在没有格式化的情况下运行LUKS重新加密时出错

Question

我无法运行luks再加密。我有关于/dev/sdc1的数据，并且不需要格式化就想加密它。我正在尝试利用luks2在线加密功能。

mathew@plug:/mnt $ sudo cryptsetup reencrypt --new --reduce-device-size 16M /dev/sdc1

正如本文档中所指定的- https://wiki.archlinux.org/index.php/Dm-crypt/Device_encryption#Cryptsetup_用法，我也尝试过，但仍然得到了错误：

我参考了这里的手册- https://man.cx/cryptsetup(8)

我的cryptsetup版本是2.1.0，在尝试apt-get install或apt-get upgrade时没有看到任何升级。

我困惑和困住了：

Answer 1

我终于从源代码中编译出来了，它起了作用。
