首先，我想让你知道我来这里是因为我正在寻找一个解决方案或一种能够安装 HOME 分区并读取内部数据的方法。
我一直在运行 Funtoo GNU/LinuxRAID 0 假阵列自从我 2010 年购买这台电脑以来，大约。
昨天启动进入系统救援并尝试格式化每个分区除了首页部分。我认为格式化时出了问题，因为我突然开始遇到以下问题。
dmraid -ay

ls /dev/mapper/

isw_bggjiidefd_240GB_BX100v2_5 isw_bggjiidefd_240GB_BX100v2_5p2 isw_cfccfdiidi_640GB_RAID0
在之前的方案和目录中，扩展分区内的逻辑分区丢失。

现在，使用 mdadm而不是 dmraid 假 RAID 工具。
通过组装数组米达德姆我可以看到每个块设备，但无法挂载 HOME 分区/dev/md/240GB_BX100v2.5_0p9。我可以将其他分区挂载在扩展分区下，因为我在 mdadm 组装时格式化了它们。
mdadm --examine --scan
