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.
