EIO errors are achieved usign the DM device. Also this test needs the latest btrfs-progs and kernel patch under title [PATCH] device delete by devid When this patch is not found in the btrfs-progs, this test will not run. However when the require patch is not found in the kernel it will fail gracefully.
