I'm fairly certain this is Hardbrücke in Zürich, specifically right about here.

Chiming in to say that I've also experienced this on systems with an unresponsive NFS mount, although in that case it hangs until the connection is restored or the network operation times out.

Okay but how the hell does this happen???

Congratulations, that's the joke.

Yes, which is why these settings can also be configured per-directory as well as per-file.

It's not that obscure - I had a use case a while back where I had multiple rocksdb instances running on the same machine and wanted each of them to store their WAL only on SSD storage with compression and have the main tables be stored uncompressed on an HDD array with write-through SSD cache (ideally using the same set of SSDs for cost). I eventually did it, but it required partitioning the SSDs in half, using one half for a bcache (not bcachefs) in front of the HDDs and then using the other half of the SSDs to create a compressed filesystem which I then created subdirectories on and bind mounted each into the corresponding rocksdb database.

Yes, it works, but it's also ugly as sin and the SSD allocation between the cache and the WAL storage is also fixed (I'd like to use as much space as possible for caching). This would be just a few simple commands using bcachefs, and would also be completely transparent once configured (no messing around with dozens of fstab entries or bind mounts).
