本文介绍了附加在sda的EC2存储为/ dev / xvde1无法调整大小的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我有cPanel&



EC2 EBS卷为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：

 文件系统大小使用可用性％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



我试图增加 xvde1 几乎填满100GB



当我运行 resize2fs / dev / xvde1 / p> 

  root @ vs1 [〜]＃resize2fs / dev / xvde1 
 resize2fs 1.41.12（2010年5月17日） 
文件系统已经是2096896块长。没事做！

我试过这里说的解决方案： EC2在增加大小后无法调整卷大小



重新启动它遇到的实例 1/2状态检查



我看到一些声明要启动分区 16 ，并使用与原始配置中相同的开头。这不行。



这里是我尝试过的一些更多的信息和其他事情：

  root @ vs1 [〜]＃resize2fs / dev / xvde1 
 resize2fs 1.41.12（2010年5月17日）
文件系统已经是2096896块长。没事做！

这是完成构建的最后一步，已经用了18个小时。 / p>

我可能只是妄想。

 Tpmfront：Info关闭tpmfront


解决方案

p>要扩展JD的答案，这里就是做什么：



df -h #print您的引导分区



lsblk #s显示所有块设备的信息



您将从该输出看到您的根分区的磁盘名称。例如，你可能看到这样的：

xvde 202：64 0 32G 0磁盘
└─xvde1202：65 0 8G 0部分/



我们的目标是让 xvde1 c $ c> xvde 。
以下是调整分区大小的方法：



fdisk / dev / xvda 您的分区）
这进入 fdisk 实用程序。


  1. code> u ＃将显示更改为部门

  2. p ＃打印信息

  3. d ＃删除分区

  4. n #New partition


  6. p #Primary partition
    7. #Partition number
  7. 2048 ＃第一部门


  9. 输入以接受默认值
    10. a #Toggle the bootable flag
  10. 1 #Select partition 1

  11. w ＃将表格写入磁碟并退出

您的实例：
重新启动



返回后：



resize2fs / dev / xvde1 （分区的名称，而不是块设备）



最后验证新磁盘大小：
df -h


I have cPanel & WHm installed on an EC2 instance.

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)

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

The EBS is mounted at /dev/sda

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

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!

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

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

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.

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

root@vs1 [~]# resize2fs /dev/xvde1

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

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

The system log on the server shows this, not sure if it is any help:

============= Init TPM Front ================
Tpmfront:Error Unable to read device/vtpm/0/backend-id during tpmfront initialization! error = ENOENT
Tpmfront:Info Shutting down tpmfront

解决方案

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

df -h #print the name of your boot partition

lsblk #show info on all your block devices

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 /

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

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

  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

Now, reboot your instance: reboot

After it comes back do:

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

And finally verify the new disk size: df -h

这篇关于附加在sda的EC2存储为/ dev / xvde1无法调整大小的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
