oracle virtualbox 扩大虚拟机硬盘
调整分配的disk大小
cd D:\Oracle\VirtualBox\
D:
VBoxManage.exe list hdds
VBoxManage.exe modifyhd 2e8d53da-8f90-410f-bd1c-19c4798afab8 --resize 51200
这时在操作系统层面已经看到扩容后的硬盘大小,但是并没有分配给/dev/sda2使用。
[root@node1 ~]# fdisk -l
Disk /dev/sda: 53.7 GB, 53687091200 bytes, 104857600 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes

创建/dev/sda3,然后加到 /dev/sda2 所在的vg里
