If your software writes to disk, you can never know too much about your file system!
File systems offer a feature set often replicated, usually with less performance and reliability. In this talk, we will cover the file system notification infrastructure (inotify), locking (mandatory vs advisory and implications of distribution), movement guarantees (atomicity), and basic performance tuning. We will also cover how the primitive mechanisms available through file systems can be used to develop robust complex workflows.
If time permits, we will cover the current state of a two distributed file systems: Gluster and CephFS. Each present similar, but not always overlapping, feature sets.
