linux 挂载云盘 NT只能挂载2T，使用parted挂载超过2T云盘

本文主要是介绍linux 挂载云盘 NT只能挂载2T，使用parted挂载超过2T云盘，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

一、删除原来挂载好的云盘和分区

1、查看挂载号的云盘

fdisk -l

发现我们有5千多G但是只挂载了2T，心里非常的慌张！十分的不爽！

好，我们把它干掉，重新分区！

2、解除挂载

umount /homeE

没保存跳转到（7），发现报错

3、查看被挂载的文件被调用情况

fuser -mv /homeE

没报错跳转到（5），发现报错

4、下载依赖

yum install -y psmisc

可能会有点慢，等几分钟。

安装完成！

5、再来查看被挂载的文件被调用情况

fuser -mv /homeE

强制删除调用进程！

kill -9 12828

查询到被调用的全部进程都要删掉！

6、再来解除挂载

umount /homeE

没有提示。

7、删除分区

fdisk /dev/vdd

[root@ecs-87a2-0202396 /]# fdisk /dev/vddWARNING: The size of this disk is 5.5 TB (5497558138880 bytes).
DOS partition table format can not be used on drives for volumes
larger than (2199023255040 bytes) for 512-byte sectors. Use parted(1) and GUID 
partition table format (GPT).Welcome to fdisk (util-linux 2.23.2).Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.# 查看分区情况

大功告成！

二、使用parted挂载（超过2T）云盘

1、查看我们的云盘地址

fdisk -l

可以看到我们云盘的地址是：/dev/vdd

2、挂载云盘

# 进入parted模式
[root@ecs-87a2-0202396 /]# parted /dev/vdd
