An active LV can be used through a block device, allowing data on the LV to be accessed. y<\/b> makes LVs active, or available. n<\/b> makes LVs inactive, or unavailable. The block device for the LV is added or removed from the system using device-mapper in the kernel. A symbolic link \/dev\/VGName\/LVName pointing to the device node is also added\/removed. All software and scripts should access the device through the symbolic link and present this as the name of the device. The location and name of the underlying device node may depend on the distribution, configuration (e.g. udev), or release version. ay<\/b> specifies autoactivation, in which case an LV is activated only if it matches an item in lvm.conf activation\/auto_activation_volume_list. If the list is not set, all LVs are considered to match, and if if the list is set but empty, no LVs match. Autoactivation should be used during system boot to make it possible to select which LVs should be automatically activated by the system.

(This does not include the “mirror” type, see “raid1” instead.) partial<\/b> allows any LV with missing PVs to be activated, and should only be used for recovery or repair.

Each VG and LV has an allocation policy which can be changed with vgchange\/lvchange, or overriden on the command line. normal<\/b> applies common sense rules such as not placing parallel stripes on the same PV. inherit<\/b> applies the VG policy to an LV. contiguous<\/b> requires new PEs be placed adjacent to existing PEs. cling<\/b> places new PEs on the same PV as existing PEs in the same stripe of the LV. If there are sufficient PEs for an allocation, but normal does not use them, anywhere<\/b> will use them even if it reduces performance, e.g. by placing two stripes on the same PV. Optional positional PV args on the command line can also be used to limit which PVs the command will use for allocation.
