<title>Adjust the size of a filesystem</title>

  
A filesystem can be grown to make use of the free space after its

     partition. Often this is even possible while the filesystem is

     mounted.

  
To make space for another partition after the filesystem, it can be

     shrunk according to the free space within it.

  
Not all filesystems have resize support.

  
The partition size will be changed together with the filesystem size.

     It is also possible to resize a partition without a filesystem in the

     same way.

<steps>

  <title>Resize a filesystem/partition</title>

  <item>

    
Open <app>Disks</app> from the <gui>Activities</gui> overview.

  </item>

  <item>

    
Select the disk containing the filesystem in question from the list

       of storage devices on the left. If there is more than one volume on

       the disk, select the volume which contains the filesystem.

  </item>

  <item>

    
In the toolbar underneath the <gui>Volumes</gui> section, click the

       menu button. Then click <gui>Resize Filesystem…</gui> or

       <gui>Resize…</gui> if there is no filesystem.

  </item>

  <item>

    
A dialog will open where the new size can be chosen. The filesystem will

       be mounted to calculate the minimum size by the amount of current

       content. If shrinking is not supported the minimum size is the current

       size. Leave enough space within the filesystem when shrinking to ensure

       that it can work fast and reliably.

    
Depending on how much data has to be moved from the shrunk part, the

       filesystem resize may take longer time.

    <note style="warning">

      
The filesystem resize automatically involves

         <link xref="disk-repair">repairing</link> of the filesystem. Therefore

         it is advised to back up important data before starting. The action

         must not be stopped or it will result in a damaged filesystem.

    </note>

  </item>

  <item>

      
Confirm to start the action by clicking

         <gui style="button">Resize</gui>.

   
The action will unmount the filesystem if resizing a mounted filesystem

      is not supported. Be patient while the filesystem is resized.

  </item>

  <item>

    
After completion of the needed resize and repair actions the filesystem

       is ready to be used again.
