(this is a request for a "that's stupid", not a suggestion of something people should do at this point) An idea that's been floating around in my head, inspired by the ZFS "scrubbing" idea: rather than build that "check your data" process into the file system, just do something periodically like this: # dd if=/dev/rsd0c of=/dev/null bs=1m
There is a lot of prior art on this concept. See https://www.nsc.liu.se/lcsc2007/presentations/LCSC_2007-kelemen.pdf for analysis of failure modes and frequencies. There is a background processing tool proposed too. See https://marc.info/?l=openbsd-ports&m=122889297621831&w=2 for a (probably terrible attempt at a) port. There was another thread titled "Ensuring data integrity" which I just noticed. It seems people adopt an assumption that a file system is the best way to store data. A slightly less conditioned view is to consider files, databases, and "objects" as possible solutions to a data storage problem or problems. "Just pick the best one." "Objects", aka AWS S3 to many people, is easily available on OpenBSD as minio and the replication options in that are many. Of course if you have 20GB of files accumulated in 20-years this newfangled database stuff won't fly. J
