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.
