====== Logical Volume Manager (LVM) ======

===== Reducing Logical Volume =====
  - Unmount Logical Volume (LV) containing the filesystem which you want to resize.<code># umount /dev/lv/home</code>
  - Check the filesystem with e2fsck first.<code># e2fsck -f /dev/lv/home</code>
  - Resize the filesystem.<code># resize2fs /dev/lv/home 9G</code>
  - Resize LV.<code># lvresize -L10G /dev/lv/home</code>
  - Check the status of the LV.<code># lvdisplay /dev/q/home</code>
  - Check and resize filesystem to the maximum size of LV.<code># e2fsck -f /dev/lv/home
# resize2fs /dev/lv/home</code>

===== Growing Logical Volume =====
  - Unmount LV containing the filesystem which you want to resize.<code># umount /dev/lv/data</code>
  - Check the filesystem with e2fsck first.<code># e2fsck -f /dev/lv/data</code>
  - Check the remaining free physical extents.<code># vgdisplay</code>
  - Resize the LV.<code># lvresize -L +50,01G /dev/lv/data</code>
  - Check and resize filesystem to the maximum size of LV.<code># e2fsck -f /dev/lv/data
# resize2fs /dev/lv/data</code>
