我看过一些磁盘格式化/分区讨论，其中提到将销毁现有 GPT/MBR 数据结构作为第一步：

sgdisk --zap-all /dev/nvme0n1

我以前没有意识到这一点，当我设置磁盘时，我通常使用：

parted --script --align optimal  \
    /dev/nvme0n1 --              \
    mklabel gpt                  \
    mkpart ESP fat32 1MiB 512MiB \
    set 1 boot on                \
    name 1 boot                  \
    mkpart primary 512MiB 100%   \
    set 2 lvm on                 \
    name 2 primary

我应该先把东西清理掉（例如sgdisk --zap-all）吗？不这样做的缺点是什么？

我使用 dd 将较小的磁盘克隆到较大的磁盘上，但是现在启动时出现以下 dmesg 错误：

[Fri Sep 30 11:48:43 2022] GPT:Primary header thinks Alt. header is not at the end of the disk.
[Fri Sep 30 11:48:43 2022] GPT:1953525167 != 3907029167

[Fri Sep 30 11:48:43 2022] GPT: Use GNU Parted to correct GPT errors.

我该如何解决这个问题？该错误表明使用parted，但我不确定要运行哪些命令？

我有一个驱动器发生故障的池，zfs 对此很愚蠢。我添加了一个最终进入 /dev/sdl 的磁盘，我使用该磁盘按 id 将其添加进去，由于在另一个驱动器在重新启动期间或之前发生故障之后，我得到以下行。

5642991870772164099 不可用 0 0 0 是 /dev/sdl1
知道如何获取信息以找到 5642991870772164099 的序列号是什么吗？

我在笔记本电脑上使用的是 Windows 11，但我想在旁边安装一个 Linux 发行版。因此，我缩小了 30GB 的 OS 磁盘并安装了 Pop_Os。在安装过程中，我创建了 EFI 和根分区。

我现在想扩展 ext4 分区。我能够进一步缩小原始 OS 磁盘，但是使用 gParted 时未分配的空间显示在左侧，我无法调整根分区的大小。

在 gparted 屏幕截图和 fdisk 输出下方：

刚刚注意到我正在使用 SDD 作为 SSD。已更正

我需要帮助解释这种情况。/dev/sda是备份的数据磁盘并具有可重现的数据，因此这不是系统关键，但我想避免恢复/重建数据的工作，其中一些将非常耗时

是否可以恢复/修复？

如果有怎么办？如果我擦除磁盘以重新使用它的可靠性是什么？

摘要（详细报告如下）：

  • 不会安装：坏超级块
  • badblocks 没有发现坏块
  • smartctl 没有报错
  • fsck 无法设置超级块标志
  • fdisk 显示干净的分区
  • dmesg 显示写入错误
  • parted 显示 792 GB 可用 1 TB 驱动器

挂载 ssd 失败，如下所示：

 [[email protected] ~]$ sudo mount /dev/sda1 /mnt/sda
 mount: /mnt/sda: can't read superblock on /dev/sda1.
        dmesg(1) may have more information after failed mount system call.
 [[email protected] ~]$

但 badblocks 没有发现坏块

但是 smartctl 没有发现错误

对于每个多路径磁盘标签，/dev/mapper我最后都有另一个带有 1 的标签。他们是一样的吗？有什么关系吗？

例如：

/dev/mapper/mpathaj和/dev/mapper/mpathaj1 或 /dev/mapper/mpathai和/dev/mapper/mpathai1

当我发出命令od --read-bytes=128 --format=c /dev/mapper/mpathai时，磁盘看起来很干净：

[[email protected] ~]# od --read-bytes=128 --format=c /dev/mapper/mpathai
0000000  \0  \0  \0  \0  \0  \0  \0  \0  \0  \0  \0  \0  \0  \0  \0  \0
*
0000200

但最后 1 的另一个显示一些行：

[[email protected] ~]# od --read-bytes=128 --format=c /dev/mapper/mpathai1
0000000 001 202 001 001  \0  \0  \0  \0 003  \0  \0 200 220   .   5 213
0000020  \0  \0  \0  \0  \0  \0  \0  \0  \0  \0  \0  \0  \0  \0  \0  \0
0000120   3  \0  \0  \0  \0  \0  \0  \0  \0  \0  \0  \0  \0  \0  \0  \0
   some characters I needed to remove to don't show costumer content.
0000160  \0  \0  \0  \0  \0  \0  \0  \0  \0  \0  \0  \0  \0  \0  \0  \0
0000200

这发生在每个磁盘上。一个是干净的，另一个没有。

而且，我问它的原因是：我可以失去一个（mpathaj）而不会失去另一个（mpathaj1）吗？我已经看到他们指向不同的/dev/dm-xx.

即：/dev/mapper/mpathaj是/dev/dm-18和/dev/mapper/mpathaj1是/dev/dm-19

我最终遇到了将磁盘空间减半的情况，并希望将两个分区合并在一起。这是来自 Gnome Disks 的图片：

在此处输入图像描述

左侧的蓝色分区未使用，右侧的分区 7 是我启动并当前使用的分区。看起来在 Gnome Disks 中，我只需单击红色减号即可删除蓝色的未挂载分区。这会让我合并我的两个分区吗？

谢谢。

我有一个旧的 Seagate 4TB 内置驱动器，来自一台破旧的电脑，我计划将其重新用作游戏的备用驱动器。

为了安全起见，我想我会先对其进行一些 smartctl 扫描，所以我做smartctl -t short /dev/sdb了并得到了结果。他们看起来不错，因为我没有看到“WHEN_FAILED”列中列出的任何内容（最初我主要关心与温度相关的错误）。但后来我看到2018 年的一篇文章 提到“Current_Pending_Sector”非常严重......而且我的不是零......而且我确实有一些错误......因为我真的无法理解是否要担心他们，我想我会尝试 SE。

到目前为止，我最好的猜测是我不应该在上面放任何重要的东西，但是如果我对保存文件夹进行符号链接以便它们存在于其他地方（在具有更好智能结果的驱动器上）并且不如果驱动器发生故障，请注意重新下载已安装的游戏。也不确定“READ DMA EXT”错误是否表明即将发生故障，或者这可能是电缆或其他一次性事件（我只能看到错误 35-39，它们都发生在“16936 小时”......不确定是否有办法查看所有错误，或者是否像它说的那样只存储最后 5 个错误）。OTOH，我在安装它或从中复制数据时没有任何问题（这是一个亲戚，他们不再想要它；只是一些图片/视频）。

如果驱动器可能还有一些生命，至少有相当大的可能性，我不介意将它用于不太重要的东西。但它很可能在不久的将来失败，我宁愿不要浪费任何时间来购买新的磁铁:-) 有什么建议/建议吗？

无论如何，我smartctl -t long /dev/sdb等到第二天再跑smartctl -a /dev/sdb。以下是结果：
