lvmetad is a metadata caching daemon for LVM. The daemon receives notifications from udev rules (which must be installed for LVM to work correctly when lvmetad is in use). Through these notifications, lvmetad has an up-to-date and consistent image of the volume groups available in the system.
lvmetad is used by LVM only if it is enabled in (5) by specifying the global/use_lvmetad setting. If this is not defined in the LVM configuration explicitly then default setting is used instead (see the output of lvm dumpconfig --type default global/use_lvmetad command).
To run the daemon in a test environment both the pidfile_path and the socket_path should be changed from the defaults.
