dmeventd --- Device-mapper event daemon


   dmeventd [-d [-d [-d]]] [-f] [-h] [-l] [-R] [-V] [-?]


   dmeventd  is  the  event  monitoring  daemon for device-mapper devices.
   Library plugins can register  and  carry  out  actions  triggered  when
   particular events occur.


          Attempts   to   handle   device   failure   automatically.   See

          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.

          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.


          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.

          Don't fork, run in the foreground.

          Show help information.

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

          Show help information on stderr.

          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.

          Show version of dmeventd.
