Preventing Automatic Activation of Volume Groups

It is important to prevent package volume groups from being activated at system boot time by the /etc/lvmrc file. To ensure that this does not happen, edit the /etc/lvmrc file on all nodes. Set AUTO_VG_ACTIVATE to 0, then include all the volume groups that are not cluster bound in the custom_vg_activation function. Volume groups that will be used by packages should not be included anywhere in the file, since they will be activated and deactivated by control scripts.

	NOTE: The root volume group does not need to be included in the custom_vg_activation function, since it is automatically activated before the /etc/lvmrc file is used at boot time.
