VMware ESXi 中的 linux 虚拟机硬盘扩容

注意：
以下操作可能会丢失数据，应该先备份数据。

1. 把虚拟机关机
2. 在 esxi 中增加硬盘容量
3. 把虚拟机开机
4. 使用 fdisk -l 查看硬盘大小
   
5. 执行 fdisk /dev/sda，进行操作，使用 p 查看分区详情、使用 d 删除当前分区、使用 n 新建分区、使用 w 保存分区设置。具体过程如下：

   fdisk /dev/sda
    
   Welcome to fdisk (util-linux 2.38.1).
   Changes will remain in memory only, until you decide to write them.
   Be careful before using the write command.
    
   This disk is currently in use - repartitioning is probably a bad idea.
   It's recommended to umount all file systems, and swapoff all swap
   partitions on this disk.
    
    
   Command (m for help): p
    
   Disk /dev/sda: 64 GiB, 68719476736 bytes, 134217728 sectors
   Disk model: Virtual disk
   Units: sectors of 1 * 512 = 512 bytes
   Sector size (logical/physical): 512 bytes / 512 bytes
   I/O size (minimum/optimal): 512 bytes / 512 bytes
   Disklabel type: dos
   Disk identifier: 0xfe21000f
    
   Device     Boot Start      End  Sectors Size Id Type
   /dev/sda1        2048 33554431 33552384  16G 83 Linux
    
   Command (m for help): d
   Selected partition 1
   Partition 1 has been deleted.
    
   Command (m for help): n
   Partition type
      p   primary (0 primary, 0 extended, 4 free)
      e   extended (container for logical partitions)
   Select (default p):
    
   Using default response p.
   Partition number (1-4, default 1):
   First sector (2048-134217727, default 2048):
   Last sector, +/-sectors or +/-size{K,M,G,T,P} (2048-134217727, default 134217727):
    
   Created a new partition 1 of type 'Linux' and of size 64 GiB.
   Partition #1 contains a ext4 signature.
    
   Do you want to remove the signature? [Y]es/[N]o: y
    
   The signature will be removed by a write command.
    
   Command (m for help): w
   The partition table has been altered.
   Syncing disks.

6. 使用 resize2fs /dev/sda1 扩展文件系统为分区大小
