NAME dmeventd Device-mapper event daemon

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

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).

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.
