扩展VirtualBox虚拟机磁盘容量(2)

p> 

p>[python] 

p>[root@localhost ~]# lvresize -l +100%FREE /dev/mapper/vg_wsgzg-lv_root  

p> Extending logical volume lv_root to 17.53 GiB  

p> Logical volume lv_root successfully resized  

p>e．  执行resize2fs/dev/mapper/vg_wsgzg-lv_root重新设置文件系统

p> 

p>[python] 

p>[root@localhost ~]# resize2fs /dev/mapper/vg_wsgzg-lv_root  

p>   resize2fs1.41.12 (17-May-2010)  

p>   Filesystemat /dev/mapper/vg_wsgzg-lv_root is mounted on /; on-line resizing required  

p>   olddesc_blocks = 1, new_desc_blocks = 2  

p>   Performingan on-line resize of /dev/mapper/vg_wsgzg-lv_root to 4595712 (4k) blocks.  

p>   Thefilesystem on /dev/mapper/vg_wsgzg-lv_root is now 4595712 blocks long.  

p>f．  执行df -h -T验证扩展磁盘容量

p> 

p>[python] 

p>[root@localhost ~]# df -h -T  

p>   文件系统    类型      容量  已用  可用 已用%% 挂载点  

p>   /dev/mapper/vg_wsgzg-lv_root  

p>              ext4     18G  13G  4.8G  73% /  

p>6.      重启CentOS，磁盘容量扩展成功
