A Newly Proposed Linux Filesystem Can Fix Corrupted Data

Aurelien Desbrieres, the creator of BeamFS, has proposed an 18-patch update instead of merging his work. This proposal replaces his earlier FTRFS filesystem concept. BeamFS differs from filesystems like Btrfs and ZFS by incorporating Reed-Solomon error-correcting codes directly within each data block for repair. This design allows for the detection and correction of minor data damage during every read operation. If damage is too severe, BeamFS will report an error rather than return corrupted data. Testing showed that ext3 and ext4 returned incorrect data without errors, while Btrfs refused to read files. BeamFS, however, successfully returned correct data in most damage scenarios. The only failure occurred when a pointer to the data was corrupted, causing BeamFS to refuse the read. Desbrieres reportedly utilized Anthropic's Claude for code generation, patch verification, and the cover letter.
