ODS-2 (the OpenVMS file system) is like that.  But you pay $15000
per CPU per year support, and it's a hell of a lot slower than ext3,
XFS, JFS, ReiserFS.

OpenVMS used to be more popular with geeks than Unix was.  But
businesses and Universities decided that it was worth it to trade 2
slow-but-reliable VAXen for 10 fast-but-flaky Suns.
