I believe the first version of this required the metadata to be stored on the ZeroFS server, making HA kinda hard.

This has changed now that if I stop the server and create a new instance with the same configuration file it'll pickup the existing metadata from the bucket?

Entrusting data storage to a vibe coded filesystem seems imprudent.

Is it? :) Ask me anything!

Here is my unsolicited advice:

If one of your goals is to get others to adopt the software, I recommend you redo the marketing page and readme from scratch. Delete them without looking at them again, then hand write the content for them. Once you have the content, you call tell an LLM to format it into a nice landing page, but strictly keep your wording without changes.

The 128 KiB chunk size is an interesting tradeoff point — small enough to avoid wasting bandwidth on partial reads, but you're still paying per-request overhead on S3 (both cost and latency) for anything that reads across many chunks. Curious how ZeroFS handles read-ahead/prefetching for sequential access patterns, since that's usually where these abstractions either save you or quietly rack up request costs. Tools like JuiceFS and SeaweedFS handle this differently (local metadata cache + larger block coalescing) — would be interesting to see a head-to-head on request volume for the same workload.

From the docs: > ZeroFS fetches object data in 128 KiB parts Read/write operations in object storage are _far more_ expensive than stored bytes. I'm always afraid of anything that abstracts over S3/GCS access specifically for that reason.

One of the reasons why ZeroFS seems interesting is they use SlateDB under the hood, which optimizes the requests that hit S3 behind the scenes.

That's fair advice, thanks.
