In this case, cfuse is probably more accurate -- the kernel client is doing some acrobatics with the page size so it can handle larger filesystems, but it trades off in accuracy for it. 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 [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
