弹性云升级C盘大小后,系统不会自动扩容C盘大小,需按照一下操作完成扩容,扩容前,请关闭服务器虚拟内存和mysql及mssql服务,避免因扩容造成数据损坏


Win2008系统或者Win2012手工操作扩容:

首先请检查您要扩展到的分区是否有设置虚拟内存,如果有请先取消虚拟内存,并重启。

重启后点击开始--运行,输入cmd,进入命令窗口,如图:

依次输入以下命令:

diskpart              回车
list  volume         回车(显示卷,找到C盘卷号,如:卷1)
select volume 1   回车(1在这里表示C盘卷标)
extend                回车(表示将余下的空间全部增加到C盘)

操作流程如图(红色方框中是输入的命令):

Win2003系统使用下列方法扩容C盘:

1.下载分区调整.rar 

下载报错到D盘(必须),然后解压到D盘

2.双击launcher.exe 运行分区调整

3.接下来,将C盘大小调整,如下图

点击是,然后点击

等待执行完成,即可完成C盘扩容

红色为您要键入的指令,绿色为需要注意的内容,蓝色为说明


特别提醒:删除分区后一定要先建立分区再保存,删除后点了保存会导致数据丢失,如果对linux不熟悉的,建议提交维护工单我司手工处理,费用30元。该操作有风险,为避免误操作导致数据丢失,操作前请对您的重要数据进行备份!

Command (? for help): w


Final checks complete. About to write GPT data. THIS WILL OVERWRITE EXISTING

PARTITIONS!!


Do you want to proceed? (Y/N): y

OK; writing new GUID partition table (GPT) to /dev/vda.

Warning: The kernel is still using the old partition table.

The new table will be used at the next reboot.

The operation has completed successfully.


[root@ebs ~]#reboot                        //重启让分区生效

[root@ebs ~]#resize2fs -f /dev/vda1                 //开始扩容根分区

resize2fs -f /dev/vda1

resize2fs 1.41.12 (17-May-2010)

Filesystem at /dev/vda1 is mounted on /; on-line resizing required

old desc_blocks = 2, new_desc_blocks = 4

Performing an on-line resize of /dev/vda1 to 13106939 (4k) blocks.

The filesystem on /dev/vda1 is now 13106939 blocks long.


[root@ebs ~]#df -vh                            //完成,查看新的根分区大小
