全新的硬盘驱动器 (/dev/sdb)。没有关于它的数据(可以尝试大多数事情)。Ubuntu 20.04。由于我的主驱动器是 SSD,我决定创建一个新的卷组 hdd-vg。我创建了 VG、LV 和 PG,看似成功(见下文),但每当我尝试挂载它或将其放入 fstab 时,都会出现错误。是不是需要格式化什么的?
# mount /dev/mapper/hdd--vg-hdd--lv1 /mnt/hdd
mount: /mnt/hdd: wrong fs type, bad option, bad superblock on /dev/mapper/hdd--vg-hdd--lv1, missing codepage or helper program, or other error.
# mount /dev/hdd-vg/hdd-lv1 /mnt/hdd
mount: /mnt/hdd: wrong fs type, bad option, bad superblock on /dev/mapper/hdd--vg-hdd--lv1, missing codepage or helper program, or other error.
在下面的数据中,我经常排除系统上其他驱动器/逻辑的信息。
