As I understand it LLNL has very large datasets on ZFS on Linux. You could inquire with them, as well as http://groups.google.com/a/zfsonlinux.org/group/zfs-discuss/topics?pli=1 . My guess is that it's quite stable for at least some use cases (most likely: LLNL's!), but that may not be yours. You could always... test it, but if you do then please tell us how it went :)
