NAME         top

       lvm2-activation-generator  -  generator for systemd units to activate
       LVM volumes on boot

SYNOPSIS         top

       /usr/lib/systemd/system-generators/lvm2-activation-generator

DESCRIPTION         top

       The lvm2-activation-generator is called by systemd(1) on boot to
       generate systemd units at runtime to activate LVM Logical Volumes
       (LVs) when global/event_activation=0 is set in lvm.conf(5).  These
       units use vgchange -ay to activate LVs.

       If event_activation=1, the lvm2-activation-generator exits
       immediately without generating any systemd units, and LVM fully
       relies on event-based activation to activate LVs.  In this case,
       event-generated pvscan --cache -aay commands activate LVs.

       These systemd units are generated by lvm2-activation-generator:

       lvm2-activation-early.service is run before systemd's special
       cryptsetup.target to activate LVs that are not layered on top of
       encrypted devices.

       lvm2-activation.service is run after systemd's special
       cryptsetup.target to activate LVs that are layered on top of
       encrypted devices.

       lvm2-activation-net.service is run after systemd's special remote-
       fs-pre.target to activate LVs that are layered on attached remote
       devices.

       Note that all the underlying LVM devices (Physical Volumes) need to
       be present when the service is run. If the there are any devices that
       appear to the system later, LVs using these devices need to be
       activated directly by lvchange(8) or vgchange(8).

       The lvm2-activation-generator implements the Generators Specification
       as referenced in systemd(1).
