NAME
       dmeventd -- Device-mapper event daemon

SYNOPSIS
       dmeventd [-d [-d [-d]]] [-f] [-h] [-R] [-V] [-?]

DESCRIPTION
       dmeventd  is  the  event  monitoring  daemon for device-mapper devices.
       Library plugins can register and carry out actions triggered when  par-
       ticular events occur.

LVM PLUGINS
       Mirror Attempts   to   handle   device   failure   automatically.   See
              lvm.conf(5).

       Raid   Attempts  to   handle   device   failure   automatically.    See
              lvm.conf(5).

       Snapshot
              Monitors  how full a snapshot is becoming and emits a warning to
              syslog when it exceeds 80% full.  The warning is  repeated  when
              85%, 90% and 95% of the snapshot is filled.  See lvm.conf(5).

       Thin   Monitors how full a thin pool is becoming and emits a warning to
              syslog when it exceeds 80% full.  The warning is  repeated  when
              85%, 90% and 95% of the thin pool is filled.  See lvm.conf(5).

OPTIONS
       -d     Repeat  from  1  to  3  times  ( -d, -dd, -ddd ) to increase the
              detail of debug messages sent to syslog.  Each extra d adds more
              debugging information.

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

       -h, -? Show help information.

       -R     Replace  a  running dmeventd instance. The running dmeventd must
              be version 2.02.77 or newer.  The  new  dmeventd  instance  will
              obtain  a  list  of  devices and events to monitor from the cur-
              rently running daemon.

       -V     Show version of dmeventd.
