如何增加精简配置虚拟机的硬盘空间？

创建了具有 100 GB 硬盘的精简配置 VM (Suse Linux)。现在由于空间要求，我需要将大小增加到 200GB。有人能告诉我如何增加“/”目录的空间吗？

Below is the output of the df -h command.

Filesystem      Size  Used Avail Use% Mounted on
devtmpfs        4.0M     0  4.0M   0% /dev
tmpfs            12G  8.0K   12G   1% /dev/shm
tmpfs           4.7G   18M  4.7G   1% /run
tmpfs           4.0M     0  4.0M   0% /sys/fs/cgroup

/dev/sda1       511M  4.9M  507M   1% /boot/efi

tmpfs           2.4G   40K  2.4G   1% /run/user/465
tmpfs           2.4G   44K  2.4G   1% /run/user/1000
tmpfs           2.4G   40K  2.4G   1% /run/user/0

Below is the output of the fdisk -l command.

Partition table entries are not in disk order.

我尝试使用以下命令修复分区并更正 GPT PMBR 大小不匹配，然后重新启动。系统重新启动正常。

Enter into the disk partition place: 
fdisk /dev/sda

Command (m for help):   m  
Command action
  ...
   l   list known partition types
   m   print this menu
   p   print the partition table
   q   quit without saving changes
   w   write table to disk and exit
   x   extra functionality (experts only)

Command (m for help):   x

Expert command (m for help):   m
Command action
...
   f   fix partition order
   m   print this menu
   p   print the partition table
   q   quit without saving changes
   r   return to main menu
   v   verify the partition table
   w   write table to disk and exit

Expert command (m for help):   f
Done.

The partition table has been altered!

我关闭了 SWAP 并删除了 SWAP 分区。然后我删除了“/”分区并重新创建了该分区，大小为 190G。

Commands used:

swapoff -a

fdisk  /dev/sda

由于“/”仍显示旧大小，我运行命令 xfs_growfs -d /。分区大小按预期增加。现在的问题是，我的系统无法以正常模式启动（只停留在 4 个点和蜥蜴标志上），而我可以启动到恢复模式。

我是否遗漏了什么？

答案1

问题已解决。“ / ”分区已扩展。但是，在完成所有活动后重新启动时，引导加载程序仍在尝试访问属于 SWAP 分区的旧 UUID。我更新了 UUID，它开始正常启动。

感谢大家的建议和支持。
