EXT4-fs (nvme1n1p1)：以有序数据模式挂载的文件系统。选项：（空）

  • 772

我只想将我的 nvme-ssd 挂载到/mnt/ssd-high-NVMe

$ sudo rm -rf /mnt/ssd-high-NVMe
$ sudo rm -rf /mnt/ssd-high-NVME

$ sudo mkdir /mnt/ssd-high-NVMe
$ sudo mkdir /mnt/ssd-high-NVME

$ ls -lh

  drwxr-xr-x 2 root root 4.0K  Jan 20 22:42 ssd-high-NVME

$ sudo mount /dev/nvme1n1p1 /mnt/ssd-high-NVMe

但是，当我将挂载点更改为另一个目录（将“ssd-high-NVMe”设置为“ssd-high-NVME”）时，一切正常。

$ sudo mount /dev/nvme1n1p1 /mnt/ssd-high-NVME

$ df -h
  tmpfs           6.3G  2.3M  6.3G    1% /run
  /dev/sdb3       110G   45G   59G   44% /
  tmpfs            32G   95M   32G    1% /dev/shm
  tmpfs           5.0M  4.0K  5.0M    1% /run/lock
  tmpfs           4.0M     0  4.0M    0% /sys/fs/cgroup
  /dev/sdb2       512M  7.8M  505M    2% /boot/efi
  tmpfs           6.3G  180K  6.3G    1% /run/user/1000
  /dev/nvme1n1p1  458G  126G  312G   29% /mnt/ssd-high-NVME  <------ SUCCESS！

有一件事可能很重要：我以前曾用作/mnt/ssd-high-NVMe挂载点/dev/nvme1n1p1，并且我在原始文件上做了一些坏事，/dev/nvme1n1p1并在它仍然挂载时使其损坏。之后，我完全重新格式化/dev/nvme1n1p1（我确信磁盘是健康的）。我认为我的问题与此有关。但是如何解决呢？我应该进一步提供什么信息？

谢谢！

    TLDR；一个简单的systemctl daemon-reload后跟mount -a应该解决这个问题。

    应该存在一个名为mnt-ssd\x2dhigh\x2dNVME.mount（来自您的路径）\x2d的systemd 挂载-，您可以检查它：

    # systemctl status mnt-ssd\x2dhigh\x2dNVME.mount
● mnt-ssd\x2dhigh\x2dNVME.mount - /mnt/ssd-high-NVMe
   Loaded: loaded (/etc/fstab; generated)
   Active: inactive (dead) since Thu 2021-08-12 09:00:04 CEST; 49s ago
    Where: /mnt/ssd-high-NVMe
     What: /dev/disk/by-uuid/UUID_OF_OLD_DISK
     Docs: man:fstab(5)
           man:systemd-fstab-generator(8)

    这里重要的部分是What，它可能会显示旧磁盘的 UID。

    我假设在卸载旧 nvme 磁盘和安装新磁盘之间没有重新启动，因为服务应该在重新启动时重新生成。

    问题是 systemd-mount - 出于某种我不知道的原因 - 似乎强制使用安装定义中定义的磁盘，即使使用了显式mount DISK PATH。

    在我的情况下，我最初能够安装新磁盘，并且只有在我（热）将旧磁盘与 vm 分离后，我才能再安装任何其他磁盘。当我分离旧磁盘时，它甚至会自动从挂载点卸载新磁盘。

    我认为这是与手册的兼容性错误(u-)mount。Systemd 可能会看到旧磁盘被删除 - 它仍在 systemd-mount 中 - 将安装点标记为失败（或至少为非活动）并进行一些清理，包括确保不再在该路径上安装任何东西或类似的东西. 我不清楚之后无法安装另一个磁盘的原因。
