DMEVENTD(8)                                                        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.
