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 par- ticular 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 vol- umes 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 Dont 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 cur- rently running daemon.
-V Show version of dmeventd.
