请考虑之前的讨论作为这个新问题的背景。
我修改了我的脚本，并将相同的文件系统选项应用到我的 USB 驱动器的 ext4 分区，使用调2fs，以及 fstab 中指定的挂载选项。
这些选项与之前的讨论相同。我已应用这些更改并重新启动，但是山命令没有报告我所期望的内容，即它会显示类似于内部硬盘驱动器分区报告的安装选项。报道内容如下：
/dev/sdc3 on /site/DB005_F1 type ext4 (rw,relatime)
/dev/sdc4 on /site/DB005_F2 type ext4 (rw,relatime)
/dev/sdc5 on /site/DB005_F3 type ext4 (rw,relatime)
/dev/sdc6 on /site/DB005_F4 type ext4 (rw,relatime)
/dev/sdc7 on /site/DB005_F5 type ext4 (rw,relatime)
/dev/sdc8 on /site/DB005_F6 type ext4 (rw,relatime)
/dev/sdc9 on /site/DB005_F7 type ext4 (rw,relatime)
/dev/sdc10 on /site/DB005_F8 type ext4 (rw,relatime)
/dev/sdc11 on /site/DB006_F1 type ext4 (rw,relatime)
/dev/sdc12 on /site/DB006_F2 type ext4 (rw,relatime)
/dev/sdc13 on /site/DB006_F3 type ext4 (rw,relatime)
/dev/sdc14 on /site/DB006_F4 type ext4 (rw,relatime)
/dev/sdc15 on /site/DB006_F5 type ext4 (rw,relatime)
/dev/sdc16 on /site/DB006_F6 type ext4 (rw,relatime)
/dev/sdc17 on /site/DB006_F7 type ext4 (rw,relatime)
/dev/sdc18 on /site/DB006_F8 type ext4 (rw,relatime)
这些都报告相同，但只报告“rw，relatime”，而我期望更多。
完整的转储2fs第一个 USB 分区的报告（与所有其他分区相同）如下：

有谁知道为什么会发生这种情况？
可以采取什么措施让内部硬盘和 USB 硬盘报告相同的选项吗？
在我的/etc/default/中幼虫文件中，我目前使用以下涉及的定义怪癖：
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash scsi_mod.use_blk_mq=1 usb-storage.quirks=1058:25ee:u ipv6.disable=1"
我是否需要指定另一个怪癖才能使日志记录和挂载选项按预期生效？或者这又是一个“一切都好“情况和其他帖子一样吗？

答案1
如果在 中指定，某些 ext4 文件系统选项可能不会生效，/etc/fstab因为它们需要更改文件系统结构。其中一些可以在卸载文件系统时简单地应用tune2fs，但有些选项可能需要在之后运行完整的文件系统检查tune2fs才能正确生效。
据我所知，没有任何机制会根据磁盘是否通过 USB 连接来影响文件系统选项。
