CharybdeFS: a new fault-injecting filesystem for software testing
- nickpsecurity 11y agoThis is really neat. Glad it was built. Im a big fan of using realistic mockups for analysis and fault detections. Especially needed for filesystems, networking stacks, distributed system assumptions, bitflips, and unauthorized code execution.
- creshal 11y agoSo Gluster, just better documented? /s
- thekozmo 11y agoCharybdeFS isn't a fully functional FS (unlike Gluster). It's whole purpose in life is to inject faults and delays in order to make sure the app on top doesn't crash
- Etzos 11y agoI think you may have missed that the parent post was sarcastic in nature. I'm fairly certain everyone here knows just from the title alone that CharybdeFS is made to insert faults. And I would assume most would know that Gluster is a fully functional filesystem. Sometimes it's just too hard to resist making a joke about the reliability of Gluster.

- btrask 11y agoThis appears similar to the "virtual filesystem" SQLite uses for testing[1], except of course this one is open source and easily reusable, since it exposes a regular filesystem interface via FUSE. This is fantastic news for every database (or, ahem, application that saves files), and a very good sign for ScyllaDB, since they are literally breaking new ground in reliability testing. You can bet this will turn up problems in at least a few other databases. FWIW, I asked for something like this a while back on HN.[2] Maybe someone saw it :) Thanks!
