Even with journaling, you might need one. ZeroFS [0] almost had a lost+found directory (even with the WAL enabled), because you might have consistency issues between your in-memory state and what was flushed, and especially in what order.

ZeroFS ended up not needing recovery at all through atomic, strictly ordered commits [1], but it was far from trivial (and not just a matter of requiring a WAL).

https://github.com/Barre/ZeroFS Should do a great job at this.

It's definitely shared, and can be redundant.

Or ZeroFS which doesn’t require a 3rd party database, just a s3 bucket!

Doesn’t require an external database (just a s3 bucket) and is a single binary. A webui is shipping in the next few days.

As of recently (workflows worked for months) I even have part of my CI on actions that fails with [0]

2026-02-27T10:11:51.1425380Z ##[error]The runner has received a shutdown signal. This can happen when the runner service is stopped, or a manually started runner is canceled. 2026-02-27T10:11:56.2331271Z ##[error]The operation was canceled.

I had to disable the workflows.

GitHub support response has been

“ We recommend reviewing the specific job step this occurs at to identify any areas where you can lessen parallel operations and CPU/memory consumption at one time.”

That plus other various issues makes me start to think about alternatives, and it would have never occurred to me one year back.

I am not sure to understand what this is this achieving compared to just assigning a ip + port per vm?

You might be interested in ZeroFS [0], it works great with Postgres [1].

To achieve what you describe, you should be just able to setup a Postgres replica that’s setup on top of ZeroFS.

ZeroFS [0] is very thankful for what it brought to Linux with the v9fs [1] subsystem which is very nice to work with (network native) compared to fuse :)

It’s not great UX on that angle. I am currently working on coordination (through s3, not node to node communication), so that you can just spawn instances without thinking about it.

Indeed.

It doesn’t, you are free to use ZeroFS for commercial and closed source products.

> but I find it kind of off-putting for you to come in and immediately put down JuiceFS, especially with benchmark results that don't make a ton of sense, and are likely making apples-to-oranges comparisons with how JuiceFS works or mount options.

The benchmark suite is trivial and opensource [1].

Is performing benchmarks “putting down” these days?

If you believe that the benchmarks are unfair to juicefs for a reason or for another, please put up a PR with a better methodology or corrected numbers. I’d happily merge it.

EDIT: From your profile, it seems like you are running a VC backed competitor, would be fair to mention that…

ZeroFS [0] outperforms JuiceFS on common small file workloads [1] while only requiring S3 and no 3rd party database.

ZeroFS author here.

LSMs are “for small burst workloads kept in memory”? That’s just incorrect. “Once compaction hits all bets are off” suggests a misunderstanding of what compaction is for.

“Playing with fire,” “not sure about crash consistency,” “all bets are off”

Based on what exactly? ZeroFS has well defined durability semantics, guarantees which are much stronger than local block devices. If there’s a specific correctness issue, name it.

“ZFS special vdev + ZIL is much safer”

Safer how?
