houseme 6264be437c fix(storage): add scoped timeout policy and startup fs guardrail (#3056)
* fix(storage): add RUSTFS_NETWORK_MOUNT_MODE for CIFS/NFS backends

* style: fix cargo fmt formatting in disk_store.rs

* fix(storage): add RUSTFS_NETWORK_MOUNT_MODE for CIFS/NFS backends

Extend the TimeoutHealthAction introduced in #2996 to read_metadata,
list_dir, and disk_info operations when RUSTFS_NETWORK_MOUNT_MODE=true.
Also raises all drive operation timeouts to 60s (explicit per-operation
overrides still take precedence).

Closes #2790

* feat(startup): add unsupported filesystem policy guardrail

* chore(deps): refresh lockfile and dependency pins

* feat(ecstore): add scoped timeout health-action policy

* docs(config): document drive timeout health-action policy

* refactor(ecstore): cache timeout health policy per disk wrapper

* fix(storage): add RUSTFS_NETWORK_MOUNT_MODE for CIFS/NFS backends (#2838)

* fix(storage): add RUSTFS_NETWORK_MOUNT_MODE for CIFS/NFS backends

RustFS Config - Configuration Management

Configuration management and validation module for RustFS distributed object storage

CI 📖 Documentation · 🐛 Bug Reports · 💬 Discussions


📖 Overview

RustFS Config provides configuration management and validation capabilities for the RustFS distributed object storage system. For the complete RustFS experience, please visit the main RustFS repository.

Features

  • Multi-format configuration support (TOML, YAML, JSON, ENV)
  • Environment variable integration and override
  • Configuration validation and type safety
  • Hot-reload capabilities for dynamic updates
  • Default value management and fallbacks
  • Secure credential handling and encryption

📚 Documentation

For comprehensive documentation, examples, and usage guides, please visit the main RustFS repository.

Environment Variable Naming Conventions

RustFS uses a flat naming style for top-level configuration: environment variables are RUSTFS_* without nested module segments.

Examples:

  • RUSTFS_REGION
  • RUSTFS_ADDRESS
  • RUSTFS_VOLUMES
  • RUSTFS_LICENSE
  • RUSTFS_LICENSE_PUBLIC_KEY

Current guidance:

  • Prefer module-specific names only when they are not top-level product configuration.
  • Renamed variables must keep backward-compatible aliases until before beta.
  • Alias usage must emit deprecation warnings and be treated as transitional only.
  • Deprecated example:
    • RUSTFS_ENABLE_SCANNER -> RUSTFS_SCANNER_ENABLED
    • RUSTFS_ENABLE_HEAL -> RUSTFS_HEAL_ENABLED
    • RUSTFS_DATA_SCANNER_START_DELAY_SECS -> RUSTFS_SCANNER_START_DELAY_SECS

License environment variables

  • RUSTFS_LICENSE contains the signed license token.
  • RUSTFS_LICENSE_PUBLIC_KEY contains the RSA public key used to verify signed license tokens.

CORS environment variables

  • RUSTFS_CORS_ALLOWED_ORIGINS defaults to empty, so the S3 endpoint emits no generic CORS headers unless configured. Set * for wildcard origins without credentials, or a comma-separated allow-list for credentialed explicit origins.
  • RUSTFS_CONSOLE_CORS_ALLOWED_ORIGINS defaults to * for the console service.

Scanner environment aliases

  • RUSTFS_SCANNER_SPEED (canonical, also accepts MINIO_SCANNER_SPEED)
  • RUSTFS_SCANNER_CYCLE (canonical, also accepts MINIO_SCANNER_CYCLE)
  • RUSTFS_SCANNER_START_DELAY_SECS (canonical)
  • RUSTFS_DATA_SCANNER_START_DELAY_SECS (deprecated alias for compatibility)
  • RUSTFS_SCANNER_IDLE_MODE (canonical)
  • RUSTFS_SCANNER_CACHE_SAVE_TIMEOUT_SECS (canonical)

Drive timeout environment variables

  • RUSTFS_DRIVE_METADATA_TIMEOUT_SECS
  • RUSTFS_DRIVE_DISK_INFO_TIMEOUT_SECS
  • RUSTFS_DRIVE_LIST_DIR_TIMEOUT_SECS
  • RUSTFS_DRIVE_WALKDIR_TIMEOUT_SECS
  • RUSTFS_DRIVE_WALKDIR_STALL_TIMEOUT_SECS

Legacy compatibility fallback:

  • RUSTFS_DRIVE_MAX_TIMEOUT_DURATION This legacy variable is treated as a deprecated fallback for the operation-specific drive timeout variables above when a canonical variable is unset.

Drive timeout health-action policy:

  • RUSTFS_DRIVE_TIMEOUT_HEALTH_ACTION
    • mark_failure (default): timeout marks failure and may transition drive runtime state.
    • ignore_scanner: timeout does not mark failure for scanner-sensitive operations (walk_dir, read_metadata, list_dir, disk_info).

Drive timeout profile preset:

  • RUSTFS_DRIVE_TIMEOUT_PROFILE
    • default (default): keep current timeout defaults.
    • high_latency: use 60s default timeout for scanner-sensitive operations when no per-operation timeout override is set (read_metadata, disk_info, list_dir, walk_dir, walk_dir_stall).
  • Precedence:
    • Explicit per-operation timeout env (RUSTFS_DRIVE_*_TIMEOUT_SECS) takes highest precedence.
    • Then RUSTFS_DRIVE_MAX_TIMEOUT_DURATION legacy fallback.
    • Then the profile-derived default (default or high_latency).

Startup filesystem boundary policy

  • RUSTFS_UNSUPPORTED_FS_POLICY controls startup behavior when RustFS detects local endpoint filesystems that are outside the supported production boundary.
    • warn (default): log warning and continue startup.
    • fail: abort startup with an error.

RustFS production guidance remains direct-attached local POSIX filesystems. Network-mounted filesystems (for example nfs, cifs, smb2, and fuse.*) are treated as unsupported by this startup guard.
