There was a similar issue in btrfs-progs 3.16 that was fixed in 3.16.1 by this commit: https://git.kernel.org/cgit/linux/kernel/git/mason/btrfs-progs.git/commit/?id=6a47725a6fb8a463dd60611800222c7297195588 I'd do a quick `btrfs --version` just to make sure you're running the version you think you are. Otherwise, the output of `mount` might shed some light on why you're getting this. -- Omar -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
