Actually this already works -- you are data safe if you run btrfs without a journal. Apparently it's even slower, though -- you need to go through a lot more syncs to guarantee your data safety. So your best bet if it's a real problem is to add a fast disk to use as your journaling device. -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
