您好,我正在尝试安装一个新的逻辑卷。我在 ubuntu 服务器 13.04 上。我使用剩余的磁盘空间创建了 lv。我收到此错误:
NTFS signature is missing.
Failed to mount '/dev/mapper/TheServer--vg-lv_media': Invalid argument
The device '/dev/mapper/TheServer--vg-lv_media' 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?
我不确定为什么会发生这种情况。这是我的 LVM 设置列表:

我正在安装/media/store
这可能是一个问题,因为挂载点位于同一个 VG 中的另一个 LV 上?
答案1
仅创建分区并不能使其可用,必须在其上创建文件系统。您需要以与简单分区相同的方式对 LVM 分区进行创建。要使用的工具是带有mkfs
适当参数的。指定文件系统类型和设备名称就足够了。如果您想创建ext4
类型文件系统,可以使用以下命令:
sudo mkfs.ext4 /dev/TheServer-vg/lv_media
同样,ext4
如果您愿意,可以用其他文件系统类型替换,但[TAB]
密钥会像往常一样提供帮助。
