Go master must talk to Rust volume server seamlessly. +3. **HTTP API compatibility** — Same URL patterns, same JSON response shapes, same headers, same status codes. +4. **Replication protocol** — Write replication between Go and Rust volume servers must work bidirectionally. +5. **Heartbeat protocol** — Rust volume server must register with Go master and maintain heartbeat. +6. **CRC32 algorithm** — Must use IEEE polynomial (same as Go's `crc32.ChecksumIEEE`). +7. **JWT compatibility** — Tokens signed by Go filer/master must be verifiable by Rust volume server and vice versa. diff --git a/docker/Dockerfile.go_build b/docker/Dockerfile.go_build index c1c9a523e..3b8e120ed 100644 --- a/docker/Dockerfile.go_build +++ b/docker/Dockerfile.go_build @@ -16,9 +16,31 @@ RUN cd /go/src/github.com/seaweedfs/seaweedfs/weed \ && export LDFLAGS="-X github.com/seaweedfs/seaweedfs/weed/util/version.COMMIT=$(git rev-parse --short HEAD)" \ && CGO_ENABLED=0 go install -tags "$TAGS" -ldflags "-extldflags -static ${LDFLAGS}" +# Rust volume server builder (amd64/arm64 only) +FROM rust:1-alpine as rust_builder +ARG TARGETARCH +RUN apk add musl-dev protobuf-dev git +COPY --from=builder /go/src/github.com/seaweedfs/seaweedfs/seaweed-volume /build/seaweed-volume +COPY --from=builder /go/src/github.com/seaweedfs/seaweedfs/proto /build/proto +WORKDIR /build/seaweed-volume +ARG TAGS +RUN if [ "$TARGETARCH" = "amd64" ] || [ "$TARGETARCH" = "arm64" ]; then \ + if [ "$TAGS" = "5BytesOffset" ]; then \ + cargo build --release; \ + else \ + cargo build --release --no-default-features; \ + fi && \ + cp target/release/weed-volume /weed-volume; \ + else \ + echo "Skipping Rust build for $TARGETARCH (unsupported)" && \ + touch /weed-volume; \ + fi + FROM alpine AS final LABEL author="Chris Lu" COPY --from=builder /go/bin/weed /usr/bin/ +# Copy Rust volume server binary (real binary on amd64/arm64, empty placeholder on other platforms) +COPY --from=rust_builder /weed-volume /usr/bin/weed-volume RUN mkdir -p /etc/seaweedfs COPY --from=builder /go/src/github.com/seaweedfs/seaweedfs/docker/filer.toml /etc/seaweedfs/filer.toml COPY --from=builder /go/src/github.com/seaweedfs/seaweedfs/docker/entrypoint.sh /entrypoint.sh diff --git a/docker/entrypoint.sh b/docker/entrypoint.sh index 7d8bd24f2..6632f6645 100755 --- a/docker/entrypoint.sh +++ b/docker/entrypoint.sh @@ -72,6 +72,20 @@ case "$1" in exec /usr/bin/weed -logtostderr=true volume $ARGS $@ ;; + 'volume-rust') + ARGS="-dir /data -max 0" + if isArgPassed "-max" "$@"; then + ARGS="-dir /data" + fi + shift + if [ ! -s /usr/bin/weed-volume ]; then + echo "Error: Rust volume server is not available on this platform ($(uname -m))." >&2 + echo "Use 'volume' for the Go volume server instead." >&2 + exit 1 + fi + exec /usr/bin/weed-volume $ARGS $@ + ;; + 'server') ARGS="-dir=/data -volume.max=0 -master.volumeSizeLimitMB=1024" if isArgPassed "-volume.max" "$@"; then diff --git a/install.sh b/install.sh new file mode 100755 index 000000000..86b45f165 --- /dev/null +++ b/install.sh @@ -0,0 +1,275 @@ +#!/bin/bash +# +# SeaweedFS Installer +# Downloads Go and/or Rust binaries from GitHub releases. +# +# Usage: +# curl -fsSL https://raw.githubusercontent.com/seaweedfs/seaweedfs/master/install.sh | bash +# curl -fsSL ... | bash -s -- --component volume-rust --large-disk +# curl -fsSL ... | bash -s -- --version v3.93 --dir /usr/local/bin +# +# Options: +# --component COMP Which binary to install: weed, volume-rust, all (default: weed) +# --version VER Release version tag (default: latest) +# --large-disk Use large disk variant (5-byte offset, 8TB max volume) +# --dir DIR Installation directory (default: /usr/local/bin) +# --help Show this help message + +set -euo pipefail + +REPO="seaweedfs/seaweedfs" +COMPONENT="weed" +VERSION="" +LARGE_DISK=false +INSTALL_DIR="/usr/local/bin" + +# Colors (if terminal supports them) +if [ -t 1 ]; then + RED='\033[0;31m' + GREEN='\033[0;32m' + YELLOW='\033[0;33m' + BLUE='\033[0;34m' + NC='\033[0m' +else + RED='' GREEN='' YELLOW='' BLUE='' NC='' +fi + +info() { echo -e "${BLUE}[info]${NC} $*"; } +ok() { echo -e "${GREEN}[ok]${NC} $*"; } +warn() { echo -e "${YELLOW}[warn]${NC} $*"; } +error() { echo -e "${RED}[error]${NC} $*" >&2; exit 1; } + +usage() { + sed -n '/^# Usage:/,/^$/p' "$0" | sed 's/^# \?//' + exit 0 +} + +# Parse arguments +while [ $# -gt 0 ]; do + case "$1" in + --component) COMPONENT="$2"; shift 2 ;; + --version) VERSION="$2"; shift 2 ;; + --large-disk) LARGE_DISK=true; shift ;; + --dir) INSTALL_DIR="$2"; shift 2 ;; + --help|-h) usage ;; + *) error "Unknown option: $1.

Startup and harness alignment + Compared `weed/command/volume.go`, `test/volume_server/framework/cluster*.go`, `seaweed-volume/src/config.rs`, and `seaweed-volume/src/main.rs` to ensure the Rust server is invoked with Go-compatible flags and is rebuilt from the current source during parity runs. + +2. HTTP admin surface + Compared `weed/server/volume_server_handlers_admin.go` against `seaweed-volume/src/server/handlers.rs` with emphasis on `/status` payload shape, disk-status fields, and volume ordering. + +3. gRPC admin surface + Compared `weed/server/volume_grpc_admin.go` against `seaweed-volume/src/server/grpc_server.rs` with emphasis on `Ping`, `VolumeConfigure`, readonly/writable flows, and error wrapping. + +4. Storage/index layout + Compared Go index-entry defaults in `weed/storage/types` and `weed/storage/idx/*.go` against the Rust default feature set in `seaweed-volume/Cargo.toml` and the Rust index reader/writer paths to confirm default binaries use the same offset width. + +5.
