恢复 LUKS 解密过程

我使用以下命令运行了就地解密过程

sudo cryptsetup-reencrypt --decrypt /dev/sdb1

但被中断了（硬盘意外断开）

有没有办法恢复这个过程，还是我应该和我的数据说再见？

更多信息

我能够从大约0.1％photorec我猜想这是迄今为止解密的硬盘部分。

~/我在我的目录中发现了三个文件

4.0K -rw------- 1 root root  512 Oct 14 14:45 LUKS-688fbce2-bbe8-4665-aa40-dcf0e700ffea.log
1.1M -rw------- 1 root root 1.1M Oct 14 13:18 LUKS-688fbce2-bbe8-4665-aa40-dcf0e700ffea.new
1.1M -r-------- 1 root root 1.1M Oct 14 13:18 LUKS-688fbce2-bbe8-4665-aa40-dcf0e700ffea.org

.log文件内容

# LUKS reencryption log, DO NOT EDIT OR DELETE.
version = 2
UUID = 688fbce2-bbe8-4665-aa40-dcf0e700ffea
direction = 0

offset = 18014535680
shift = 0
# EOF

当我尝试解锁设备时

$ cryptsetup luksOpen /dev/sdb1 hdd
Reduced data offset is allowed only for detached LUKS header.

cryptsetup-reencrypt --decrypt当我再次尝试奔跑

$ cryptsetup-reencrypt --decrypt /dev/sdb1
Enter any existing passphrase: 
No key available with this passphrase.

您还能读懂标题吗？

$ cryptsetup luksDump /dev/sdb1
