安装未安装磁盘的现有分区

我运行了该fdisk -l命令来显示所有磁盘和分区。以下是输出：

目前我挂载的分区是/dev/sdb1和 。我想访问/dev/sdb2分区上有一些数据。我该如何临时挂载它以便可以访问它？运行时出现错误，提示。/dev/sda2mount /dev/sda2mount: can't find /dev/sda2 in /etc/fstab or /etc/mtab

答案1

/dev/sda2是个 ”扩展“包含 的分区/dev/sda5。该分区中没有数据（除了 的内容以外/dev/sda5）。

不过，一般情况下，如果您没有包含/etc/fstab挂载选项的条目，则需要提供所有要挂载的选项：

mount /dev/something /some/directory/to/mount/to

可能是因为-t filesystemtypemount 无法自动检测到它。
