ReadWriteMany - resolved to the same path and interleaved into it, publishing exactly the torn file the function exists to prevent. Adds a uuid, plus flush+fsync before the rename, since os.replace orders the directory entry and not the data behind it. allowVolumeExpansion was the one storageClass key still inherited in a values file that restates its defaults on purpose. The chart defaults it true and an in-tree nfs: PV has no expander, so a resize is accepted and then sits in FileSystemResizePending forever. The existing max_threads tests pin detect_cpu_quota to None explicitly rather than trusting the runner to be unconstrained, and reach it through the function's own globals - the module-globals idiom this file already uses, because src.workflow.* is popped from sys.modules and a dotted-name patch would target a second copy of the module.

Linux cgroup v1 cpu,cpuacct combined controller mount path /sys/fs/cgroup/cpu,cpuacct
💡 Result:
In Linux cgroup v1, the cpu and cpuacct controllers are frequently mounted together against a single hierarchy at /sys/fs/cgroup/cpu,cpuacct [1][2][3]. The mount path /sys/fs/cgroup/cpu,cpuacct is a convention used to signify that both the cpu (which manages CPU scheduling/bandwidth) and cpuacct (which tracks CPU usage statistics) subsystems are active within that specific cgroup hierarchy [1][4]. Key technical points regarding this configuration: 1. Comounting: It is possible in cgroup v1 to mount multiple controllers against the same hierarchy [1][5]. Comounting these two specific controllers ensures that the resource management (via cpu) and resource accounting (via cpuacct) apply to the exact same group of processes [2][6]. 2. Standard Practice: While administrators can choose custom mount points, many systems—particularly those managed by init systems like systemd—automatically manage these mounts under the /sys/fs/cgroup directory [1][3][6]. 3. Relationship: Although historically distinct, the functionality of the cpuacct controller was integrated into the cpu controller's interface in later kernel versions to streamline management [7][8]. Despite this, the convention of co-mounting them often persists for compatibility with tools and scripts that expect both to be present [7]. To mount these controllers manually at this path, one would typically use: mount -t cgroup -o cpu,cpuacct none /sys/fs/cgroup/cpu,cpuacct [1][2]

The problem
The app cannot use more than one Kubernetes node.
k8s/base/workspace-pvc.yamlisReadWriteOnceoncinder-csi, and a Cinder volume attaches to exactly one node — four workloads mount it. Compounding that, bothmemory-tier-*components patchednodeselector.yamlattarget: {kind: Deployment}with no name, so streamlit, rq-worker and redis were pinned to whichever node carried the tier label.On a two-node cluster that means the second node hosts nothing. This makes it usable, on a design that still works as the cluster grows.
Two invariants
1. Kubernetes decides placement; the config does not. No
