0001 <sect1 id="howto-resizepartition"> 0002 <title>How-To: Resizing a Partition</title> 0003 0004 <para> 0005 This how-to explains the resizing of a <glossterm linkend="glossary-partition">partition</glossterm> that is becoming too full. See the following screenshot for the initial situation before resizing: 0006 </para> 0007 0008 <para> 0009 <screenshot> 0010 <mediaobject> 0011 <imageobject><imagedata fileref="resize_howto_1.png" format="PNG"/></imageobject> 0012 <textobject><phrase>Main window before resizing partitions</phrase></textobject> 0013 </mediaobject> 0014 </screenshot> 0015 </para> 0016 0017 <para> 0018 On <glossterm linkend="glossary-device">device</glossterm> <quote>/dev/sdb</quote>, partition <quote>sdb2</quote> has only little free space left while the other partition, <quote>sdb1</quote>, is far from being full. For that reason it seems advisable to make the first partition a little smaller and grow <quote>sdb2</quote> so it has more free space available. 0019 </para> 0020 0021 <note> 0022 <title>Note: You cannot modify mounted partitions.</title> 0023 <para>In the screenshot above both partitions are not currently mounted. If one or both of them were mounted you would have to unmount them first using <xref linkend="menu-partition-mount"/>.</para> 0024 </note> 0025 0026 <para> 0027 The first step is to make more room for the partition to grow, so start by shrinking <quote>sdb1</quote>. Click on the partition and choose <xref linkend="menu-partition-resize"/>. The following dialog comes up: 0028 </para> 0029 0030 <para> 0031 <screenshot> 0032 <mediaobject> 0033 <imageobject><imagedata fileref="resize_howto_2.png" format="PNG"/></imageobject> 0034 <textobject><phrase>Resize dialog before resizing /dev/sdb1</phrase></textobject> 0035 </mediaobject> 0036 </screenshot> 0037 </para> 0038 0039 <para> 0040 The dialog allows you to resize the partition in multiple ways. You can either drag the right handle to the left until the partition has the desired size or simply enter the size in the <guilabel>Size</guilabel> text field. Another possibility would be to adjust the size by clicking on the little arrows next to the text field, but that is a little tedious for larger changes. 0041 </para> 0042 0043 <para> 0044 Whichever way you prefer for setting the new size, the dialog should now look like this: 0045 </para> 0046 0047 <para> 0048 <screenshot> 0049 <mediaobject> 0050 <imageobject><imagedata fileref="resize_howto_3.png" format="PNG"/></imageobject> 0051 <textobject><phrase>Resize dialog after resizing /dev/sdb1</phrase></textobject> 0052 </mediaobject> 0053 </screenshot> 0054 </para> 0055 0056 <para> 0057 After you click on <guibutton>OK</guibutton>, a new operation is added to the pending operations list and the graphical view and tree view of the device are updated to reflect the new situation: 0058 </para> 0059 0060 <para> 0061 <screenshot> 0062 <mediaobject> 0063 <imageobject><imagedata fileref="resize_howto_4.png" format="PNG"/></imageobject> 0064 <textobject><phrase>Main window after resizing /dev/sdb1</phrase></textobject> 0065 </mediaobject> 0066 </screenshot> 0067 </para> 0068 0069 <note> 0070 <title>Note: Operations are previewed first before applying them.</title> 0071 <para>Although the main window reflects the device's state how it will be after applying the new operation, the operation has in fact not been applied yet: While operations are pending you can still undo them (one by one using <xref linkend="menu-edit-undo"/> or <xref linkend="menu-edit-clear"/> to undo all of them) or quit &partman;, and nothing will have been modified at all.</para> 0072 </note> 0073 0074 <para> 0075 Now that there is some free space between the two partitions you can move and grow partition <quote>sdb2</quote>. First, click on <quote>sdb2</quote> and choose <xref linkend="menu-partition-resize"/> again. The resize dialog comes up once more, this time for the second partition. Drag its left handle to the leftmost end so that the dialog looks like this: 0076 </para> 0077 0078 <para> 0079 <screenshot> 0080 <mediaobject> 0081 <imageobject><imagedata fileref="resize_howto_5.png" format="PNG"/></imageobject> 0082 <textobject><phrase>Resize dialog after resizing /dev/sdb2</phrase></textobject> 0083 </mediaobject> 0084 </screenshot> 0085 </para> 0086 0087 <para> 0088 Be careful to make sure that the <guilabel>Free space before</guilabel> text field really does show <quote>0 MiB</quote> because otherwise there will be a little free space left between the partitions that will then be wasted. 0089 </para> 0090 0091 <para> 0092 Now click <guibutton>OK</guibutton> again. In the main window things now look like this: 0093 </para> 0094 0095 <para> 0096 <screenshot> 0097 <mediaobject> 0098 <imageobject><imagedata fileref="resize_howto_6.png" format="PNG"/></imageobject> 0099 <textobject><phrase>Main window after resizing /dev/sdb2</phrase></textobject> 0100 </mediaobject> 0101 </screenshot> 0102 </para> 0103 0104 <para> 0105 This already looks like what you wanted, so choose <xref linkend="menu-edit-apply"/>. A dialog box will come up and ask you if you are sure to apply the pending operations. Confirm this dialog box and &partman; will begin executing operations: 0106 </para> 0107 0108 <para> 0109 <screenshot> 0110 <mediaobject> 0111 <imageobject><imagedata fileref="resize_howto_7.png" format="PNG"/></imageobject> 0112 <textobject><phrase>&partman; is applying operations</phrase></textobject> 0113 </mediaobject> 0114 </screenshot> 0115 </para> 0116 0117 <para> 0118 While operations are being executed you can click on the plus-sign next to each operation in the list to find out the jobs it is made up of and see which job is currently being run. 0119 </para> 0120 0121 <para> 0122 Resizing a partition in the way you resized <quote>/dev/sdb2</quote> above always means it has to be moved to the left first before it can be grown because partitions can never be grown to the left directly. Unfortunately, moving such a large partition will take quite some time. It is not unusual for an operation like this to take several minutes or even more. 0123 </para> 0124 0125 <para> 0126 Finally, all operations will have been successfully completed: 0127 </para> 0128 0129 <para> 0130 <screenshot> 0131 <mediaobject> 0132 <imageobject><imagedata fileref="resize_howto_8.png" format="PNG"/></imageobject> 0133 <textobject><phrase>Progress dialog after successfully applying operations</phrase></textobject> 0134 </mediaobject> 0135 </screenshot> 0136 </para> 0137 0138 <para> 0139 By clicking on <guibutton>OK</guibutton> you can now close the progress dialog and return to the main window. &partman; will rescan your devices at this point so that might take a few seconds. 0140 </para> 0141 0142 <para> 0143 If you are interested in some more details about the operations that were just run click on <guibutton>Details</guibutton>. You will see the detailed report that is always generated (and updated on the fly) while &partman; executes operations: 0144 </para> 0145 0146 <para> 0147 <screenshot> 0148 <mediaobject> 0149 <imageobject><imagedata fileref="resize_howto_9.png" format="PNG"/></imageobject> 0150 <textobject><phrase>Progress dialog details</phrase></textobject> 0151 </mediaobject> 0152 </screenshot> 0153 </para> 0154 0155 <para> 0156 This report is particularly of interest if an error occurs while executing operations. A report shows each operation, each job and each external command that is being run and is thus very helpful when trying to track down problems. 0157 </para> 0158 0159 <para> 0160 You can save the report as <acronym>HTML</acronym> or view it in an external web browser. 0161 </para> 0162 0163 <tip> 0164 <para> 0165 Always save the detailed report as <acronym>HTML</acronym> when executing the operations fails with errors or warnings for later reference. You might also want to include it in a bug report you submit to the &kde; bug tracking system at <ulink url="https://bugs.kde.org">bugs.kde.org</ulink>. 0166 </para> 0167 </tip> 0168 0169 <para> 0170 To hide the details again click on <guibutton>Details</guibutton> and to finally close the progress dialog click on <guibutton>OK</guibutton>. 0171 </para> 0172 </sect1>
