Could you build this?
No Creating a reliable log-structured filesystem mapped to object storage requires deep systems programming, kernel/FUSE interfaces, and distributed consistency expertise.
What it would actually take: Building ZeroFS requires a FUSE or NFS implementation written in Rust or C/C++ implementing POSIX file semantics over an append-only log model backed by S3. It necessitates custom block/inode caching layers, background garbage collection/compaction threads to prune superseded log segments, and conflict resolution/locking protocols to handle S3's eventual consistency characteristics and high latency.
Discussion
20 comments analyzed.
Competitors mentioned: Ceph (CephFS and RBD), JuiceFS, FiberFS, Lustre
Concerns raised: Poor performance on small I/O operations compared to Ceph, Data loss window and durability guarantees not clearly explained, Misleading latency benchmarks (footnote about S3 at rest doesn't match what's measured), Website requires JavaScript to display content, Need exhaustive testing for failure modes (power loss, server loss)
Feature requests: Generic offline caching layer for SMB/NFS with conflict resolution like Dropbox, HAProxy-style failover handling for NFS
