DMEVENTD(8)                          System Manager's Manual                          DMEVENTD(8)

NAME
       dmeventd — Device-mapper event daemon

SYNOPSIS
       dmeventd [-d [-d [-d]]] [-f] [-h] [-l] [-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).  Snapshot which runs out of space gets invalid  and  when
              it is mounted, it gets umounted if possible.

       Thin
              Monitors  how full a thin pool data and metadata 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).  If the thin-pool runs out of space,
              thin volumes are umounted if possible.

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.

       -l
              Log  through  stdout  and  stderr  instead  of syslog.  This option works only with
              option -f, otherwise it is ignored.

       -?
              Show help information on stderr.

       -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.
