擴展Fedora 16虛擬機的根分區磁盤容量（VMware workstation 7）
1. 關閉虛擬機fedora 16，通過vmware的虛擬機/設置/來擴展磁盤容量（8G）；
2. 通過命令parted -l /dev/sda print確認磁盤空間已正確增加；
3. 因為fedora 16使用GPT,所有不用fdisk而用parted來創建新加磁盤空間的分區(lvm)：
3.1 [root@fedora ~]# parted /dev/sda (輸入的命令)
GNU Parted 3.0
Using /dev/sda
Welcome to GNU Parted! Type 'help' to view a list of commands.
(parted) print (輸入的命令)
Model: VMware, VMware Virtual S (scsi)
Disk /dev/sda: 16.1GB （顯示磁盤整體空間）
Sector size (logical/physical): 512B/512B
Partition Table: gpt
Number Start End Size File system Name Flags
1 1049kB 2097kB 1049kB bios_grub
2 2097kB 526MB 524MB ext4 ext4 boot
3 526MB 8589MB 8063MB lvm
（已分區的卻只有8G，剛擴展的8G並未在此顯示）
3.2 (parted)mkpart newpart 8589MB 16.0G (將擴展的8G建立為新分區)
(parted) print
Model: VMware, VMware Virtual S (scsi)
Disk /dev/sda: 16.1GB
Sector size (logical/physical): 512B/512B
Partition Table: gpt
Number Start End Size File system Name Flags
1 1049kB 2097kB 1049kB bios_grub
2 2097kB 526MB 524MB ext4 ext4 boot
3 526MB 8589MB 8063MB lvm
4 8589MB 16.0GB 7411MB newpart
(parted) set 4 lvm (將新建分區設定為lvm)
New state? [on]/off? on
(parted) print
Model: VMware, VMware Virtual S (scsi)
Disk /dev/sda: 16.1GB
Sector size (logical/physical): 512B/512B

1 1049kB 2097kB 1049kB bios_grub

3 526MB 8589MB 8063MB lvm
4 8589MB 16.0GB 7411MB newpart lvm
4. 利用lvm管理工具將新建分區擴展到根分區：
4.1 [root@fedora ~]# vgdisplay (查看lvm卷組名稱)
--- Volume group ---
VG Name vg_fedora
……….
4.2 pvcreate /dev/sda4 (創建新物理卷)
4.3 vgextend vg_fedora /dev/sda4 (擴展到卷組)
4.4 lvdisplay
--- Logical volume ---
LV Name /dev/vg_fedora/lv_root
VG Name vg_fedora
………….
4.5 lvextend /dev/vg_fedora/lv_root /dev/sda4 (擴展到邏輯卷)
4.6 resize2fs /dev/vg_fedora/lv_root (刷新根分區邏輯卷的容量)
