DESCRIPTION

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

       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).

       Thin   Monitors how full a thin pool 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).
