我有 2 个驱动器损坏,现在用 RAID 0 上的新驱动器替换。安装新驱动器后,我通过 USB 连接了 2 个损坏的旧驱动器以从中检索数据。这 2 个驱动器是构建 RAID 0 并使用 LVM,服务器现在可以识别这两个驱动器但 ind

我正在尝试安装驱动器,但它不工作
mount /dev/sdc1 /mnt/sdc1 -t ntfs
NTFS signature is missing.
Failed to mount '/dev/sdc1': Invalid argument
The device '/dev/sdc1' doesn't seem to have a valid NTFS.
Maybe the wrong device is used? Or the whole disk instead of a
partition (e.g. /dev/sda, not /dev/sda1)? Or the other way around?
mount /dev/sdd1 /mnt/sdd1
mount: wrong fs type, bad option, bad superblock on /dev/sdd1,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so
dmesg | tail -l
EXT4-fs (sdd1): bad geometry: block count 157286400 exceeds size of device (122096390 blocks)
有没有办法安装这两个驱动器而不会丢失数据并覆盖 RAID 或 LVM 配置?
sfdisk -d /dev/sdx >sdx.txt
cat sdx.txt
sfdisk /dev/sdx <sdx.txt
这会有帮助吗?
我的输出是

RAID0 不是 RAID...(意味着不是冗余的)RAID0 只是一种使用两个磁盘来大幅提高性能的方法。但是,它不允许您从故障驱动器中恢复。如果其中一个或两个都已损坏...在修复损坏之前(如果可能),您可能无法安装它们。如果您能够从磁盘读取...您可以尝试使用 mdadm 实用程序手动重新组装 RAID。
