lvmpolld — LVM poll daemon

lvmpolld [--dump]
lvmpolld is polling daemon for LVM. The daemon receives requests for polling of already initialised operations originating in LVM2 command line tool. The requests for polling originate in the lvconvert, pvmove, lvchange or vgchange LVM2 commands.
The purpose of lvmpolld is to reduce the number of spawned background processes per otherwise unique polling operation. There should be only one. It also eliminates the possibility of unsolicited termination of background process by external factors.
lvmpolld is used by LVM only if it is enabled in lvm.conf(5) by specifying the global/use_lvmpolld setting. If this is not defined in the LVM configuration explicitly then default setting is used instead (see the output of lvmconfig --type default global/use_lvmpolld command).
To run the daemon in a test environment both the pidfile_path and the socket_path should be changed from the defaults.
