NAME

6       dmeventd — Device-mapper event daemon
7

SYNOPSIS

9       dmeventd [-d [-d [-d]]] [-f] [-h] [-l] [-R] [-V] [-?]
10

DESCRIPTION

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

LVM PLUGINS

17       Mirror
18              Attempts   to   handle   device   failure   automatically.   See
19              lvm.conf(5).
20
21       Raid
22              Attempts   to   handle   device   failure   automatically.   See
23              lvm.conf(5).
24
25       Snapshot
26              Monitors  how full a snapshot is becoming and emits a warning to
27              syslog when it exceeds 80% full.  The warning is  repeated  when
28              85%,  90%  and  95% of the snapshot is filled.  See lvm.conf(5).
29              Snapshot which runs out of space gets invalid  and  when  it  is
30              mounted, it gets umounted if possible.
31
32       Thin
33              Monitors  how full a thin pool data and metadata is becoming and
34              emits a warning to syslog when it exceeds 80% full.  The warning
35              is  repeated  when  85%, 90% and 95% of the thin pool is filled.
36              See lvm.conf(5).  If the thin-pool runs out of space, thin  vol‐
37              umes are umounted if possible.

OPTIONS

40       -d
41              Repeat  from  1  to  3  times  ( -d, -dd, -ddd ) to increase the
42              detail of debug messages sent to syslog.  Each extra d adds more
43              debugging information.
44
45       -f
46              Don't fork, run in the foreground.
47
48       -h
49              Show help information.
50
51       -l
52              Log  through  stdout  and stderr instead of syslog.  This option
53              works only with option -f, otherwise it is ignored.
54
55       -?
56              Show help information on stderr.
57
58       -R
59              Replace a running dmeventd instance. The running  dmeventd  must
60              be  version  2.02.77  or  newer.  The new dmeventd instance will
61              obtain a list of devices and events to  monitor  from  the  cur‐
62              rently running daemon.
63
64       -V
65              Show version of dmeventd.
