Proxmox 仮想マシンのデータを抽出するために LVM をマウントする際に問題が発生しています。マウント方法について何かアイデアはありますか?
データは2TBのハードドライブの1つに保存されています。RAID 1だと思います。
root@rescue:~# mount /dev/sdd /mnt/
mount: block device /dev/sdd is write-protected, mounting read-only
NTFS signature is missing.
Failed to mount '/dev/sdd': Invalid argument
The device '/dev/sdd' 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?
root@rescue:~# mount /dev/sdd1 /mnt/
