无法在 bash 中挂载 USB 驱动器（ubuntu 服务器）

我无法在 bash 中安装我的 USB 驱动器。首先，我使用 parted 对其进行了格式化：

GNU Parted 3.2
Using /dev/sdc
Welcome to GNU Parted! Type 'help' to view a list of commands.
(parted) mkpart
Partition name?  []? backup
File system type?  [ext2]? ext4
Start? 1m
End? 100%
(parted) q

然后，我获取了分区的 UUID：

sudo blkid /dev/sdc1
/dev/sdc1: PARTLABEL="backup" PARTUUID="29e0527b-b182-46ff-b8d4-b457f2cbd19c"

接下来，我将 PARTUUID 放入 /etc/fstab：

# /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).
#
# <file system> <mount point>   <type>  <options>       <dump>  <pass>
# / was on /dev/nvme0n1p1 during installation
UUID=96a4c1cc-8681-45a9-b3f7-634803e2c6fa /               ext4    errors=remount-ro 0       1
UUID=29e0527b-b182-46ff-b8d4-b457f2cbd19c /media/backup1        ext4    noauto,defaults 0       2

到目前为止一切顺利。但是，安装不起作用：

sudo mount /media/backup1
mount: can't find UUID=29e0527b-b182-46ff-b8d4-b457f2cbd19c

因此，mount 似乎找不到此 UUID。但它在那里，我仍然可以使用 查询它sudo blkid /dev/sdc1。此外，sudo fdisk -l似乎也找到了它：

sudo fdisk -l

[...]

我注意到一件有趣的事情是，该条目不在，blkid而仅在sudo blkid：

blkid
/dev/nvme0n1p1: UUID="96a4c1cc-8681-45a9-b3f7-634803e2c6fa" TYPE="ext4" PARTUUID="d02d7331-01"

sudo blkid
/dev/nvme0n1p1: UUID="96a4c1cc-8681-45a9-b3f7-634803e2c6fa" TYPE="ext4" PARTUUID="d02d7331-01"

/dev/sda1: LABEL="datapool" UUID="7111675423553490798" UUID_SUB="11975018375513471305" TYPE="zfs_member" PARTLABEL="zfs-ab8eb30bd084e717" PARTUUID="d29dadab-f6e7-dd4a-b7d6-442544920142"
/dev/sda9: PARTUUID="403ede0a-5e26-4244-8a0c-5de2f00e2526"

/dev/sdb9: PARTUUID="91eb1b79-fc3d-6847-9b52-c2f46d04b7c6"
/dev/sdc1: PARTLABEL="backup" PARTUUID="29e0527b-b182-46ff-b8d4-b457f2cbd19c"

更新：PARTUUID=好的，现在我设法通过使用而不是 来摆脱上述错误UUID=。但是，现在我收到以下错误：

sudo mount /media/backup1/
mount: wrong fs type, bad option, bad superblock on /dev/sdc1,
       missing codepage or helper program, or other error

       In some cases useful info is found in syslog - try
       dmesg | tail or so.

的输出dmesg | tail如下：

[ 3349.566573] EXT4-fs (sdc1): VFS: Can't find ext4 filesystem

现在有什么问题？

答案1

自从您对驱动器进行分区并创建文件系统以来，您是否断开/重新连接了 USB 驱动器或重新启动了机器？如果没有，请运行

sudo partprobe /dev/sdc

告诉内核更新有关驱动器上的分区表和文件系统 UUID 的信息。
