{{Admon/note|Using LVM in Fedora's Rescue Mode|The Fedora installation DVD has a "rescue mode" which may be used to fix problems on a previously-installed system -- useful if (for example) you have deleted or messed up a file that is necessary to successfully boot the system. In rescue mode, only a single LVM command is available: <code>lvm</code>. To use any of the lvm commands, you can type <code>lvm</code> followed by the name of the command you wish to execute. Alternately, typing <code>lvm</code> by itself will start the LVM shell, and you can then type any of the lvm commands directly. To use non-LVM commands, exit from the LVM shell.}}
