我想要挂载snb1到/volume2。
/volume2存在并且所有权限都设置正确。
bin boot cdrom dev etc home lib lib32 lib64 libx32 lost+found media mnt opt p path proc pvolume1 root run sbin snap srv swap.img sys tmp usr var volume1 volume2
首先我检查一下支架：
lsblk -l

sdb 8:16 0 3.7T 0 disk
sdb1 8:17 0 3.7T 0 part
sdb1未安装，并且 中没有安装任何其他内容/volume2。因此我继续将 sdb1 安装到 /volume2
sudo mount /dev/sdb1 /volume2。我没有收到任何错误消息。
但当我再次检查时：
lsblk -ls

我遇到了同样的问题。sdb1 只是 mot 挂载。我以为可以通过重启来解决这个问题。但它不起作用。这是为什么？
编辑：我刚刚尝试过：
sudo mount -a /dev/sdb1 /volume2。我现在得到：
mount: /volume2: special device /dev/disk/by-uuid/dace6e49-5297-4a1a-8517-0e4fce045ce4 does not exist.

答案1
因此情况是，当在 UEFI 菜单中为安装 Linux 选择 USB 驱动器时，它首先向我显示 BIOS 安装。UEFI 安装是下拉菜单中的下一个。我没有检查这一点，而是在 BIOS 模式下安装了 Ubuntu 服务器。由于不知道该错误，我将所有启动分区都设为 UEFI。然后，在我的特定安装中，这些分区不被识别为有效启动分区。因此，每次重新启动时，我都必须在 UEFI 中手动选择正确的硬盘驱动器。我进行了彻底的重新安装以修复它。
