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

SYNOPSIS         top


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 -aay 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 to activate LVs that are not layered on top of
       encrypted devices.

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

       lvm2-activation-net.service is run after systemd's special 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).
