==Introduction== 

In this article you will see how to extend a partition hot on Linux with fdisk. <br>

==Context==

In our case, we will have a partition mounted on /var, named /dev/xvdb1 who does 10GB <br>
We would like to extend this partition to the maximum (xvdb made 20GB) <br>

==Place== 
===Disassembly of the partition===
In order to make any changes on a partition, he must take it apart. <br>
The command to unmount our partition is: <syntaxhighlight lang="bash"> umount /dev/xvdb1 </syntaxhighlight> <br>

An error of the type: <br>
[[File: Umonterror.PNG]] <br>

Please close the process on this score as well as open files with their programs or related it users: <br>
Process: <syntaxhighlight lang="bash"> fuser -kmiuv /dev/xvdb1 </syntaxhighlight> <br>
Open files: <syntaxhighlight lang="bash"> lsof | grep /var </syntaxhighlight> <br>

===Partitioning===
Type the command: <syntaxhighlight lang="bash"> fdisk </syntaxhighlight> <br>
Choose the disk on which is the partition to extend: <syntaxhighlight lang="bash"> fdisk /dev/xvdb </syntaxhighlight> <br>

<span style="font-size: 150%; color:red ">/!\ Étape très importante /!\</span> <br>
<span style="color:red"> Tapez </span>
<syntaxhighlight lang="bash"> p </syntaxhighlight>
<span style="color:red;"> Afin de noter le cylindre de début de la partition, ici 2048. </span> <br>

<br>

Enter this option to delete the partition in the partition table, this does not erase the data on the disc: 
 <syntaxhighlight lang="bash"> d </syntaxhighlight> 
Then enter the number of the partition to delete. <br>
<br>

Then enter this option to create a new partition: <br>
<syntaxhighlight lang="bash"> n </syntaxhighlight>
Enter the number that you noted above for the First sector and the default number for the Last sector (If you want to extend it to the maximum) <br>
[[File: Sector.PNG]] <br>
<br>

If everything went well spent so far, we will save the new table of partitions with this option: <br>
<syntaxhighlight lang="bash"> w </syntaxhighlight> 
<br>

Restart: <br>
<syntaxhighlight lang="bash"> reboot </syntaxhighlight>
<br>

It remains more to extend the filesystem with the command: <br>
<syntaxhighlight lang="bash"> resize2fs /dev/xvdb1 </syntaxhighlight>
