说明
bcachefs is a next-generation copy-on-write filesystem for Linux that combines features of btrfs and ZFS with the performance characteristics of bcache. It provides checksumming, compression, encryption, snapshots, and multi-device support. The filesystem supports tiered storage with automatic data movement between fast (SSD) and slow (HDD) devices, making it suitable for hybrid storage configurations.
