在从外部 LUKS raid 10 阵列（通过 e-sata 连接）到内部驱动器的 rsync 期间，操作系统冻结。
重新启动后，我无法再访问外部 RAID 10。当我单击它时，我收到以下错误消息：
Error mounting filesystem
Error mounting /dev/dm-0 at /media/marco/EXT_RAID_10: can't read superblock
on /dev/mapper/luks-49aa238c-96bc-4bf6-abeb-1f4b018ccabe (udisks-error-quark, 0)
该系统是带有 Budgie 桌面的 Ubuntu 服务器 18.04.3。所有 4 个驱动灯都亮起，表明它们应该没问题

sudo fsck.ext4 -v /dev/sdf1 的输出：

fsck.ext4: Bad magic number in super-block while trying to open /dev/sdf1
The superblock could not be read or does not describe a valid ext2/ext3/ext4
filesystem. If the device is valid and it really contains an ext2/ext3/ext4
filesystem (and not swap or ufs or something else), then the superblock
is corrupt, and you might try running e2fsck with an alternate superblock:
e2fsck -b 8193 <device>
or
e2fsck -b 32768 <device>
/dev/sdf1 contains a crypto_LUKS filesystem

最后，问题只是驱动器由于中断的 rsync 命令而被锁定（当我中断一个简单的 cp 命令时也发生了）。LUKS 加密使这个简单的锁定变得复杂，给出了神秘的（双关语）错误消息。我通过按照以下说明移除锁解决了这个问题： https ://alvinabad.wordpress.com/2012/09/22/how-to-recover-a-luks-encrypted-disk/
简而言之：
1. Boot from a recovery disk
2. Determine /dev address of locked LUKS partition (in this case /dev/sdh1):
~$ sudo fdisk -l
3. Display LUKS header info:
~$ sudo cryptsetup -v luksDump /dev/sdh1
4. Unlock partition with LUKS passphrase:
~$ sudo cryptsetup -v luksOpen /dev/sdh1 sdh1_crypt
5. Mount drive using Nautilus or manually:
~$ mkdir /tmp/disk
~$ sudo mount /dev/mapper/sdh1_crypt /tmp/disk
改变了电缆并做到了这一点： https ://alvinabad.wordpress.com/2012/09/22/how-to-recover-a-luks-encrypted-disk/
为我工作：
但是，我没有 Raid 设置，我自己在使用 Linux 时遇到了错误。
确保它不是您的电缆 eSATA。
