很久以前，我想为客人建立单独的分区，我发出了一些我不记得的命令，我想撤消更改，这是我迄今为止发现的

卸载重复分区是否安全？
sudo umount /media/hdd2/Gusts
答案1
如果我理解这个问题，您已经/dev/sdb1安装在两个位置：/media/hdd2和/media/hdd2/Gusts。您想要移除Gusts安装座。
卸载重复分区是否安全？
是的。该命令sudo umount /media/hdd2/Gusts将执行此操作。
但是，如果这是在启动时安装的，则安装将在您重新引导时返回。您可以通过编辑来删除启动时的安装/etc/fstab。将会出现类似于以下内容的行：
/dev/sdb1 /media/hdd2/Gusts ext4 defaults 0 0
为了防止将来安装时/media/hdd2/Gusts删除整条线。
