安装 raid1 驱动器失败，驱动器正忙或未找到分区

几年前我遇到过同样的问题安装：未知文件系统类型“linux_raid_member”。我想安装来自 raid 1 阵列的驱动器。我按照步骤操作，但mdadm --assemble --run --force /dev/md0 /dev/sda3 返回mdadm: cannot open device /dev/sda3: No such file or directory 当我尝试时，mdadm --assemble --run --force /dev/md0 /dev/sda3 它返回mdadm: /dev/sda is busy - skipping

fdisk -l有以下输出

我不知道为什么会有微软分区，因为我使用的是纯 Linux 操作系统。奇怪的是，我mdadm --examine /dev/sda为驱动器 sda 找到了有效的超级块，但为分区 sda3 却没有找到
