* fix(obs): open cleaner compression source with O_NOFOLLOW The compressor opened the source log via File::open, which follows a symlink at the final path component. Between the scanner selecting a regular file and this open, an attacker with write access to the log directory could swap the entry for a symlink (TOCTOU) pointing at, say, /etc/shadow, whose contents would then be copied into an archive. Open the source with O_NOFOLLOW on Unix so such a swap fails with ELOOP; the temp/archive path already refused symlinks, this closes the source side. Refs rustfs/backlog#1210 Co-Authored-By: heihutu <heihutu@gmail.com> * fix(obs): recompress instead of trusting leftover cleaner archives archive_header_ok only checked the first 2-4 magic bytes before treating an existing .gz/.zst as a completed prior result and letting the caller delete the source log. A file with valid magic but a truncated or forged body passes that check, so an attacker with write access to the log directory (or a crashed prior run) could plant such a stub and make the cleaner delete the real log without ever producing a usable archive — silent audit-data loss. Chosen fix: stop trusting cross-process leftovers entirely and always recompress the source in this pass, rather than fully decoding every leftover to validate it. Full-decode validation would add real CPU cost and decode-bug surface for a rare crash-recovery case; the existing atomic create_new+rename already overwrites whatever sits at the archive path (a planted symlink is replaced, never followed) with a freshly written, fsync'd archive, so a partial/forged leftover can never gate source deletion. This is the lowest-regression option. Refs rustfs/backlog#1211 Co-Authored-By: heihutu <heihutu@gmail.com> * fix(object-data-cache): cap memory-gate reservation at cache growth headroom The memory gate subtracts `admitted_since_refresh` from the snapshot's available bytes so a burst arriving faster than the 5 s refresh cannot over-allocate. That counter is GROSS: it only rolls over on the refresh and never rolls back when a fill is later evicted, cancelled, or loses the invalidation race. Under sustained high-throughput churn (net footprint flat and far below `max_capacity`) the raw counter balloons past the memory the cache actually holds, so `effective_available` collapses and the gate reports false memory pressure — skipping the hottest fills with SkippedMemoryPressure until the next 5 s refresh. This only lowers hit rate; it never returns wrong data and self-heals each refresh. Fix direction 1 (minimal regression): cap the reservation deduction at the cache's own growth headroom (`max_capacity - weighted_size()`) instead of letting the unbounded gross counter shrink the system-available budget. The cache can never hold more than `max_capacity`, so a burst adds at most that headroom of real memory before moka evicts to stay bounded (net-zero churn beyond that point) — capping the deduction there keeps the reservation honest without treating gross churn as growth. Chosen over net-accounting (direction 2, releasing bytes on every failure/cancel/eviction path) because that only plugs the leak on failed fills and would not address the core defect: churn of *successful* insert/evict fills over the 5 s window. It also touches only the gate plus one call site rather than every failure path in moka_backend. The cap only ever raises `effective_available`, so real memory pressure (a low snapshot at refresh) still suppresses fills; when the cache is at capacity the headroom is 0 and the deduction vanishes, correctly reflecting net-zero churn. `MokaBackend` now stores `max_capacity` and passes the live headroom into `allows_fill`. Adds targeted gate tests: gross churn far above headroom no longer falsely suppresses, yet the reservation still bounds a burst while the cache can genuinely grow. Refs rustfs/backlog#1212 Co-Authored-By: heihutu <heihutu@gmail.com> * test(ecstore): assert native O_DIRECT path runs in uring read test uring_preserves_o_direct_for_eligible_reads only compared bytes through LocalDisk::read_file_mmap_copy. On a filesystem that rejects O_DIRECT the read silently degrades to the buffered StdBackend fallback and the byte check still passes, so the test could go green without the native read_at_direct path ever executing -- a vacuous pass. Add a per-disk native_direct_reads counter on UringBackend, incremented only when pread_uring_direct completes, and rebuild the test to drive a real UringBackend's pread_bytes and assert the counter is non-zero (every eligible read went through the native tier). When io_uring or O_DIRECT is unavailable on the host filesystem (restricted CI runners, tmpfs), the test skips loudly via eprintln instead of asserting a tautology, while still checking byte-correctness on whatever tier served the read. The counter also gives a gray release a positive signal that the O_DIRECT tier is serving reads, not just a fallback count. Refs rustfs/backlog#1213 Co-Authored-By: heihutu <heihutu@gmail.com> * fix(ecstore): warn + count read-time EINVAL on native O_DIRECT reads classify_direct_read_error is only reached from the read side: the O_DIRECT open in pread_uring_direct already succeeded (an open-time refusal is handled earlier as DirectOpenError::ODirectRefused). So an EINVAL/EOPNOTSUPP arriving here is a read-time error on an fd the kernel accepted for O_DIRECT -- far more likely an alignment bug in the aligned read path than an unsupported filesystem. The old code latched the disk's native path off with only a once-per-disk debug trace, hiding a potential correctness regression behind a silent buffered-read downgrade. Diagnostics only: the fallback behaviour is unchanged (the native path is still latched off and the caller still reads via StdBackend). This adds a rustfs_io_uring_direct_read_einval_total counter and promotes the once-per-disk trace from debug to warn so an operator can see an alignment regression instead of an unexplained latency/CPU shift. Refs rustfs/backlog#1214 Co-Authored-By: heihutu <heihutu@gmail.com> * docs(ecstore): document data-blocks-first default and its tail-latency cost DEFAULT_RUSTFS_GET_DATA_BLOCKS_FIRST_READER_SETUP is true and must stay true: deferred-parity is the deliberate, already-rolled-out full-object GET default from backlog#1159/#923. Flipping it back to false in code would silently revert that rollout for every deployment that has not set the env var, so this commit only documents -- no behaviour change. The added notes explain what data-blocks-first does (schedule data shards up front, engage parity lazily on a missing/corrupt data shard), the known trade-off (parity is engaged late, so a slow-but-not-dead data drive raises GET p99 because the faster parity shards are not raced against it until a data shard is declared missing), and the operational rollback switch (RUSTFS_GET_DATA_BLOCKS_FIRST_READER_SETUP=false), which is intentionally an env override rather than a code default change. No metric was added: the low-risk observability hook for "slow data drive engaged deferred parity" would live at the deferred-stripe engage point, which is out of this file's scope; this change stays documentation-only to avoid touching the hot GET path. Refs rustfs/backlog#1215 Co-Authored-By: heihutu <heihutu@gmail.com> * docs(ecstore): document wide-directory walk stall hazard and tuning list_dir enumerates a whole directory in one os::read_dir call (count = -1), and the walk caller bounds that entire enumeration with the per-read stall budget (default 5s) as if it were a single read. For a wide, flat prefix -- one directory holding millions of immediate children -- a single readdir can exceed the budget on a healthy disk, trip DiskError::Timeout, and surface as a ListObjects 500 quorum failure though the drive is fine (a #2999 sub-class). This is documented, not rewritten: turning the one-shot readdir into a streaming/batched enumeration that refreshes the stall deadline between chunks is an architecture-level change with high regression surface (ordering, the count contract, quorum merge) and belongs in a separate follow-up. The supported mitigation today is operational, so the comments point wide-directory deployments at RUSTFS_DRIVE_WALKDIR_STALL_TIMEOUT_SECS and the high-latency drive-timeout profile, which widen the budget with no code change. Notes were added at list_dir, the scan_dir call site, and get_drive_walkdir_stall_timeout. No behaviour change. Refs rustfs/backlog#1216 Co-Authored-By: heihutu <heihutu@gmail.com> * docs(ecstore): document consumer-peek vs producer-stall coupling In list_path_raw the consumer's peek_timeout is drawn from the same source and same value (walkdir_stall_timeout, default 5s) as the producer-side walk stall budget, but the two measure different things: the producer stall bounds a single drive read, while the consumer peek bounds the gap between two ADJACENT entries arriving from a reader. Because they share a value, the consumer cannot wait meaningfully longer for the next entry than the producer is allowed to spend producing one. Walking a region dense with non-listable internal items can make a HEALTHY drive miss the budget between visible entries; the consumer then declares it stalled and detaches it, dropping a good drive from the merge and capping the "large prefix succeeds" guarantee. Documented, not decoupled: giving the consumer peek an independent, strictly-larger budget would cut these false detaches but equally delays detaching a genuinely dead drive and shifts listing tail-latency semantics, so it wants soak data before changing the default. The comment records the invariant any such follow-up must keep -- consumer peek >= producer stall, never stricter -- so it can never fail a drive before the producer would. No behaviour change. Refs rustfs/backlog#1217 Co-Authored-By: heihutu <heihutu@gmail.com> * fix(io-metrics): add time-based trigger for low-IOPS latency percentiles Percentiles were recomputed only every 128 IOs and seeded to 0, so a low-traffic deployment exported p95/p99 = 0/stale for a long time after startup. Add a 10s wall-clock trigger alongside the count throttle so the first recompute can fire before 128 samples accrue. Hot-path per-op mean update is unchanged. Refs rustfs/backlog#1218 Co-Authored-By: heihutu <heihutu@gmail.com> * test(e2e): cover codec-streaming parity under fault injection and NoSuchKey The codec-streaming compat A/B previously ran only against a healthy 4-disk EC set with successful full GETs: the DiskFaultHarness was constructed but never faulted, the error path was untested, and the range assertion silently compared legacy-vs-legacy (ranges always fall back to the duplex path), overstating what it proved. Add two genuinely-failable scenarios reusing the existing harness and fixtures: - Parity reconstruction A/B: take one data disk offline and re-run the full object matrix on both phases while the EC 2+2 set rebuilds each large object from the surviving shards. Assert codec == legacy byte-for-byte (sha256) and header-for-header, and assert the codec phase served the reconstructed objects with zero duplex-pipe fallback (the reader gate is drive-health-independent, so the codec fast path is really exercised through reconstruction). - NoSuchKey negative path: compare the HTTP status + S3 error code of a missing-key GET across the legacy and codec phases and require them to be identical (404/NoSuchKey), guarding against the codec env perturbing the error path. Also clarify the range-phase comment so it is not misread as codec-range correctness coverage: both sides are served by the same legacy range path, so the assertion only proves ranges keep working and keep falling back to legacy with the gates open. Verified: cargo check/--no-run pass and the test passes locally (1 passed; dup_codec=0 confirms the codec path ran). Refs rustfs/backlog#1219 Co-Authored-By: heihutu <heihutu@gmail.com> * ci(ecstore): exercise native O_DIRECT read path on an ext4 loopback The uring-integration leg ran on the runner's default TMPDIR, which may sit on tmpfs/overlayfs where open(O_DIRECT) fails and the native read_at_direct path silently latches off to the aligned StdBackend fallback. Mount a dedicated ext4 loopback and point TMPDIR at it so the real io_uring dep (bumped git->0.1.0->0.2.0->0.2.1) and the native O_DIRECT read path are actually covered rather than validated only by signature diffing.

Quickstart
To get started with RustFS, follow these steps:
1. One-click Installation (Option 1)
curl -O https://rustfs.com/install_rustfs.sh && bash install_rustfs.sh
2. Docker Quick Start (Option 2)
The RustFS container runs as a non-root user rustfs (UID/GID 10001:10001). If you bind-mount host directories with Docker or Compose, every mounted path must be writable by that user, otherwise startup may fail with permission denied errors. This applies to data directories, log directories, and TLS certificate directories when RUSTFS_TLS_PATH is enabled.
# Create data and logs directories
mkdir -p data logs
# Change the owner of these directories
chown -R 10001:10001 data logs
# Using latest version
docker run -d -p 9000:9000 -p 9001:9001 -v $(pwd)/data:/data -v $(pwd)/logs:/logs rustfs/rustfs:latest
# Using specific version
docker run -d -p 9000:9000 -p 9001:9001 -v $(pwd)/data:/data -v $(pwd)/logs:/logs rustfs/rustfs:1.0.0-beta.8
If you use podman instead of docker, you can install the RustFS with the below command
# Create data and logs directories
mkdir -p data logs
# Run the container (podman will automatically set the folders ownership)
podman run -d -p 9000:9000 -p 9001:9001 -v $(pwd)/data:/data:Z,U -v $(pwd)/logs:/logs:Z,U rustfs/rustfs:latest
If you enable TLS with a bind-mounted certificate directory, prepare that mount the same way:
mkdir -p certs
chown -R 10001:10001 certs
You can also use Docker Compose. Using the docker-compose-simple.yml file in the root directory:
docker compose -f docker-compose-simple.yml up -d
Before running Compose with host bind mounts:
- Ensure every mounted host path is writable by
10001:10001. - If you enable TLS, ensure the certificate mount for
/opt/tlsis also readable by10001:10001. - If matching host ownership is not practical, run the
rustfsservice withuser: "<host-uid>:<host-gid>"instead. docker-compose-simple.ymlincludes avolume-permission-helperservice for named volumes.docker-compose-simple.ymlrelies on you to prepare bind-mounted host paths in advance.
Similarly, you can run the command with podman
podman compose -f docker-compose-simple.yml up -d
Webhook notification quick start (Docker):
docker run -d --name rustfs -p 9000:9000 \
-e RUSTFS_NOTIFY_ENABLE=true \
-e RUSTFS_NOTIFY_WEBHOOK_ENABLE_PRIMARY=on \
-e RUSTFS_NOTIFY_WEBHOOK_ENDPOINT_PRIMARY=http://<host-ip>:3020/webhook \
-e RUSTFS_NOTIFY_WEBHOOK_QUEUE_DIR_PRIMARY=/tmp/rustfs-events \
rustfs/rustfs:latest
Notes:
RUSTFS_NOTIFY_ENABLE=trueenables the global notify module switch.- For ARN
arn:rustfs:sqs::primary:webhook, use instance-scoped env vars with_PRIMARY. - If queue dir is omitted, default is
/opt/rustfs/events; ensure it is writable by the container runtime user. RUSTFS_NOTIFY_WEBHOOK_SKIP_TLS_VERIFY_PRIMARYdefaults tofalse; enabling it skips webhook TLS certificate verification, allows MITM attacks, and emits a startup warning. PreferRUSTFS_NOTIFY_WEBHOOK_CLIENT_CA_PRIMARYfor private CAs.
NOTE: We recommend reviewing the docker-compose.yml file before running. It defines several services including Grafana, Prometheus, and Jaeger, which are helpful for RustFS observability. If you wish to start Redis or Nginx containers, you can specify the corresponding profiles.
3. Build from Source (Option 3) - Advanced Users
For developers who want to build RustFS Docker images from source with multi-architecture support:
# Build multi-architecture images locally
./docker-buildx.sh --build-arg RELEASE=latest
# Build and push to registry
./docker-buildx.sh --push
# Build specific version
./docker-buildx.sh --release v1.0.0 --push
# Build for custom registry
./docker-buildx.sh --registry your-registry.com --namespace yourname --push
The docker-buildx.sh script supports:
- Multi-architecture builds:
linux/amd64,linux/arm64 - Automatic version detection: Uses git tags or commit hashes
- Registry flexibility: Supports Docker Hub, GitHub Container Registry, etc.
- Build optimization: Includes caching and parallel builds
You can also use Make targets for convenience:
make docker-buildx # Build locally
make docker-buildx-push # Build and push
make docker-buildx-version VERSION=v1.0.0 # Build specific version
make help-docker # Show all Docker-related commands
Heads-up (macOS cross-compilation): macOS keeps the default
ulimit -nat 256, socargo zigbuildor./build-rustfs.sh --platform ...may fail withProcessFdQuotaExceededwhen targeting Linux. The build script attempts to raise the limit automatically, but if you still see the warning, runulimit -n 4096(or higher) in your shell before building.
4. Build with Helm Chart (Option 4) - Cloud Native
Follow the instructions in the Helm Chart README to install RustFS on a Kubernetes cluster.
For scanner pacing, cycle budgets, bitrot cadence, lifecycle transition status, and single-node single-disk idle CPU tuning, see Scanner Runtime Controls. For repeatable scanner-pressure validation, see Scanner Benchmark Runbook.
5. Nix Flake (Option 5)
If you have Nix with flakes enabled:
# Run directly without installing
nix run github:rustfs/rustfs
# Build the binary
nix build github:rustfs/rustfs
./result/bin/rustfs --help
# Or from a local checkout
nix build
nix run
6. X-CMD (Option 6)
If you are an x-cmd user:
# Run directly without installing
x rustfs
# Download the binary and install it to the global environment
x env use rustfs
rustfs --help
Accessing RustFS
- Access the Console: Open your web browser and navigate to
http://localhost:9001to access the RustFS console.- Default credentials:
rustfsadmin/rustfsadmin
- Default credentials:
- Create a Bucket: Use the console to create a new bucket for your objects.
- Upload Objects: You can upload files directly through the console or use S3-compatible APIs/clients to interact with your RustFS instance.
NOTE: To access the RustFS instance via https, please refer to the TLS Configuration Docs.
OIDC Roles Claim (Microsoft Entra ID)
RustFS supports mapping an OIDC claim containing role values into the existing
authorization pipeline. The roles_claim setting is optional: when unset or
empty, only the groups claim contributes to authorization (same as older
RustFS releases). For Microsoft Entra ID app roles, set roles_claim=roles so
both console admin checks and bucket IAM policies can evaluate those roles.
Example environment configuration (opt-in roles claim):
RUSTFS_IDENTITY_OPENID_ENABLE=on
RUSTFS_IDENTITY_OPENID_CONFIG_URL="https://login.microsoftonline.com/<tenant-id>/v2.0/.well-known/openid-configuration"
RUSTFS_IDENTITY_OPENID_CLIENT_ID="<client-id>"
RUSTFS_IDENTITY_OPENID_CLIENT_SECRET="<client-secret>"
RUSTFS_IDENTITY_OPENID_SCOPES="openid,profile,email"
RUSTFS_IDENTITY_OPENID_GROUPS_CLAIM="groups"
RUSTFS_IDENTITY_OPENID_ROLES_CLAIM="roles"
Policy condition example (evaluate app roles directly with jwt:roles; when
roles_claim is configured, RustFS also merges those values into jwt:groups
for backward compatibility with older policies):
{
"Version": "2012-10-17",
"Statement": [
{
"Effect": "Allow",
"Action": ["admin:*"],
"Resource": ["arn:aws:s3:::*"],
"Condition": {
"ForAnyValue:StringEquals": {
"jwt:roles": ["RustFS.ConsoleAdmin"]
}
}
}
]
}
