我在EC2实例上安装了cPanel和WHm。
EC2 EBS容量为100GB
CentOS 6 x86_64（2014_09_29）EBS pv-1-adc4348e-1dc3-41df-b833-e86ba57a33d6-ami-809020e8.2（ami-bc8131d4）
这是df -h显示的内容：
Filesystem Size Used Avail Use% Mounted on
/dev/xvde1 7.8G 6.6G 834M 89% /
tmpfs 3.7G 0 3.7G 0% /dev/shm
/usr/tmpDSK 485M 11M 449M 3% /tmp
EBS安装在
/dev/sda我正在尝试增加
xvde1的大小以几乎填满100GB当我运行
resize2fs /dev/xvde1我得到这个：root@vs1 [~]# resize2fs /dev/xvde1
resize2fs 1.41.12 (17-May-2010)
The filesystem is already 2096896 blocks long. Nothing to do!
我已经尝试过此处所述的解决方案：EC2 Can't resize volume after increasing size
但是当我重新启动实例时，它卡在
1/2 Status Checks上我看到一些说明可以在
16上启动分区，也可以使用与原始配置中相同的启动。这没有用。这是一些我尝试过的其他信息：

这是耗时18个小时的完整构建的最后一步。
我可能只是精神错乱。任何和所有帮助将不胜感激！

最佳答案
要扩展JD的答案，请按照以下步骤操作：df -h＃打印启动分区的名称lsblk＃在所有块设备上显示信息
您将从输出中看到根分区的磁盘名称。例如，您可能会看到以下内容：xvde 202:64 0 32G 0 disk└─xvde1 202:65 0 8G 0 part /
我们的目标是使xvde1使用xvde中的全部可用空间。
调整分区大小的方法如下：fdisk /dev/xvda（磁盘名称，而不是您的分区）
这进入fdisk实用程序。u＃将显示更改为扇区p＃打印信息d＃删除分区n＃新分区p＃主分区1＃分区号2048＃第一部门
按Enter接受默认值p＃打印信息a＃切换可启动标志1＃选择分区1w＃将表写入磁盘并退出
现在，重新启动实例：reboot
回来后，请执行以下操作：resize2fs /dev/xvde1（您分区的名称，而不是块设备）
最后验证新磁盘的大小：df -h
