4.4.4. Changing the Parameters of a Logical Volume Group

To change the parameters of a logical volume, use the lvchange command. For a listing of the parameters you can change, see the lvchange(8) man page.
You can use the lvchange command to activate and deactivate logical volumes. To activate and deactivate all the logical volumes in a volume group at the same time, use the vgchange command, as described in Section 4.3.6, “Changing the Parameters of a Volume Group”.
The following command changes the permission on volume lvol1 in volume group vg00 to be read-only.
lvchange -pr vg00/lvol1
