问题描述

我有 cPanel &WHm 安装在 EC2 实例上.

I have cPanel & WHm installed on an EC2 instance.

EC2 EBS 卷为 100GBCentOS 6 x86_64 (2014_09_29) EBS pv-1-adc4348e-1dc3-41df-b833-e86ba57a33d6-ami-809020e8.2 (ami-bc8131d4)

The EC2 EBS volume is 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:

This is what df -h shows:

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

I am trying to increase the size of the xvde1 to almost fill the 100GB

当我运行 resize2fs/dev/xvde1 我得到这个:

When I run resize2fs /dev/xvde1 i get this:

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增大尺寸

I have tried the solution stated here: EC2 Can't resize volume after increasing size

但是当我重新启动实例时，它会卡在 1/2 状态检查

But when i reboot the instance it gets stuck on 1/2 Status Checks

我看到了一些说明要在 16 上启动分区并使用与原始配置中相同的启动方式.这不起作用.

I saw something that stated to start the partition on 16 and also to use the same start as it is in the original configuration. This did not work.

这是我尝试过的更多信息和其他内容:

Here is some more information and other things that i have tried:

这是完整构建的最后一步，耗时超过 18 小时.

This is the last step in a complete build that has taken over 18 hours.

我可能只是精神错乱.任何和所有的帮助将不胜感激！

I may just be delirious. Any and all help will be greatly appreciated!

推荐答案

此答案很危险，自 2016 年以来尚未经过验证，如果您不知道发生了什么，则可能会删除您的分区.谨慎使用，也请参考下面@Dmitry 的回答.

This answer is dangerous, hasn't been verified since 2016, and has the potential to delete your partition if you're not aware of what's happening. Use with caution, and please reference @Dmitry's answer below as well.

为了扩展 JD 的答案，这正是要做的事情:

To expand on JD's answer, here's exactly what to do:

df -h #打印你的启动分区的名字

df -h #print the name of your boot partition

lsblk #显示所有块设备上的信息

lsblk #show info on all your block devices

您将从该输出中看到您的根分区的磁盘名称.例如，您可能会看到如下内容:

You'll see from that output what the name of the disk is of your root partition. For example, you probably see something like this:

xvde                               202:64   0   32G  0 disk 
└─xvde1                            202:65   0   8G  0 part /

我们的目标是让 xvde1 使用 xvde 的全部可用空间.以下是调整分区大小的方法:

Our goal is to make xvde1 use the whole available space from xvde. Here's how to resize your partition:

fdisk/dev/xvda(磁盘名，不是你的分区)这将进入 fdisk 实用程序.

fdisk /dev/xvda (the disk name, not your partition) This enters into the fdisk utility.

  1. u #将显示改为扇区
  2. p #打印信息
  3. d #删除分区
  4. n #新建分区
  5. p #主分区
  6. 1 #分区号
  7. 2048 #第一扇区
  8. 按 Enter 接受默认值
  9. p #打印信息
  10. a #切换可启动标志
  11. 1 #选择分区1
  12. w #将表写入磁盘并退出
  1. u #Change the display to sectors
  2. p #Print info
  3. d #Delete the partition
  4. n #New partition
  5. p #Primary partition
  6. 1 #Partition number
  7. 2048 #First sector
  8. Press Enter to accept the default
  9. p #Print info
  10. a #Toggle the bootable flag
  11. 1 #Select partition 1
  12. w #Write table to disk and exit

现在，重新启动您的实例:重启

Now, reboot your instance: reboot

回来后做:

resize2fs/dev/xvde1(你的分区名称，不是块设备)

resize2fs /dev/xvde1 (the name of your partition, not the block device)

最后验证新的磁盘大小:df -h

And finally verify the new disk size: df -h
