Self-Healing Storage Format

The Self-Healing Storage Format is an advanced data layout for SeaweedFS Enterprise that automatically detects and removes corrupted data entries after unexpected server shutdowns or hardware failures. On startup, each volume server scans its local disks, discards any incomplete or corrupted entries, and reports back to the master before serving traffic — no manual intervention required.

When to use it

• A volume server loses power or crashes mid-write — incomplete or corrupted entries are identified and removed on the next startup.
• Hardware fails unexpectedly — the cluster returns to a consistent, reliable storage state automatically.
• You need high data integrity with minimal maintenance — no manual repair or recovery process to run after an outage.

How to use it

There’s nothing to configure or run. The Self-Healing Storage Format is built into the SeaweedFS Enterprise volume server. On every start, each volume server scans its local disks, removes any bad entries, reports back to the master, and only then begins serving requests — so the cluster comes back clean on its own.

Benefits

• Automatic corruption recovery — identifies and removes incomplete or corrupted entries after power loss or crashes.
• Data integrity — maintains a consistent and reliable storage state, even in the face of unexpected events.
• No manual intervention — reduces the need for manual repair or data recovery processes.
• Peace of mind — reduces the risk of data loss and operational downtime, ideal for businesses that require high data integrity and minimal maintenance.
