lvmetad is usually combined with event-based system services that
automatically run pvscan --cache on disks added or removed.  This
way, the cache is automatically updated with metadata from new disks
when they appear.  LVM udev rules and systemd services implement this
automation.  Automatic scanning is usually combined with automatic
activation.  For more information, see pvscan(8).
