Research direction

Start with the linked circle_engineering issue #9 and clarify the undefined SSD cache size and the intended redundant-partition design. Review the existing ZOS filesystem support for the required Bcache and Btrfs configuration; done means an agreed implementation scope that meets the HDD minimum, cache, and data-integrity requirements.

Written by the indexing model from the issue text.

Description

type_feature

As per kds's request to support a new primitive file system that is enabled with Bcache, with a minimum of 0.1TB on HDD combined with a "to be defined" SSD space for caching. This configuration aims to enhance performance by leveraging SSD speeds for frequently accessed data while maintaining the larger storage capacity of HDDs.

It would be great to have two SSD partiions

  • a btrfs parition for the cache
  • a redundant partition on the SSD, to ensure data integrity and availability
