升级至 24.10 后无法交换

8

我全新安装了 Ubuntu 24.04，其中有 ZFS 和由 Ubuntu 安装程序自动创建的 8GB 交换分区，如下所示/dev/nvme0n1p3。

我升级到 24.10，重启后交换分区不可用。似乎swapon找不到加密分区。升级过程中出了什么问题？

/etc/fstab自全新安装以来，我的未经修改：

# /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>

/dev/disk/by-uuid/6DA7-371B /boot/efi vfat defaults 0 1

还有我的/etc/crypttab：

dm_crypt-0 PARTUUID=d5018485-33be-40b8-80a1-9adb3c96ff16 /dev/urandom swap,initramfs

我尝试用/etc/crypttab替换 ID ，但重启后问题仍未解决。PARTUUID=d5018485-33be-40b8-80a1-9adb3c96ff16/dev/nvme0n1p3

我还尝试添加以下选项： swap,initramfs,plain,cipher=aes-xts-plain64,size=256

在 /etc/fstab 中，“/dev/disk/by-uuid/”和“UUID=”有什么区别？

14

我添加了 3 个要在启动时挂载的分区，但我在其他地方找到的有关新 fstab 语法的建议只与我的 fstab 中现有的两种样式之一一致，这让我非常困惑。我在其他地方找到的建议是，

Entry in /etc/fstab:
<UUID> <mount directory> <FS type> <mount options> <dump> <pass>
Example:
UUID=5caaee32-c3d3-429e-bad7-2898cf923805  /data  ext4  defaults 0 0

但是我的 /etc/fstab 的内容显示，

# <file system> <mount point>   <type>  <options>       <dump>  <pass>
/dev/disk/by-uuid/42301925-9786-4ab8-b56c-a3252accf5ef / ext4 defaults 0 1
/dev/disk/by-uuid/F759-075A /boot/efi vfat defaults 0 1
/dev/disk/by-uuid/df063034-c8da-4f14-b1c8-52cdccecc06f /tmp ext4 defaults 0 2
UUID=da0ad11a-8fd7-431a-a49a-d883037aa2c8 /LamaSpace ext4 defaults 0 2
/dev/disk/by-uuid/4acdc978-c30b-4b3f-bbf6-0b7b99094463 /home ext4 defaults 0 2

请注意，只有我的 /LamaSpace 分区使用上面给出的语法；其他分区使用 /dev/disk/by-uuid/ ... 其他语法相同。这两个习语是等效的吗？

额外信息：我使用的是 Ubuntu 24.04。我的所有分区都在一个 8 TB Barracuda HDD 中：

（我的三个新分区是 sda6、sda8 和 sda9，我手动挂载了它们，但尚未出现在 /etc/fstab 中。）

升级到 24.04 LTS 后自动挂载不起作用

5

我昨天刚刚从 22.04 LTS 升级到 24.04.1 LTS

我遇到的问题是它不再自动挂载网络驱动器。手动挂载可以正常工作。

在我的记录中/etc/fstab我有如下记录：

10.0.0.12:/Documents  /mnt/Documents  nfs auto,nofail,noatime,nolock,intr,tcp,actimeo=1800 0 0
10.0.0.12:/Pictures   /mnt/Pictures   nfs auto,nofail,noatime,nolock,intr,tcp,actimeo=1800 0 0

重启后这些挂载点没有被挂载，但是mount /mnt/Documents可以按预期工作。

在哪里查找？如何修复？

Ubuntu 在启动时不挂载分区（fstab 看起来很奇怪）

6

我整晚都在尝试不同的解决方案，但没有任何效果（磁盘、手动更改等）。

这是在我调整 gparted 上的 sda1 分区大小之后发生的。

首先，这是我的 fstab 现在的样子：

tmpfs /tmp tmpfs nosuid,nodev 0 0
/dev/sda1 /mnt/sda1 auto nosuid,nodev,nofail,x-gvfs-show 0 0
/dev/sda3 /mnt/sda3 auto nosuid,nodev,nofail,x-gvfs-show 0 0

我将它设置在磁盘上以安装它，但它无法启动。

这是我验证时得到的错误：

   [W] recommended root FS passno is 1 (current is 0)
/mnt/d22c5008-1a64-4577-8eb7-e760f2f88326
   [E] cannot detect on-disk filesystem type
/mnt/4480B15780B14FE2
   [E] cannot detect on-disk filesystem type

由于磁盘不工作，我怎样才能永久挂载这些分区？我见过不同的 fstab 格式，但我的看起来完全不同。

这是来自 gparted 的 ss。

通过 /etc/fstab 中的条目从 NTFS 驱动器挂载子文件夹

1

我有一个 NTFS 硬盘驱动器连接到我的 Raspberry Pi。驱动结构如下：

F:\
- Images
- Other
- Movie

我只想以只读方式挂载 /mnt/disk/Movie 中的 F:\Movie 文件夹。

我的 fstab 看起来像：

UUID=(lots of letters and numbers) Movie /mnt/disk/Movie   ntfs   defaults,uid=0,gid=0,fmask=0022,dmask=0022,noatime,nofail,x-systemd.device-timeout=2

但它不起作用。我究竟做错了什么？

GUI Disks 实用程序添加的 fstab 条目似乎格式错误但有效？

2

磁盘实用程序 ( gnome-disks) 在以下位置添加了此条目/etc/fstab：

UUID=[UUID] [mount pount] auto nosuid,nodev,nofail,x-gvfs-show 0 0

基于大量示例和info fstab，auto是文件系统类型（在本例中为 ext4 ）应该在的位置，然后auto,用逗号开始选项列表。

但是分区是在启动时安装的，所以auto工作正常。fstab格式松懈吗？磁盘实用程序在格式化方面是否草率？

（为什么我关心：我即将在一个新的硬件系统上安装 Ubuntu 服务器，并想fstab手动添加一个适当的条目。）

如何为多个用户挂载 SMB 共享

0

我有一个专有的 NAS 服务器，而不是提供 SMB 服务来访问其内容。SMB 协议坚持 V1.0（无法更改）。

我还有一个 ubuntu 20.04 服务器，应该可以访问这个 NAS。具体来说，我使用 NAS 来存储由 Synthing 服务编写的数据副本。也可以从 Windows 计算机访问相同的 NAS。

这是我的 fstab 条目：

//mynashost/SomeShare /mnt/SomeShare cifs    vers=1.0,guest,uid=1000,gid=1000,comment=cloudconfig,iocharset=utf8     0       0

这适用于我的主要用户（uid 1000 和 gid 1000），但不适用于其他用户。具体来说，我的 syncthing 服务正在使用专用用户帐户运行。

此其他用户能够读取内容，但无法写入（权限被拒绝）。

即使使用 sudo，尝试访问chown共享中的文件夹也不起作用（权限被拒绝）。

我对与安全相关的 fstab 选项感到非常困惑。如何修复我的选项，让我的服务器的任何用户读取和写入数据？

由于它是家庭服务器，我不需要隔离每个用户，如果有帮助，匿名安装 NAS 是一种选择。

fstab 自动创建挂载点

7

如此处所述，“您必须在挂载分区之前创建挂载点。” 但是在 fstab 中添加以下行并重新启动系统后

/dev/sdxy /media/user/hdd_mount_point ext4 defaults 0 0
tmpfs /mnt/tmpfs_mount_point tmpfs rw,nosuid,noatime,nodev,size=4G,mode=1777 0 0

挂载点（目标目录）hdd_mount_point，tmpfs_mount_point如果它们不存在则自动创建。我知道如果它不存在，您可以通过在其手册页中向命令添加X-mount.mkdir选项来创建挂载点，但我真的很想知道在通过 fstab 挂载文件系统时是否隐式使用此选项。mount

不，它不是自动将文件系统添加到 /etc/fstab的副本

mount ntfs 中的权限选项

0

我最近阅读了有关在 linux 中安装 NTFS 分区的答案，以便我可以更改文件和文件夹权限（chmod）。他们解释说我使用“权限”选项。例子：

# fstab
UUID=12102C02102CEB83 /mount_point  ntfs-3g  defaults,permissions 0 0

# manual
sudo mount /dev/sdax -t ntfs-3g -o permissions /mount_point

并且有效，但是我检查了man fstab和man mount并且找不到“权限”选项。网上搜了一下，很少有地方提到，但没有链接到来源

有人能告诉我这个选项来自哪里吗？（提供解释此选项的官方链接）。谢谢

升级至 24.10 后无法交换

在 /etc/fstab 中，“/dev/disk/by-uuid/”和“UUID=”有什么区别？

升级到 24.04 LTS 后自动挂载不起作用

从 23.04 升级到 ubuntu 23.10 后：警告！UUID=xxxx 不存在。掉落到贝壳里！
