Why

Once web-2 is told to start the app, a Move is committed. The docs and DESIGN.md promise it finishes on web-2. Only the Move's own row recorded that. When the release that finishes it failed too, for example because the old Server was silent, that row ended, nothing was owed any more, and the next ployz volume release data planned a plain undo back to web-1.

Whether that undo ended on web-1 or web-2 depended on a race nobody can see, whether web-2's promotion landed before the failure. Writes web-2 took in between could be lost, and the undo cost a second stop, sync and start.

A forward release also refused outright when one member Server was briefly silent, so the user had to retry by hand.

What changed

A committed Move stays owed after its run ends. The newest meaningful row by gen decides, defined once in volume-run.server.ts. A committed move or release that has not ended done is pending. A release or move that ends done, or a restore that takes an epoch, settles it.
ployz volume release data on an owed Volume goes forward. The preview reads {direction: "forward", to: web-2, remove_containers_on: [...]}, and the plan pins it, so admission refuses a plan that no longer matches. One pure planner, planForwardRelease, serves the preview and the run. It is ready when every member answers and web-2 holds a copy with a snapshot, waits while a member is silent, and is blocked otherwise.
The release waits for a silent Server instead of refusing. It checks 8 times over 15 minutes and shows "waiting for web-1 to answer (check 1 of 8)", or "waiting for the Servers to answer" when Cloud can't read the Servers. If the Server stays silent the run fails with "web-1 did not answer for 15m; data still finishes on web-2; ployz volume release data tries again", and the row stays committed. Only a timeout or a transport failure waits. RuntimeConnectionFailure gains a waitable field for this, and every other caller still catches by class.
While owed, a move, a mirror, a full sync, a seed, and removing the mirror on web-2 or every mirror refuse with "data finishes on web-2; ployz volume release data finishes it now". Admission protects by Machine id from the plan's own observation and does no Cluster I/O, so a rename cannot slip past it. While Cloud cannot read the Servers, mirror rm refuses until it can. When the release would be blocked, mirror rm refuses with the release's own message, so both name the same cuts to remove.
A Deploy follows an owed Move. It starts the app on web-2 even after the Move's run failed, then requests the release that finishes it. That release carries follows: web-2 and refuses with reason follow_settled if something else settled the Volume first, which the Deploy treats as done. A release still starting web-2 fails the Deploy with "data is finishing its move on web-2; Deploy again".
Removing web-2 ends what is owed there. Machine removal ends every commitment to web-2 under one predicate, active or ended, and repeats until one read finds none. An active one ends failed and names the copy to restore from. An ended one has current cleared, one Volume per statement, so a Deploy holding one Volume's commitment while it reaches for the next is never deadlocked.
The Copies tab hides move and mirror targets while the Volume is owed, since the run's planner would refuse them.
docs/user/services/move-a-volume.md and DESIGN.md describe the owed state, the forward release, the waits and every refusal.

Scope

Items 4 and 7 of the release-lane follow-ups: #1725 c4265573166 and C4 4265571668. The Deploy follow, the Machine-removal clearing and the mirror rm guard came out of review. Each closes a path where the owed state could block a user forever or let a copy that holds the only data be deleted.

Tradeoffs

Every member must answer before the release goes forward, even a Server that holds nothing. web-2 starts from the old Server's stopped Container, and the planner cannot know which silent Server is that one without asking it. A dead old Server must be forgotten with ployz server forget <s> --confirm dead. Its stopped Container goes with it, so the release then fails and the user restores from the new Server's copy with ployz volume restore data --from web-2.

The owed state lives in existing volume_run columns. There is no new table, index or migration, and old rows need no decoder.

Restore stays open while owed, except while a release waits for a silent Server. It is the user's way out when web-2 cannot finish.

Blast Radius

Only Volumes whose Move failed after web-2 was told to start change behavior. On those, release goes forward instead of back, five run kinds and two mirror rm forms are refused until it finishes, and a Deploy starts the app on web-2. Machine removal gains a loop over the commitments to the removed Server. Every other Volume and run plans exactly as before.

Verification

Proven on Boat with three Machines running the stack's top before its rebase onto main, which includes this branch. The commits after it change one message, its test and the user page, and restore one import the rebase onto main needed. A Postgres service db used Volume data with one row in a table.

A failed release resumes forward. A verify fault held a Move of data from machine-1 onto machine-2 at its promotion. Once it committed, machine-2 was powered off. The Move failed, and its release showed waiting for machine-2 to answer (check 1 of 8) through check 8 of 8. It then failed with machine-2 did not answer for 15m; data still finishes on machine-2; ployz volume release data tries again. With nothing running, a move and a mirror were refused with data finishes on machine-2; ployz volume release data finishes it now, and a plain volume sync printed machine-2 isn't answering. After machine-2 was powered on, ployz volume release data ended done 11 seconds later. machine-2 became the writer and ran db, machine-1's container was gone, and the row survived. On main that release plans an undo back to machine-1. A second release ended done and changed nothing, and a move was no longer refused as owed.

Refusals while it waits. During the wait, a move, a mirror, mirror rm and a restore were refused with VolumeBusy: data is starting on machine-2; it finishes there.

A Deploy follows the owed Server. A second run held a Move onto machine-2 and powered off the old Server, machine-1, after machine-2 was told to start. The Move failed removing machine-1's container, and its release waited the full 15 minutes and failed. Deploys while the Move ran, while the release waited, and after it failed each exited 3 for machine-1's missing observation, in 77 to 86 seconds. db stayed on machine-2 with its row throughout. The last requested a release, which ended done 16 seconds after machine-1 came back. Deploys with every Server up took 22 to 28 seconds.

A waiting release finishes when the old Server comes back. A third run held a Move of data from machine-2 onto machine-3 at its promotion and powered off machine-2 once it committed. The Move failed removing machine-2's container. Its release showed waiting for machine-2 to answer (check 1 of 8) through check 6. During the wait, restores from machine-3 and machine-1 and a move to machine-1 were refused with VolumeBusy: data is starting on machine-3; it finishes there. machine-2 was powered on after three minutes, and the release ended done on machine-3 at its next check with both rows. A deploy then ran db on machine-3 and no run was left open.

Forgetting a dead old Server while a release waits for it was not run on Boat. The page describes that path from the code.

Every run ended with verify-cluster down exit 0.

📝 Summary

Summary by CodeRabbit

New Features
- Volume moves remain outstanding after the destination is told to start the service, even if the original run fails. A later deploy can follow the move and request completion.
- Move completion can wait for temporarily unreachable servers and retry for up to 15 minutes.
Bug Fixes
- Moves, mirrors, syncs, and seeds are refused while a committed move still needs finishing. Failover actions are also unavailable while completion is owed.
- Failed releases do not change which server owns the volume. Removing the destination clears its ended commitment.
Documentation
- Updated the move guide with deploy behavior, completion requirements, and recovery steps, including guidance for silent or removed servers.

Volume runs now track unfinished Move commitments and plan Releases toward committed destinations. Conflicting operations are refused while a finish is owed. Deploys can follow ended commitments and request Releases. Placement and the Copies view account for owed status.

No actionable issue is established at the reviewed head; the PR is mergeable after normal checks.

Security architecture risk: 🔵 Low · up to ab0fb

The change preserves the committed destination and existing access restrictions. No concrete new security weakness was established, but interruption, recovery, and upgrades remain important risks because completion now spans multiple releases and deployments.

Retained concerns No architecture-level concerns identified.

Security review details

Security Blast Radius

inferred — The sensitive outcomes are writer promotion and stopped-service-container removal for a resolved Volume, with automatic recovery extending those actions to owed Volumes followed by a Deploy. The inspected paths use organization-scoped authorization and runtime sessions; they do not establish new cross-organization authority.

Trust Boundaries and Controls

observed — Client resource identifiers and placement choices remain subject to server-side access checks and Volume resolution. UI eligibility filtering is advisory. Release planning and admission independently bind the operation to the current commitment, while Deploy fencing rejects unrelated decisions and accepts only compatible destination-and-epoch successors.

Resilience and Maintainability Implications

observed — Recovery separates durable obligations from temporary Deploy holds. Deterministic follow-up Release IDs support repeated execution, completion cleanup drops holds transactionally, and stale-run closure retains unresolved committed destinations for later recovery rather than silently reverting ownership.

_{_{P1 Badge}} Hold owed volumes while the deploy follows them

When an owed volume is not among this deployment's targets, this appends a follow lane without creating a deploy hold for the volume. Because restores are deliberately admitted while a commitment is owed, a restore can claim the otherwise-free lane after placeDeployVolumes returns—even after fenceFollowed has promoted/started the destination—and switch the writer while run-deployment is using that destination; the subsequent release merely observes that the commitment was settled. Acquire and retain a deploy hold for every ended commitment being followed, not only targeted volumes, until finish-volumes releases it.

Useful? React with 👍 / 👎.

NNick28d ago

Fixed in 78feec0f8. One part of the claim doesn't hold. A Volume outside targets is mounted by none of this Deploy's Services, so run-deployment never uses its destination. The race before the fence was real, though. A restore or release admitted between place and fence ended the commitment, and the fence then failed with "changed since". Place now gives each owed Volume it follows that no run holds a deploy hold in the same transaction. A restore or release is refused with "data is deploying; the Deploy ends its run" until finish-volumes drops the hold. A retry sees its own hold and still follows. The new test fails with the hold line removed.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Apply the owed restriction to the failover action.

When the old primary stops answering during an owed Move, failover(observed, row) can still show Use mirror. That button calls edit({ kind: "move", ... }), even though placementTargets(..., owed) removes all move targets and the run refuses moves until release finishes. Hide or disable Use mirror while owed is true.

Fixed in f7178f073. Use mirror renders only when !owed, matching placementTargets. A new component test shows the action while the Primary is silent and hides it once a committed Move is owed.

CcoderabbitaiBot28d ago

@nick-potts The !owed guard addresses this finding and preserves Use mirror when no committed Move is owed. Thanks for adding the component test.

Do not return the raw owed row in the operation result.

admitRun returns { ok: false, refusal, busy, owed } on refusal. owed is a full VolumeRunRow, which includes organizationId, requestedByUserId, inngestRunId and other internal columns. runVolume passes the refusal object through unchanged, so admitOperation gets the row as part of the operation result. The old insertRun result carried only refusal and busy. Map the refusal to the public shape before you return it.

NNick28d ago

Fixed in f7178f073. runVolume now maps a refusal to { ok: false, refusal, busy }, so the owed row stays inside the server. The clients only ever projected refusal, so nothing leaked to a user, but the operation result no longer carries internal columns.

CcoderabbitaiBot28d ago

@nick-potts Thanks for the clarification. The updated runVolume mapping keeps owed out of the operation result. My concern was about internal result propagation, not an established user-facing data leak.

An internal `owed` row in the operation result does not by itself establish that internal columns reach users; verify downstream client projections before claiming user-facing exposure.

_{_{P2 Badge}} Admit followed releases before dropping deploy holds

When a Deploy targets an owed Volume, finish-volumes removes its hold before release-followed admits the cleanup release. A concurrent allowed operation such as removing a non-target mirror can claim the lane in this gap; the release is then refused because mirror removal keeps its lane, and releaseFollowed only logs the refusal without retrying. The successful Deploy therefore leaves the commitment owed and requires a later manual release, so admit the release atomically with finishing the hold or retain the hold until admission completes.

Useful? React with 👍 / 👎.

NNick28d ago

Fixed in f7178f073. release-followed now runs before finish-volumes. For each followed Volume, it drops the Deploy's hold and its heldBy stamps and admits the release in one transaction, so no mirror removal can claim the lane between them. finish-volumes still drops every remaining hold afterwards. Two new postgres tests cover it. One asks a mirror removal right after the release and sees it wait on the release. The other has a stamped beside lane and sees the release admitted with no stamp left. Both fail with the per-Volume dropHolds line removed. A beside lane still running at that moment still refuses the release and leaves the commitment owed with a logged warning. That residual goes to the follow-up issue.

_{_{P2 Badge}} Fail closed while the owed-state read is unavailable

When this new query is still loading or has failed, coercing undefined to false makes the Copies panel temporarily offer Add copy and Make primary even though the Volume may still owe a committed Move. This is observable when the other panel queries are cached or the owed request errors: the click persists a placement change, and the subsequent Deploy fails when server-side admission rejects that move or mirror. Treat an unresolved owed state as locked, or withhold these actions until the query succeeds.

Fixed in f7178f073. The panel reads useVolumeOwed(...).data ?? true, so while the owed state is loading or failed, Add copy, Make primary and Use mirror stay hidden.

_{_{P2 Badge}} Gate the failover action while a move is owed

When a committed Move is owed and the presumed primary is silent, failover() can still return an answering mirror. Passing owed only to placementTargets hides Add copy and Make primary, but the Use mirror action below checks only accepting, so clicking it stages another move that admitOwed will necessarily reject during the next Deploy. Suppress or disable this failover action while owed is true.

Drop the trigger even when the test fails before releaseLanesOff runs.
The try/finally starts after the trigger is created. That part is correct. The problem is the create function call: it sends two statements in one query. If the trigger statement fails, the function admit_after_clear stays in the schema. Every later test run then fails with "function already exists". This test also ships a persistent trigger on the shared volume_run table. If the harness reuses the database across tests, a failure inside the finally (for example, a dropped connection) leaves the trigger active and corrupts later tests. Use create or replace function and drop trigger if exists ... ; drop function if exists ... to make setup and cleanup idempotent.
The static-analysis SQL-injection hint is a false positive. release.id is a server-generated UUID in a test.

@nick-potts The updated paragraph addresses the finding. It now distinguishes Release behavior before and after web-2 is told to start the service.

_{_{P2 Badge}} Prevent removing the destination while a move is owed

When an owed move's destination is displayed as a configured mirror, owed suppresses Make primary here but remove is still built from offered, so Remove mirror remains available. Clicking it stages deletion of the copy that must finish the move; the next Deploy reaches refusedWhileOwed, fails, and leaves the user with a staged change that cannot apply until the release finishes. Gate this destructive action for the owed destination as well (or conservatively while only the boolean owed state is available).

Not fixing in this PR; tracked in the release-lanes follow-up issue. Nothing is lost here. Admission refuses a delete_mirror of the copy the owed Move finishes on (refusedWhileOwed, volume-run.server.ts:244-248, keyed by Machine id), so the next Deploy fails with " finishes on ; ployz volume release finishes it now", and the staged removal can be discarded in Details. On main the same click deletes that copy, so this PR turns a data loss into a refusal. Hiding the button needs the owed Machine id on the client, which useVolumeOwed returns only as a boolean today; hiding every Remove mirror while owed would also block removing the other mirrors, which admission allows.
