1）關掉Linux虛擬機，運行vmkfstools命令擴展vmdk文件。原大小為50G，現在擴展為65G。vmkfstools -X 65G CentOS53.vmdk
2）開啟Linux虛擬機，可以通過以下命令可以查看新增的可用空間。[root@CentOS53 ~]# parted
GNU Parted 1.8.1
Using /dev/sda
Welcome to GNU Parted! Type 'help' to view a list of commands.

3）運行disk /dev/sda后輸入P查看分區結果如下，并記錄下來(/dev/sda9加載在/data分區上)。可見總共有8485個cylinder，但最后一個分區只是到6527就結束了。這說明后面還有硬盤空間。Disk /dev/sda: 69.7 GB, 69793218560 bytes
255 heads, 63 sectors/track, 8485 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System
/dev/sda1 * 1 13 104391 83 Linux
/dev/sda2 14 535 4192965 83 Linux
/dev/sda3 536 796 2096482 82 Linux swap / Solaris
/dev/sda4 797 6527 46034257 5 Extended
/dev/sda5 797 1057 2096451 83 Linux
/dev/sda6 1058 1318 2096451 83 Linux
/dev/sda7 1319 1449 1052226 83 Linux
/dev/sda8 1450 1580 1052226 83 Linux
/dev/sda9 1581 6527 39736746 83 Linux
4）輸入d刪除擴展分區/dev/sda4，這樣所有的邏輯分區就從分區表中消失了（不要害怕，呵呵）。
5）輸入n創建新的擴展分區，并創建原來（/dev/sda9除外）所有的邏輯分區并保持原來的起始、結束cylinder地址不變。/dev/sda9的起始地址不變，結束地址改為8485。新的分區表如下。確認無誤后輸入w已保存生效。Command (m for help): p Disk /dev/sda: 69.7 GB, 69793218560 bytes
255 heads, 63 sectors/track, 8485 cylinders

/dev/sda1 * 1 13 104391 83 Linux

/dev/sda7 1319 1449 1052226 83 Linux
/dev/sda8 1450 1580 1052226 83 Linux
/dev/sda9 1581 8485 55464381 83 Linux

6）查看改動后的分區大小。到目前為止，/data分區大小仍未改變。[root@CentOS53 ~]# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/sda8 996M 235M 710M 25% /
/dev/sda9 37G 177M 35G 1% /data
/dev/sda7 996M 34M 911M 4% /home
/dev/sda6 2.0G 76M 1.8G 5% /var
/dev/sda2 3.9G 1.4G 2.4G 38% /usr
/dev/sda5 2.0G 36M 1.9G 2% /usr/local
/dev/sda1 99M 17M 78M 18% /boot
tmpfs 506M 0 506M 0% /dev/shm

7）運行resize2fs /dev/sda9已擴展/data分區。（在2.6.X內核里無需先umount）[root@CentOS53 ~]# resize2fs /dev/sda9
resize2fs 1.39 (29-May-2006)
Filesystem at /dev/sda9 is mounted on /apps; on-line resizing required
