Raid1 失败 dev 不适合任何类型的阵列

您好，我正在尝试从磁盘 /dev/sdc /dev/sdd 创建 raid lv1。在快捷方式中我收到错误

  mdadm --create /dev/md0 --level=1 --raid-devices=2 /dev/sdc1 /dev/sdd1
  device /dev/sdc1 not suitable for any style of array

但在您向我发送其他类似主题的链接之前，请允许我解释一下我的问题。

fdisk -l

root@..:/# mount | grep sdc

root@..:/# mount | grep sdd

因此，我没有在任何地方安装我的磁盘，我还检查了没有其他 raid 安装：

root@...:/# mdadm --zero-superblock /dev/sdd1
mdadm: Unrecognised md component device - /dev/sdd1
root@...:/# mdadm --zero-superblock /dev/sdc1
mdadm: Unrecognised md component device - /dev/sdc1

所以现在我不知道该检查什么来诊断我的配置出了什么问题。我也重启了几次机器，也试过了 liveCD，所以现在我没主意了

答案1

答案是在创建分区期间我选择默认的扩展，为了强制 madm 工作，两个分区都必须是“Linux raid 自动检测”类型（fdisk 类型 fd）。

希望它能帮助有类似问题的人
