lỗi ioctl trong khi gửi btrfs

Tôi gặp lỗi này khi cố gắng sao lưu subvolume @home btrfs từ máy tính xách tay chạy Arch Linux vào ổ đĩa ngoài. Đây có vẻ là một lỗi đơn giản, nhưng điều kỳ lạ là tôi có thể sao lưu hai subvolume khác mà không thấy bất kỳ lỗi nào. Ổ đĩa sao lưu của tôi là ổ đĩa SATA bên trong Western Digital 1TB mà tôi đã kết nối bằng bộ điều hợp nguồn ổ cứng Sabrent và cáp eSATA sang SATA. Thông báo dưới đây dường như chỉ áp dụng khi tôi cố gắng sao lưu @home.

$ btrfs send hd/\@home-2016-02-04/ | btrfs receive bu
At subvol hd/@home-2016-02-04/
At subvol @home-2016-02-04
ERROR: send ioctl failed with -5: Input/output error
ERROR: unexpected EOF in stream.
$

Các thư mục hdvà buđược gắn vào cấp cao nhất của ổ đĩa trong của máy tính xách tay và ổ đĩa dự phòng của tôi, tương ứng. Ngoài ra, tôi đã chạy btrfs scrub start hd/\@homevà nó tìm thấy một "lỗi không thể sửa chữa."

Tôi có một số câu hỏi:

• Có ai biết lỗi này có nghĩa là gì không?
• Điều gì gây ra lỗi này?
• Làm sao để giải quyết vấn đề này?

Đây là dmesgđầu ra của việc bắt đầu khi bắt đầu một nỗ lực gửi subvolume.

Có vẻ như tôi đã làm cho nó hoạt động. Tôi đã trở lại phiên bản cũ hơn của @homesubvolume của mình và sao chép lại một số thay đổi đã xảy ra kể từ lần sao lưu cuối cùng. Khi tôi cố gắng sao chép hồ sơ Firefox của mình, nó không được chuyển hoàn toàn, vì vậy tôi chỉ cập nhật phiên bản cũ hơn.
