The kernel client is also just using a roundabout method for calculating free space, which we can change. Now that you've pointed it out though, we should have the userspace client do the same tradeoff for supporting a larger FS! -Greg-- 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
