Fusequota

Fusequota is a user-space filesystem built on FUSE (Filesystem in Userspace) that enforces per-server disk limits. It works on top of whatever filesystem your server volumes already live on - ext4, XFS, network mounts, and others - without requiring native filesystem support for quotas.

How It Works

Wings spawns a dedicated FUSE daemon process per server. The daemon intercepts all filesystem calls and tracks cumulative disk usage, rejecting writes that would exceed the configured server disk limit.

Strengths

• Works on any filesystem type - no migration required
• Existing server data does not need to be moved or reformatted
• Compatible with standard server volume layouts

Limitations

• Performance - FUSE operates in user-space, introducing overhead on every filesystem operation. High-I/O games (Minecraft chunk generation, database-heavy games) will see a measurable impact.
• Stability - FUSE mounts can get stuck on process crash or unexpected restart, leaving server directories inaccessible until the mount is manually cleaned up.
• Game compatibility - Some games and mods use filesystem operations that behave incorrectly under FUSE.
• Docker incompatibility - Fusequota is strongly discouraged with Docker-based Wings installations. Docker restart cycles can leave orphaned FUSE mounts that require manual cleanup.

When to Use

Use Fusequota only when your host filesystem does not support Btrfs, ZFS, or XFS project quotas, and you still need disk limit enforcement (e.g. in a shared or low-trust environment).

Configuration

In /etc/pterodactyl/config.yml, set:

system:
  disk_limiter_mode: fuse_quota

Restart Wings after changing this value.
