From working on the FailSafe project in 2000, I'm quite sure that is unlikely. It was a major pain to ensure that XFS/FailSafe did not violate anyone else's intellectual property and that SGI actually was in a position to Open Source them. I would be surprised if they could complete that exercise for CXFS today.

CXFS only uses Failsafe to distribute configuration information between systems, the original implementation did not use it at all. Then one day a VP level person said, use Failsafe for configuration and CXFS acquired umpteen thousand lines of code to implement a distributed database and a lot of pain. Some folks spent a lot of time updating Failsafe to not use sleeps as a synchronization mechanism to get the performance to acceptable levels.
There is some cool stuff in CXFS, but it was always very complex and extremely hard to deal with inter machine deadlocks. The version which became a product was the simplified version too.
