我刚刚在我的计算机上安装了 Ubuntu 和 Windows 双启动系统。
这是我的磁盘配置：
Disk /dev/sda: 931,5 GiB, 1000204886016 bytes, 1953525168 sectors
Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical):
512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes

我想将 /dev/sdb 镜像到 /dev/sda。
如何在不将 sdb2 重新格式化为 raid 的情况下进行设置？
