Title
Automatic RAID bit flip correction
Goal
Correct single-bit errors on storage devices
Description
Modern hard disks and SSDs corrupt data at a fairly predictable rate. Integrity-checking filesystems and software RAID schemes protect against this by using various checksumming approaches to detect corrupt blocks; if a corrupt block is detected, it must be obtained from another copy of the data. However, since the most common type of corruption is a single bit being flipped, it should also be possible to try to repair a corrupt block by flipping individual bits and seeing whether the checksum is correct. Implement and evaluate this scheme inside Linux software RAID or btrfs.
