XenServer安装虚拟机---先扩容存放ISO镜像文件

我们都知道xenserver安装后，不管你的盘有多大，只有4G的空间。

故操作是：新建LV卷，可自定义大小

1、vgdisplay #先查看剩余空间

[root@XenServer /]# vgdisplay

2、lvdisplay VG_XenStorage-205eecff-2466-84fe-56d5-81472e44f3c2 #查看该区

[root@XenServer /]#  lvdisplay VG_XenStorage-205eecff-2466-84fe-56d5-81472e44f3c2

3、lvcreate -L 20GB -n iso VG_XenStorage-205eecff-2466-84fe-56d5-81472e44f3c2 #新建20G的lv卷iso

[root@XenServer /]#  lvcreate -L 20GB -n iso VG_XenStorage-205eecff-2466-84fe-56d5-81472e44f3c2



Logical volume "lviso" created

 

顺带提一下如何添加空间：

[root@XenServer /]#  lvcreate -n lviso -L +6G VG_XenStorage-205eecff-2466-84fe-56d5-81472e44f3c2



Logical volume "lviso" created

 

4、lvdisplay VG_XenStorage-205eecff-2466-84fe-56d5-81472e44f3c2 #再次查看该区

[root@XenServer /]#  lvdisplay VG_XenStorage-205eecff-2466-84fe-56d5-81472e44f3c2

5、mkfs.ext3 /dev/VG_XenStorage-205eecff-2466-84fe-56d5-81472e44f3c2/iso #格式化为ext3格式

[root@XenServer /]#  mkfs.ext3 /dev/VG_XenStorage-205eecff-2466-84fe-56d5-81472e44f3c2/iso

[root@XenServer /]#

6、mkdir /iso #在根目录下建立iso文件夹，用于ISO镜像文件的挂载

[root@XenServer /]#  mkdir /iso

[root@XenServer /]#

 

7、vgchange -a y #激活所有卷组

8、mount /dev/VG_XenStorage-205eecff-2466-84fe-56d5-81472e44f3c2/lviso /iso #挂载/ISO文件夹下的iso镜像文件

[root@XenServer /]#  mount /dev/VG_XenStorage-205eecff-2466-84fe-56d5-81472e44f3c2/lviso  /iso

[root@XenServer /]#

 

9、df -h #查看容量

[root@XenServer /]#  df -h

10、通过Xftp 软件将 下载好的iso镜像文件上传到 /iso 目录中 注意更改 文件权限755

在这就可以转到XenCenter客户端操作了
