# Configuration option global/event_activation.
# Activate LVs based on system-generated device events.
- # When a device appears on the system, a system-generated event runs
- # the pvscan command to activate LVs if the new PV completes the VG.
- # When event_activation is disabled, the system will generally run
- # a direct activation command to activate LVs in complete VGs.
- # Activation commands that are run by the system, either from events
- # or at fixed points during startup, use autoactivation (-aay). See
- # the --setautoactivation option or the auto_activation_volume_list
+ # When a PV appears on the system, a system-generated uevent triggers
+ # the lvm2-pvscan service which runs the pvscan --cache -aay command.
+ # If the new PV completes a VG, pvscan autoactivates LVs in the VG.
+ # When event_activation is disabled, the lvm2-activation services are
+ # generated and run at fixed points during system startup. These
+ # services run vgchange -aay to autoactivate LVs in VGs that happen
+ # to be present at that point in time.
+ # See the --setautoactivation option or the auto_activation_volume_list
# setting to configure autoactivation for specific VGs or LVs.
# This configuration option has an automatic default value.
