LVM2-ACTIVATION-GENERATOR(8) LVM2-ACTIVATION-GENERATOR(8)
lvm2-activation-generator - generator for systemd units to
activate LVM volumes on boot
/usr/lib/systemd/system-generators/lvm2-activation-generator
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
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).
