Virtualization VMware Virtual Machine expansion

Prerequisites:

1. Create a disk when creating a new virtual machine for example, after which the disk can be dynamically extended in the virtual machine state, otherwise it can only be expanded by adding another hard drive.

Default partitioning scheme for 2.CENTOS6.4-MINIMAL-64

That is: Hard disk size 16G, one boot partition, the rest is LVM partition, one VG, two LV (Lv_root and Lv_swap)

Process:

1. Turn off the virtual machine first.

2. Open the configuration item and resize the hard disk.

3. After booting

Fdisk-l See if the disk size is normal fdisk/dev/sdap,n,3,t,8e,p,wrebootpvcreate/dev/sda3pvdisplayvgdisplayvgextend volgroup/dev/ Sda3lvdisplaylvextend-l +4gb-n/dev/volgroup/lv_rootresize2fs/dev/volgroup/lv_rootreboot So the expansion is done.
