在vmware中对linux扩展磁盘

1、Vm虚拟机下Linux扩展原有磁盘空间，详细步骤以下：

需注意如下几点： linux只能扩展磁盘容量而不能减少， 所填写的容量为总容量，即包含已分区的磁盘， 扩展容量时不能有快照哟，你们能够先把快照删除掉。

2.启动Linux，查看系统分区，并建立分区sda3，命令以下：红色字体命令，#后为注释：

[root@localhost~]#fdisk -l
Disk /dev/sda:32.2GB,32212254720 bytes

255heads,63sectors/track,3916cylinders
Units=cylindersof16065*512=8225280 bytes

DeviceBoot      Start      End        Blocks             Id       System

/dev/sda1  *        1            13         104391          83      Linux
/dev/sda2           14           1566    12474472+   8e      Linux LVM

#个人电脑有2个分区-sda1 sda2

[root@localhost~]#fdisk /dev/sda
