-RustFS is a high-performance distributed object storage software built using Rust, one of the most popular languages worldwide. Along with MinIO, it shares a range of advantages such as simplicity, S3 compatibility, open-source nature, support for data lakes, AI, and big data. Furthermore, it has a better and more user-friendly open-source license in comparison to other storage systems, being constructed under the Apache license. As Rust serves as its foundation, RustFS provides faster speed and safer distributed features for high-performance object storage.

-| Does not report logs to third-party countries  | Reporting logs to other third countries may violate national security laws |
-| Licensed under Apache, more business-friendly  | AGPL V3 License and other License, polluted open source and License traps, infringement of intellectual property rights |
-| Comprehensive S3 support, works with domestic and international cloud providers  | Full support for S3, but no local cloud vendor support |
-| Rust-based development, strong support for secure and innovative devices  | Poor support for edge gateways and secure innovative devices|
-| Stable commercial prices, free community support | High pricing, with costs up to $250,000 for 1PiB |
-| No risk | Intellectual property risks and risks of prohibited uses |

+# Install rustfs with mnmd mode using ansible
+
+This chapter show how to install rustfs with mnmd(multiple nodes multiple disks) using ansible playbook.Two installation method are available, namely binary and docker compose.
+
+## Requirements
+
+- Multiple nodes(At least 4 nodes,each has private IP and public IP)
+- Multiple disks(At least 1 disk per nodes, 4 disks is a better choice)
+- Ansible should be available
+- Docker should be available(only for docker compose installation)
+
+## Binary installation and uninstallation
+
+### Installation
+
+For binary installation([script installation](https://rustfs.com/en/download/),you should modify the below part of the playbook,
+
+```
+- name: Modify Target Server's hosts file
+  blockinfile:
+    path: /etc/hosts
+    block: |
+      172.92.20.199  rustfs-node1
+      172.92.20.200  rustfs-node2
+      172.92.20.201  rustfs-node3
+      172.92.20.202  rustfs-node4
+```
+
+Replacing the IP with your nodes' **private IP**.If you have more than 4 nodes, adding the ip in order.
+
+Running the command to install rustfs
+
+```
+ansible-playbook --skip-tags rustfs_uninstall binary-mnmd.yml
+```
+
+After installation success, you can access the rustfs cluster via any node's public ip and 9000 port. Both default username and password are `rustfsadmin`.
+
+
+### Uninstallation
+
+Running the command to uninstall rustfs
+
+```
+ansible-playbook --tags rustfs_uninstall binary-mnmd.yml
+```
+
+## Docker compose installation and uninstallation
+
+**NOTE**: For docker compose installation,playbook contains docker installation task,
+
+```
+tasks:
+  - name: Install docker
+    shell: |
+          apt-get remove -y docker docker.io containerd runc || true
+          apt-get update -y
+          apt-get install -y ca-certificates curl gnupg lsb-release
+          install -m 0755 -d /etc/apt/keyrings
+          curl -fsSL https://mirrors.aliyun.com/docker-ce/linux/ubuntu/gpg | gpg --dearmor --yes -o /etc/apt/keyrings/docker.gpg
+          chmod a+r /etc/apt/keyrings/docker.gpg
+          echo \
+            "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] https://mirrors.aliyun.com/docker-ce/linux/ubuntu \
+            $(lsb_release -cs) stable" | tee /etc/apt/sources.list.d/docker.list > /dev/null
+          apt-get update -y
+          apt-get install -y docker-ce docker-ce-cli containerd.io docker-compose-plugin
+    become: yes
+    register: docker_installation_result
+    changed_when: false
+
+  - name: Installation check
+    debug:
+      var: docker_installation_result.stdout
+```
+
+If your node already has docker environment,you can add `tags` in the playbook and skip this task in the follow installation.By the way, the docker installation only for `Ubuntu` OS,if you have the different OS,you should modify this task as well.
+
+For docker compose installation,you should also modify the below part of the playbook,
+
+```
+extra_hosts:
+  - "rustfs-node1:172.20.92.202"
+  - "rustfs-node2:172.20.92.201"
+  - "rustfs-node3:172.20.92.200"
+  - "rustfs-node4:172.20.92.199"
+```
+
+Replacing the IP with your nodes' **private IP**.If you have more than 4 nodes, adding the ip in order.
+
+Running the command to install rustfs,
+
+```
+ansible-playbook --skip-tags docker_uninstall docker-compose-mnmd.yml
+```
+
+After installation success, you can access the rustfs cluster via any node's public ip and 9000 port. Both default username and password are `rustfsadmin`.
+
+### Uninstallation
+
+Running the command to uninstall rustfs
+
+```
+ansible-playbook --tags docker_uninstall docker-compose-mnmd.yml
+```

-# Append Write Design
-
-This document captures the current design of the append-write feature in RustFS so that new contributors can quickly understand the moving parts, data flows, and testing expectations.
-
-## Goals & Non-Goals
-
-### Goals
- Allow clients to append payloads to existing objects without re-uploading the full body.
- Support inline objects and spill seamlessly into segmented layout once thresholds are exceeded.
- Preserve strong read-after-write semantics via optimistic concurrency controls (ETag / epoch).
- Expose minimal S3-compatible surface area (`x-amz-object-append`, `x-amz-append-position`, `x-amz-append-action`).
-
-### Non-Goals
- Full multipart-upload parity; append is intentionally simpler and serialized per object.
- Cross-object transactions; each object is isolated.
- Rebalancing or background compaction (future work).
-
-## State Machine
-
-Append state is persisted inside `FileInfo.metadata` under `x-rustfs-internal-append-state` and serialized as `AppendState` (`crates/filemeta/src/append.rs`).
-
-```
-Disabled --(initial PUT w/o append)--> SegmentedSealed
-Inline --(inline append)--> Inline / InlinePendingSpill
-InlinePendingSpill --(spill success)--> SegmentedActive
-SegmentedActive --(Complete)--> SegmentedSealed
-SegmentedActive --(Abort)--> SegmentedSealed
-SegmentedSealed --(new append)--> SegmentedActive
-```
-
-Definitions:
- **Inline**: Object data fully stored in metadata (`FileInfo.data`).
- **InlinePendingSpill**: Inline data after append exceeded inline threshold; awaiting spill to disk.
- **SegmentedActive**: Object data lives in erasure-coded part(s) plus one or more pending append segments on disk (`append/<epoch>/<uuid>`).
- **SegmentedSealed**: No pending segments; logical content equals committed parts.
-
-`AppendState` fields:
- `state`: current state enum (see above).
- `epoch`: monotonically increasing counter for concurrency control.
- `committed_length`: logical size already durable in the base parts/inline region.
- `pending_segments`: ordered list of `AppendSegment { offset, length, data_dir, etag, epoch }`.
-
-## Metadata & Storage Layout
-
-### Inline Objects
- Inline payload stored in `FileInfo.data`.
- Hash metadata maintained through `append_inline_data` (re-encoding with bitrot writer when checksums exist).
- When spilling is required, inline data is decoded, appended, and re-encoded into erasure shards written to per-disk `append/<epoch>/<segment_id>/part.1` temporary path before rename to primary data directory.
-
-### Segmented Objects
- Base object content is represented by standard erasure-coded parts (`FileInfo.parts`, `FileInfo.data_dir`).
- Pending append segments live under `<object>/append/<epoch>/<segment_uuid>/part.1` (per disk).
- Each append stores segment metadata (`etag`, `offset`, `length`) inside `AppendState.pending_segments` and updates `FileInfo.size` to include pending bytes.
- Aggregate ETag is recomputed using multipart MD5 helper (`get_complete_multipart_md5`).
-
-### Metadata Writes
- `SetDisks::write_unique_file_info` persists `FileInfo` updates to the quorum of disks.
- During spill/append/complete/abort, all mirrored `FileInfo` copies within `parts_metadata` are updated to keep nodes consistent.
- Abort ensures inline markers are cleared (`x-rustfs-internal-inline-data`) and `FileInfo.data = None` to avoid stale inline reads.
-
-## Request Flows
-
-### Append (Inline Path)
-1. Handler (`rustfs/src/storage/ecfs.rs`) validates headers and fills `ObjectOptions.append_*`.
-2. `SetDisks::append_inline_object` verifies append position using `AppendState` snapshot.
-3. Existing inline payload decoded (if checksums present) and appended in-memory (`append_inline_data`).
-4. Storage class decision determines whether to remain inline or spill.
-5. Inline success updates `FileInfo.data`, metadata, `AppendState` (state `Inline`, lengths updated).
-6. Spill path delegates to `spill_inline_into_segmented` (see segmented path below).
-
-### Append (Segmented Path)
-1. `SetDisks::append_segmented_object` validates state (must be `SegmentedActive` or `SegmentedSealed`).
-2. Snapshot expected offset = committed length + sum of pending segments.
-3. Payload encoded using erasure coding; shards written to temp volume; renamed into `append/<epoch>/<segment_uuid>` under object data directory.
-4. New `AppendSegment` pushed, `AppendState.epoch` incremented, aggregated ETag recalculated.
-5. `FileInfo.size` reflects committed + pending bytes; metadata persisted across quorum.
-
-### GET / Range Reads
-1. `SetDisks::get_object_with_fileinfo` inspects `AppendState`.
-2. Reads committed data from inline or erasure parts (ignoring inline buffers once segmented).
-3. If requested range includes pending segments, loader fetches each segment via `load_pending_segment`, decodes shards, and streams appended bytes.
-
-### Complete Append (`x-amz-append-action: complete`)
-1. `complete_append_object` fetches current `FileInfo`, ensures pending segments exist.
-2. Entire logical object (committed + pending) streamed through `VecAsyncWriter` (TODO: potential optimization) to produce contiguous payload.
-3. Inline spill routine (`spill_inline_into_segmented`) consolidates data into primary part, sets state `SegmentedSealed`, clears pending list, updates `committed_length`.
-4. Pending segment directories removed and quorum metadata persisted.
-
-### Abort Append (`x-amz-append-action: abort`)
-1. `abort_append_object` removes pending segment directories.
-2. Ensures `committed_length` matches actual durable data (inline length or sum of parts); logs and corrects if mismatch is found.
-3. Clears pending list, sets state `SegmentedSealed`, bumps epoch, removes inline markers/data.
-4. Persists metadata and returns base ETag (multipart MD5 of committed parts).
-
-## Error Handling & Recovery
-
- All disk writes go through quorum helpers (`reduce_write_quorum_errs`, `reduce_read_quorum_errs`) and propagate `StorageError` variants for HTTP mapping.
- Append operations are single-threaded per object via locking in higher layers (`fast_lock_manager` in `SetDisks::put_object`).
- On spill/append rename failure, temp directories are cleaned up; operation aborts without mutating metadata.
- Abort path now realigns `committed_length` if metadata drifted (observed during development) and strips inline remnants to prevent stale reads.
- Pending segments are only removed once metadata update succeeds; no partial deletion is performed ahead of state persistence.
-
-## Concurrency
-
- Append requests rely on exact `x-amz-append-position` to ensure the client has an up-to-date view.
- Optional header `If-Match` is honored in S3 handler before actual append (shared with regular PUT path).
- `AppendState.epoch` increments after each append/complete/abort; future work may expose it for stronger optimistic control.
- e2e test `append_segments_concurrency_then_complete` verifies that simultaneous appends result in exactly one success; the loser receives 400.
-
-## Key Modules
-
- `crates/ecstore/src/set_disk.rs`: core implementation (inline append, spill, segmented append, complete, abort, GET integration).
- `crates/ecstore/src/erasure_coding/{encode,decode}.rs`: encode/decode helpers used by append pipeline.
- `crates/filemeta/src/append.rs`: metadata schema + helper functions.
- `rustfs/src/storage/ecfs.rs`: HTTP/S3 layer that parses headers and routes to append operations.
-
-## Testing Strategy
-
-### Unit Tests
- `crates/filemeta/src/append.rs` covers serialization and state transitions.
- `crates/ecstore/src/set_disk.rs` contains lower-level utilities and regression tests for metadata helpers.
- Additional unit coverage is recommended for spill/append failure paths (e.g., injected rename failures).
-
-### End-to-End Tests (`cargo test --package e2e_test append`)
- Inline append success, wrong position, precondition failures.
- Segmented append success, wrong position, wrong ETag.
- Spill threshold transition (`append_threshold_crossing_inline_to_segmented`).
- Pending segment streaming (`append_range_requests_across_segments`).
- Complete append consolidates pending segments.
- Abort append discards pending data and allows new append.
- Concurrency: two clients racing to append, followed by additional append + complete.
-
-### Tooling Considerations
- `make clippy` must pass; the append code relies on async operations and custom logging.
- `make test` / `cargo nextest run` recommended before submitting PRs.
- Use `RUST_LOG=rustfs_ecstore=debug` when debugging append flows; targeted `info!`/`warn!` logs are emitted during spill/abort.
-
-## Future Work
-
- Streamed consolidation in `complete_append_object` to avoid buffering entire logical object.
- Throttling or automatic `Complete` when pending segments exceed size/quantity thresholds.
- Stronger epoch exposure to clients (header-based conflict detection).
- Automated cleanup or garbage collection for orphaned `append/*` directories.
