Module scrub 

Data integrity scrubbing: verifying and repairing filesystem checksums

A scrub reads every data and metadata block on the filesystem, verifies it against its stored checksum, and repairs any errors it finds using redundant copies where available (e.g. RAID profiles). Scrubbing is the primary way to proactively detect silent data corruption.

Requires CAP_SYS_ADMIN.
