在VMWARElinux虚拟机中扩展动态磁盘容量

1、在做之前，linux虚拟机的配置如下：

[root@jhrzftp~]#df-h

/dev/sda199M12M83M13%/boot

[root@jhrzftp~]#fdisk-l

2、启动虚拟机，打开虚拟机的settings，按照以下步骤新增加一块40GB的HardDisk（SCSI），最后重启linux虚拟机生效：

3、增加硬盘后，重启机器后，可以看到多了块硬盘/dev/sdb

[root@jhrzftp~]#fdisk-l

Disk/dev/sda:

115.9GB,115964116992bytes

255heads,63sectors/track,14098cylinders

Units=cylindersof16065*512=8225280bytes

Disk/dev/sdbdoesn'tcontainavalidpartitiontable

[root@jhrzftp~]#

4、将/dev/sdb添加到VolGroup00组里，并把LogVol00的容量扩展20GB，过程如下：

[root@jhrzftp~]#fdisk/dev/sdb

[root@jhrzftp~]#

（至此，可以看到VolGroup00-LogVol00的大小由原来的103G变为122G）

5、整个完成之后，linux虚拟机的配置如下：
