So a userspace fs, I'm guessing this will use fuse to actually expose a POSIX fs? Small sync writes will absolutely kill performance and will require all sorts of hacks like glusterfs has had to implement due to the amount of context switches. CoreOS really should have added whatever needed to ceph, filesystems are not something you just hack together overnight.

We had a POSIX interface early on (via FUSE), but decided to expose a a block storage interface first instead. This is not a "filesystem", it's a storage abstraction, and we've spent more than 6 months on it. Seems like a lot of folks are quickly jumping to conclusions, which is expected from "the internet", but I would have hoped for better from HN.

6 months is overnight in terms of a filesystem, there are literally millions of dollars of work that was done with glusterfs and probably a magnitude less man hours. I understand coreos wants.to innovate but what does torus bring to the table besides negatives and NIH?
