Ubuntu Desktop 14.04 中的新驱动器

Ubuntu Desktop 14.04 中的新驱动器

我正在使用一个新硬盘(非 SSD,普通旧硬盘),它已经是 ext4 格式,并按照以下步骤安装在 /media/mynewdrive 上。文章

但我想将其安装在 /opt 上,因为大多数软件都安装在那里。目前我需要手动将内容移动到 /media/mynewdrive 及其下方...位置不太方便记住....我该怎么办?我的旧驱动器中已经有 /opt 和子目录,我想保留它们。这是我当前的 mount 命令输出:

它是 Windows 10 的双启动系统,我不想影响任何其他东西。

在与我认识的一些 Linux 专家交谈后,我发现了一些可能的选择:

  1. 我可以使用 LVM,它允许将新的物理磁盘和物理卷(分区)添加到逻辑卷(已挂载的分区),现有的逻辑卷(比如/opt)可以使用新物理卷提供的额外空间进行扩展。
  2. 另一个选择是我的//media/mynewdrive都是类型ext4我可以将所有内容复制到新分区(安装为的分区/media/mynewdrive),然后将其安装为/opt

寻找一些选项并将选择最能满足我需求的选项。
