ReadParts built its disk-health trace path from partMetaPaths[0] with no length check, so a caller passing no paths at all indexed an empty slice. xlStorage.ReadParts handles an empty list perfectly well - it returns an empty result - so the panic came entirely from the metrics bookkeeping wrapped around it. The reachable caller is ReadPartsHandler, which decodes its path list from a msgpack request body that an authenticated peer controls, and neither the handler, the storage-REST client, nor the path guard rejects an empty one: guardPaths ranges over the slice, so an empty slice passes vacuously. net/http recovers a panicking handler, so this is not a crash - which is what makes it worth fixing rather than merely tidy. ReadPartsHandler calls keepHTTPResponseAlive before it calls ReadParts, and that helper spawns a goroutine whose only exit is receiving from the channel done() writes. Panicking in between skips both done(err) and done(nil), so the process survives and the keep-alive goroutine and its ten-second ticker stay parked forever - one per request, driven by a request body the caller chooses. Repeating one malformed frame exhausts the node. The fix follows DeleteVersions in the same decorator, which already guards the identical "merely for tracing" lookup; ReadParts was the one method missing the pattern. It also covers the second entry point, the per-disk errgroup in readParts, where a panic has no recover at all and would take the process down. That path is screened at the S3 boundary today, so this is defence in depth there. No error is returned for the empty case. The storage layer's answer to an empty list is an empty result, and turning that into an error would be a behaviour change on a path that is merely degenerate.

Silo
A conservatively maintained MinIO fork
Security maintenance, versioned release artifacts, and operational continuity for existing deployments.
中文 · Documentation · Releases · Container Images · Security
Important
Silo is an independent, community-maintained fork of the open-source MinIO server, published by Pigsty from
pgsty/minio. It is not affiliated with, endorsed by, or sponsored by MinIO, Inc. “MinIO” is used only to identify the upstream project and compatibility lineage.
Overview
Silo maintains one downstream release line based on MinIO RELEASE.2025-12-03T12-00-00Z. It provides maintained builds and release artifacts for existing MinIO-compatible deployments after upstream community distribution ended.
Pigsty uses this fork for object storage, including PostgreSQL backups.
Maintenance Policy
The active release line covers:
- build and dependency maintenance;
- applicable security fixes and advisories;
- focused fixes for reproducible defects;
- versioned binaries, packages, checksums, and multi-architecture images;
- the web console, client, documentation, and Pigsty integration.
Changes are kept narrow and tested where practical. Maintenance is best effort; no response, remediation, or release schedule is guaranteed.
Out of scope
- a separate product roadmap, new storage engine, or speculative S3 features;
- broad rewrites or changes that materially expand the downstream delta;
- historical releases or multiple support branches;
- commercial support, SLAs, 24×7 coverage, or SUBNET access;
- deployment design, access control, monitoring, backup, or recovery.
Compatibility
Silo aims to preserve:
- the
minioexecutable andgithub.com/minio/miniomodule path; - MinIO-compatible S3 APIs, configuration, environment variables, and CLI conventions;
RELEASE.YYYY-MM-DDTHH-MM-SSZtags, container entrypoints, and common deployment workflows.
Compatibility is a goal, not a guarantee. Security fixes may change behavior. Treat each release as a downstream upgrade: pin versions, review release notes and security advisories, keep a rollback path, and test before production use.
Release Artifacts
| Artifact | Location |
|---|---|
| Source | github.com/pgsty/minio |
| Container image | pgsty/minio, multi-arch for linux/amd64 and linux/arm64 |
| Server binaries | GitHub Releases for Linux, macOS, and Windows on amd64 and arm64 |
| Linux packages | RPM, DEB, and APK artifacts, also distributed through the Pigsty repository |
| Client | pgsty/mc, bundled in the container as mcli with an mc compatibility alias |
| Console | Maintained georgmangold/console fork, embedded in the server build |
| Documentation | English, Chinese, and pgsty/minio-docs |
| Security record | SECURITY.md, VULNERABILITY_REPORT.md, and fork advisories |
Quick Start
For local evaluation:
mkdir -p data
export MINIO_ROOT_USER=minioadmin
export MINIO_ROOT_PASSWORD=change-me-long-password
docker run -d --name silo \
-p 9000:9000 \
-p 9001:9001 \
-e MINIO_ROOT_USER \
-e MINIO_ROOT_PASSWORD \
-v "$PWD/data:/data" \
pgsty/minio:latest server /data --console-address ":9001"
Open the console at http://localhost:9001; the S3 API listens on http://localhost:9000.
The image includes the compatible client as mcli:
docker exec silo mcli alias set local http://127.0.0.1:9000 \
"$MINIO_ROOT_USER" "$MINIO_ROOT_PASSWORD"
docker exec silo mcli mb local/demo
docker exec silo mcli ls local
Warning
For production, pin a release, use unique credentials and TLS, monitor the service, keep independent backups, and test recovery.
Build the server from source:
go build -o minio .
./minio --version

Security
Security fixes target the active master branch and are recorded in the advisory log. Report vulnerabilities privately as described in SECURITY.md and VULNERABILITY_REPORT.md. Report issues that also affect upstream MinIO there as well.
Contributing
Useful contributions include security and dependency updates, reproducible bug fixes, tests, release automation, packaging, and documentation.
Issues and pull requests should include the affected version, reproduction steps, impact, expected behavior, tests, and compatibility notes. Discuss large changes in an issue first.
