我的 CentOS 机器上的根硬盘空间有问题。
df -h 返回

tmpfs 26G 72K 26G 1% /run/user/1001
然而,磁盘应用程序的屏幕截图显示我有额外的(未安装的?)驱动器:
当我尝试格式化 8.0 TB 硬盘并尝试安装它时,CentOS 警告我该卷上的所有数据都将丢失 - 我不想丢失系统上的任何文件,因此对此不确定。
如何增加根目录的大小以及如何访问磁盘 GUI 中显示的 1TB 和 8TB 存储而不会有丢失文件的风险?

答案1
根据评论,你似乎还有另一个PV(如果那里没有信息)你可以添加到 VG:
vgextend cl /dev/sda3
之后您可以扩展 LV:
lvextend -L+2GB /dev/mapper/cl-root
(这会为root
文件系统添加 2GB)
然后扩展root
文件系统。该命令取决于您使用的文件系统
