MogileFS isn't really a file system. There is a FUSE plugin but nobody
really wants to use it that way. It works basically identically to S3
and Swift for a single tenant, though its APIs is a native protocol
instead of HTTP (uploads and downloads are still HTTP). It doesn't have
the concept of "containers" and is just a big flat key/value store,
and it doesn't have multi-tenants, but it is basically a predecessor of
today's object stores.
