So this ZFS data corruption issue caused me being insecure about my data safety and to check my system for bit rot with btrfs scrubbing…
Scrub is a pass over all filesystem data and metadata and verifying the checksums. Basically, it reads all data on the disk, recomputes its checksum, and compares the recomputed checksum to the stored one. When the stored and recomputed checksums don’t match, the system knows there’s corruption.
