如题，raid 1，折腾姿势不对，2块盘都不同程度出现问题，一块完全挂了，一块只是系统区不正常。
在Ubuntu下，用mdadm -Asf && vgchange -ay复制代码
命令后，提示错误：no suitable driver found for /dev/md3
/dev/md3 指向的就是阵列。
重要资料啊，亲们，拜谢！

我可不可以用一块同容量的盘，全盘复制，勉强也算是raid1了呢，虽然我也知道，2块盘肯定不会是完全一样，病急乱想办法
评论
Ubuntu下工具不懂。
但是如果是raid 1的话， 挂到别的机子上应该是直接认盘的啊。
评论
就是挂在另一台上也不认了，需要重装系统才行，重装就提示全盘抹掉，没敢继续。

在线等，挺急的，混乱了

你放到另外一台已经有系统的Win的电脑上，在win下看能否看到硬盘，如果能看到的话，就可以恢复资料。
不要做系统盘，也不要安装操作系统。 然后可以用一些恢复软件扫一下。比如easyrecovery，geniusdrive等等。
我以前也是有个Raid 1的硬盘，已经升级替换下来了，后来新的硬盘中毒了。后来单盘从raid 1的盘中也把数据恢复了。但是我的win的格式。在win的系统下恢复，比较简单些。

磁盘管理里面现在又dev/md3不
有的话
sudo mkdir /tmp/raid
sudo mount /dev/md3 /tmp/raid复制代码
看看能不能挂载到/tmp/raid目录
cd /tmp/raid
ls *复制代码

有的，我再试试您的这个

sudo mdadm --stop /dev/md3

sudo mdadm --verbose --assemble --force /dev/md3 /dev/sdb3复制代码
第二行估计会提示

先试试吧 md3出来后再试试刚才的mount命令
