Often this is even possible while the filesystem is 23 mounted.</p> 24 <p>To make space for another partition after the filesystem, it can be 25 shrunk according to the free space within it.</p> 26 <p>Not all filesystems have resize support.</p> 27 <p>The partition size will be changed together with the filesystem size. 28 It is also possible to resize a partition without a filesystem in the 29 same way.</p> 30 31<steps> 32 <title>Resize a filesystem/partition</title> 33 <item> 34 <p>Open <app>Disks</app> from the <gui>Activities</gui> overview.</p> 35 </item> 36 <item> 37 <p>Select the disk containing the filesystem in question from the list 38 of storage devices on the left. If there is more than one volume on 39 the disk, select the volume which contains the filesystem.</p> 40 </item> 41 <item> 42 <p>In the toolbar underneath the <gui>Volumes</gui> section, click the 43 menu button. Then click <gui>Resize Filesystem…</gui> or 44 <gui>Resize…</gui> if there is no filesystem.</p> 45 </item> 46 <item> 47 <p>A dialog will open where the new size can be chosen. The filesystem will 48 be mounted to calculate the minimum size by the amount of current 49 content. If shrinking is not supported the minimum size is the current 50 size. Leave enough space within the filesystem when shrinking to ensure 51 that it can work fast and reliably.</p> 52 <p>Depending on how much data has to be moved from the shrunk part, the 53 filesystem resize may take longer time.</p> 54 <note style="warning"> 55 <p>The filesystem resize automatically involves 56 <link xref="disk-repair">repairing</link> of the filesystem. Therefore 57 it is advised to back up important data before starting. The action 58 must not be stopped or it will result in a damaged filesystem.</p> 59 </note> 60 </item> 61 <item> 62 <p>Confirm to start the action by clicking 63 <gui style="button">Resize</gui>.</p> 64 <p>The action will unmount the filesystem if resizing a mounted filesystem 65 is not supported. Be patient while the filesystem is resized.</p> 66 </item> 67 <item> 68 <p>After completion of the needed resize and repair actions the filesystem 69 is ready to be used again.</p> 70 </item> 71</steps> 72 73</page> 74
