1）关掉Linux虚拟机，运行vmkfstools命令扩展vmdk文件。原大小为50G，现在扩展为65G。vmkfstools -X 65G CentOS53.vmdk
2）开启Linux虚拟机，可以通过以下命令可以查看新增的可用空间。[root@CentOS53 ~]# parted
GNU Parted 1.8.1
Using /dev/sda
Welcome to GNU Parted! Type 'help' to view a list of commands.

3）运行disk /dev/sda后输入P查看分区结果如下，并记录下来(/dev/sda9加载在/data分区上)。可见总共有8485个cylinder，但最后一个分区只是到6527就结束了。这说明后面还有硬盘空间。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）输入d删除扩展分区/dev/sda4，这样所有的逻辑分区就从分区表中消失了（不要害怕，呵呵）。
5）输入n创建新的扩展分区，并创建原来（/dev/sda9除外）所有的逻辑分区并保持原来的起始、结束cylinder地址不变。/dev/sda9的起始地址不变，结束地址改为8485。新的分区表如下。确认无误后输入w已保存生效。Command (m for help): p Disk /dev/sda: 69.7 GB, 69793218560 bytes

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

6）查看改动后的分区大小。到目前为止，/data分区大小仍未改变。[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）运行resize2fs /dev/sda9已扩展/data分区。（在2.6.X内核里无需先umount）[root@CentOS53 ~]# resize2fs /dev/sda9
resize2fs 1.39 (29-May-2006)
Filesystem at /dev/sda9 is mounted on /apps; on-line resizing required
