+<title>Repair a damaged filesystem</title>
+
+  <p>Filesystems can be corrupted due to unexpected power loss, system crashes
+     and unsafe removal of the drive.
+     After such an incident it is recommended to <em>repair</em> or at least
+     <em>check</em> the filesystem to prevent future data loss.</p>
+  <p>Sometimes a repair is required in order to mount or modify a filesystem.
+     Even if a <em>check</em> does not report any damage the filesystem might
+     still be marked as 'dirty' internally and require a repair.</p>
+
+<steps>
+  <title>Check if a filesystem is damaged</title>
+  <item>
+    <p>Open <app>Disks</app> from the <gui>Activities</gui> overview.</p>
+  </item>
+  <item>
+    <p>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.</p>
+  </item>
+  <item>
+    <p>In the toolbar underneath the <gui>Volumes</gui> section, click the
+    menu button. Then click <gui>Check Filesystem…</gui>.</p>
+  </item>
+  <item>
+    <p>Depending on how much data is stored in the filesystem a check may take
+       longer time. Confirm to start the action in the dialog that pops up.</p>
+   <p>The action will not modify the filesystem but will unmount it if needed.
+      Be patient while the filesystem is checked.</p>
+  </item>
+  <item>
+    <p>After completion you will be notified whether the filesystem is damaged.
+       Note that in some cases even if the filesystem is undamaged it still
+       may need to be repaired to reset an internal 'dirty' marker.</p>
+  </item>
+</steps>
+
+<note style="warning">
+ <title>Possible data loss when repairing</title>
+  <p>If the filesystem structure is damaged it can affect the files stored
+     in it. In some cases these files can not be brought into a valid form
+     again and will be deleted or moved to a special directory. It is normally
+     the <em>lost+found</em> folder in the top level directoy of the filesystem
+     where these recovered file parts can be found.</p>
+  <p>If the data is too valuable to be lost during this process, you are
+     advised to back it up by saving an image of the volume before
+     repairing.</p>
+  <p>This image can be then processed with forensic analysis tools like
+     <app>sleuthkit</app> to further recover missing files and data parts
+     which were not restored during the repair, and also previously removed
+     files.</p>

+  <item>
+    <p>After completion you will be notified whether the filesystem could be

+    <p>If the filesystem could not be repaired, back it up by saving an image
+       of the volume to be able to retrieve important files later. This can
+       be done by mounting the image read-only or using forensic analysis tools
+       like <app>sleuthkit</app>.</p>

+<title>Adjust the size of a filesystem</title>
+
+  <p>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.</p>
+  <p>To make space for another partition after the filesystem, it can be
+     shrunk according to the free space within it.</p>
+  <p>Not all filesystems have resize support.</p>
+  <p>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.</p>
+
+<steps>
+  <title>Resize a filesystem/partition</title>
+  <item>
+    <p>Open <app>Disks</app> from the <gui>Activities</gui> overview.</p>
+  </item>
+  <item>
+    <p>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.</p>
+  </item>
+  <item>
+    <p>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.</p>
+  </item>
+  <item>
+    <p>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.</p>
+    <p>Depending on how much data has to be moved from the shrunk part, the
+       filesystem resize may take longer time.</p>
+    <note style="warning">
+      <p>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.</p>
+    </note>
+  </item>
+  <item>
+      <p>Confirm to start the action by clicking
+         <gui style="button">Resize</gui>.</p>
+   <p>The action will unmount the filesystem if resizing a mounted filesystem
+      is not supported. Be patient while the filesystem is resized.</p>
+  </item>
+  <item>
+    <p>After completion of the needed resize and repair actions the filesystem
+       is ready to be used again.</p>
