Or you could simply add the following to /etc/periodic.conf[.local]:

daily_status_gmirror_enable="YES"

If you use nagios (or compatible) net-mgmt/nagios-geom in ports works

I don't know any daemon like solution so I wrote some simple shell 
script. Its used on all our machines. It should be run be cron in some 
sane interval (like each 5 or 10 minutes)


#!/bin/sh

## $Id: check_gmirror.sh 8c1f418ba7f5 2017-06-15 12:36 +0200 lachman $

export PATH="/sbin:/bin:/usr/sbin:/usr/bin:/usr/local/sbin:/usr/local/bin"

mailto="y...@example.com"
subject_pref="$(hostname) gmirror"
notify_state="/var/run/${0##*/}.notified"

cmd_out=$(gmirror status -s)

components="$(echo "$cmd_out" | grep -F -v COMPLETE)"

if [ -n "$components" ]; then
if [ ! -f "$notify_state" ]; then
subject="$subject_pref FAILED - $(date '+%Y-%m-%d %H:%M:%S')"
echo "$cmd_out" | sed -E 's/(SYNCHRONIZING,) [0-9]+%/\1 x%/' > 
"$notify_state"

echo "$cmd_out" | mail -s "$subject" "$mailto"
echo "$subject" | logger
else
subject="$subject_pref FAILED - $(date '+%Y-%m-%d %H:%M:%S')"
echo "$cmd_out" | sed -E 's/(SYNCHRONIZING,) [0-9]+%/\1 x%/' > 
"$notify_state.now"
diff -u -b -B "$notify_state" "$notify_state.now" > 
"$notify_state.diff"


if [ -s "$notify_state.diff" ]; then## if diff is not empty
cat "$notify_state.diff" | mail -s "$subject" "$mailto"
echo "$subject additional failure occurred" | logger
cp "$notify_state.now" "$notify_state"
fi
rm "$notify_state.now" "$notify_state.diff"
fi
else
if [ -f "$notify_state" ]; then
rm "$notify_state"
subject="$subject_pref now OK - $(date '+%Y-%m-%d %H:%M:%S')"
echo "$cmd_out" | mail -s "$subject" "$mailto"
echo "$subject" | logger
fi
fi


We have similar script for checking ZFS too.

We use it in production. Works as designed.

Notification for GMirror failures

[Andrea Brancatelli]

Hi, 

out of curiosity, does any kind of GMirror-failure notification tools
exist? 

Either native... SNMP... external ports... whatever?
