Does anybody know decision to make filesystem on top of a multiple files?

1. I found example of at at https://github.com/tspoolst/fuse-blockfs but unable to install it. It’s do exactly what I want. Maybe somebody know working alternatives?

2. Similar effect I get while using s3backer with --test option but the problem is that this application specialized on s3 storage and it’s just a feature for testing purpose. As a result it’s store file in a so strange way that its a problem with performance while I try to store large file in storage.

3. Another variant that I found is to make rclone chunk but have the similar problem as in previous case – to be able write to my large file I should make VFS with cache. And the volume of cache is staying a size of my large file, even if my large file only appended info at the end.

4. It’s possible to made it manually as described here . I’m steel didn’t try to do so. Maybe somebody know a good application to do it?

You can ask why I need so? Because I want to store large file ~ 100 Gb inside a small files and then put this small files to the remote and mount this remote (for example rclone mount) with a cache ~10 Gb. So, “cold” parts (or blocks) of large file will be stored remotely and “hot” parts will store locally in cache so application can use it.
