Managing Disk Space - Teranode

Key considerations and strategies:

  1. Monitoring Disk Usage:

    • Regularly check available disk space using tools like df -h or through the Grafana dashboard.
    • Set up alerts to notify you when disk usage reaches certain thresholds (e.g., 80% or 85% full).

  2. Understanding Data Growth:

    • The blockchain data, transaction store, and subtree store will grow over time as new blocks are added to the network.
    • Growth rate depends on network activity and can vary significantly.

  3. Pruning Strategies:

    • Teranode implements regular pruning of old data that's no longer needed for immediate operations.
    • While retention policies for different data types are configurable, this is not documented in this guide.

  4. Log Management:

    • Consider offloading logs to a separate storage system or log management service.

  5. Backup and Recovery:

    • Implement a backup strategy that doesn't interfere with disk space management.
    • Ensure backups are stored on separate physical media or cloud storage.

  6. Performance Impact:

    • Be aware that very high disk usage (>90%) can negatively impact performance.
    • Monitor I/O performance alongside disk space usage.
