Standard
Network File System: a distributed file system protocol letting clients access files over a network as if local, widely used for shared storage.
SQLite's WAL mode coordinates readers through a shared-memory index file, so every process using the database must run on the host that stores it. Tuning mounts and timeouts on NFS or SMB can quiet the symptoms without making a multi-host setup safe, a dev.to analysis argues.
Reality
An air-gapped cluster of 10 servers runs every workload on NFS. The write-up blames that for Elasticsearch and Zeebe I/O failures, and its own numbers rule out Longhorn and local-path on ~100GB node disks.
Reality
Duplicate side effects all return 200, so nothing alerts on them. The write side of a file-based guard is a single O_EXCL create and it holds under forty processes; every defect four review rounds found afterwards sat in reclaim and in reads.
Reality
A dev.to writeup reduces the storage choice to a property test on the calling code. The part worth arguing about is when each wrong answer shows up: on the first query, or at 10 million files.
Reality
A dev.to post turns one atomic mkdir into a logged, self-healing lock for parallel agents. The mechanism holds up. The shipped defaults are the part to read closely.
