I gather that XtreemFS and Quobyte can tolerate benign but not byzantine faults. Is there such a thing as a byzantine fault tolerant file system?

  Yes, no byzantine faults.

  Since 1999: http://pmg.csail.mit.edu/papers/osdi99.pdf http://pmg.csail.mit.edu/papers/osdi99.pdf Google byzantine fault tolerance filesystems to get quite a few more.

    Okay, but are there any in-production file systems implementing that (or any other BFT consensus protocol)?

      That I'm aware of, nobody wants to pay the price for that. Much like with high assurance systems in general. Demos, prototypes, and so on available with no uptake due to tradeoffs involved. Or maybe I.P. issues, too.
