RustFS Single Node Multiple Disk Installation

Install RustFS on a single server with multiple disks, data will be stored on multiple disks.

In Single Node Multiple Disk (SNMD) mode, one server stores data in sharded form across multiple data disks. Each object is split into K data shards and M parity shards (erasure coding), so the loss of up to M disks does not cause data loss.

SNMD is suitable for medium, non-critical business. Damage to at most M disks does not pose a data risk, but if the entire server fails or more than M disks are damaged, data will be lost. Keep backups of important data. For node-level fault tolerance, use MNMD.

Topology and Planning

1 server with multiple data disks (this example uses 4 disks mounted at /data/rustfs0 through /data/rustfs3).
Erasure coding spreads data and parity shards across the disks; fault tolerance is limited to disk failures within the single node.
Format each disk with XFS and mount it separately (e.g., labels RUSTFS0 – RUSTFS3), as described in the prerequisites page.
For production deployments, also review the Pre-Installation Checklists.

Prerequisites and Service Setup

Complete the common prerequisites and service setup — operating system, firewall, time synchronization, disk formatting, service user, binary download, and systemd unit — then continue below.

Configure Environment Variables

Create the configuration file. RUSTFS_VOLUMES uses brace expansion to enumerate the four disk mount points:

/etc/default/rustfs

# Use a unique access key and a strong, random secret (e.g. openssl rand -base64 24)
RUSTFS_ACCESS_KEY=<your-access-key>
RUSTFS_SECRET_KEY=<your-secret-key>
RUSTFS_VOLUMES="/data/rustfs{0...3}"
RUSTFS_ADDRESS=":9000"
RUSTFS_CONSOLE_ENABLE=true
RUST_LOG=error
RUSTFS_OBS_LOG_DIRECTORY="/var/logs/rustfs/"

Create the storage and log directories:

sudo mkdir -p /data/rustfs{0..3} /var/logs/rustfs /opt/tls
sudo chmod -R 750 /data/rustfs* /var/logs/rustfs

Start Service and Verification

Start the service and enable auto-start on boot:

sudo systemctl enable --now rustfs

Verify the service status:

systemctl status rustfs

Check the service port:

netstat -ntpl

View log files:

tail -f /var/logs/rustfs/rustfs*.log

Access the console: enter the server's IP address and the console port (default 9001) in a browser. You should see:
