Summary of Changes

Hello @ti-chi-bot, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request primarily enhances the TiDB documentation by adding critical information regarding supported file systems for production deployments. It also refines the terminology used for storage requirements, improving the clarity and accuracy of the hardware and software specifications.

Highlights

  • Documentation Update: Added a specific note to the hardware-and-software-requirements.md file, clarifying that TiDB officially supports XFS and Ext4 file systems, and advises against using others for production environments.
  • Terminology Refinement: Updated all instances of "Disk space requirements" to "Storage requirements" within the hardware-and-software-requirements.md document, including table headers and section titles, for improved clarity and consistency.
  • Linter Configuration: Added a new URL to the .lycheeignore file, likely to prevent link checker warnings for a newly referenced external resource.
