       lvmpolld — LVM poll daemon


       lvmpolld   [-l|--log   {all|wire|debug}]   [-p|--pidfile  pidfile_path]
       [-s|--socket socket_path] [-B|--binary  lvm_binary_path]  [-t|--timeout
       timeout_value] [-f|--foreground] [-h|--help] [-V|--version]

       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


       To  run  the daemon in a test environment both the pidfile_path and the
       socket_path should be changed from the defaults.

       -f, --foreground
              Don't fork, but run in the foreground.

       -h, --help
              Show help information.

       -l, --log {all|wire|debug}
              Select the type of  log  messages  to  generate.   Messages  are
              logged  by syslog.  Additionally, when -f is given they are also
              sent to standard error.  There are two classes of messages: wire
              and  debug. Selecting 'all' supplies both and is equivalent to a
              comma-separated list -l wire,debug.

       -p, --pidfile pidfile_path
              Path to the pidfile. This overrides both  the  built-in  default
              (/run/     and     the     environment     variable
              LVM_LVMPOLLD_PIDFILE.  This file is used to  prevent  more  than
              one instance of the daemon running simultaneously.

       -s, --socket socket_path
              Path  to  the  socket  file.  This  overrides  both the built-in
              default (/run/lvm/lvmpolld.socket) and the environment  variable

       -t, --timeout timeout_value
              The  daemon may shutdown after being idle for the given time (in
              seconds). When the option is omitted or the value given is  zero
              the daemon never shutdowns on idle.

       -B, --binary lvm_binary_path
              Optional  path  to  alternative LVM binary (default: /sbin/lvm).
              Use for testing purposes only.

       -V, --version
              Display the version of lvmpolld daemon.

       --dump Contact the running lvmpolld daemon to obtain the complete state
              and print it out in a raw format.


              Path for the pid file.

              Path for the socket file.


       lvm(8), lvm.conf(5)
