I think it is a matter of newlines in btrfs-progs and/or stdout/stderr mixup. You should run the command with -v and probably also with -f, so that it gets hopefully clearer what is wrong. That it fails on dropbox is an error I think, but maybe known: Could be mount option is compress and that that causes trouble for defrag although that should not happen. You can defrag just 1 file, so maybe you could try to make a reproducible case. What kernel? What btrfs-progs? > Question #2: > > Suppose that in above example /home/ftp is mounted as another btrfs > array (not subvolume).

I dont know, I dont think so, but you can simply try. -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
