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 particular 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 currently running daemon.

       -V     Show version of dmeventd.
