mosquitto and ram log files tmpfs on a raspberry

[alex jennings]

I have been struggling with sd card reliability on my openhab based set up. So I have been trying to reduce write loads by moving log files to RAM.

Everything works fine except I can only seem to get location notfications in mosquito from owntracks. Region events and waypoints just don't come through when I try and follow.

I have added this to /etc/fstab

tmpfs   /var/log                tmpfs   size=20M,defaults,noatime,mode=0755 0 0
tmpfs   /var/cache/apt/archives tmpfs   size=100M,defaults,noexec,nosuid,nodev,mode=0755 0 0
tmpfs   /var/spool/cups         tmpfs   size=100M,defaults,noatime,mode=0755 0 0
tmpfs   /var/spool/cups/tmp     tmpfs   defaults,noatime,mode=0755 0 0

I created a new file and set it to run at boot etc/init.d/prepare-dirs

Enter code here...#!/bin/bash
#

case "${1:-''}" in
  start)
        typeset -i i=0 max=${#DIR[*]}
        while (( i < max ))
        do
                mkdir  ${DIR[$i]}
                chmod 755 ${DIR[$i]}
                i=i+1
        done
        # set rights
        chown www-data.www-data ${DIR[0]}
    ;;
  stop)
    ;;

   ;;
  reload|force-reload)
   ;;
  status)
   ;;
  *)
   echo "Usage: $SELF start"
   exit 1
   ;;
esac

and to begin with I was getting nothing at all but adding this to the start section of /etc/init.d/mosquitto

mkdir /var/log/mosquitto
mkdir /var/log/mosquitto.log

this is my mosquito.conf

  GNU nano 2.2.6                          File: /etc/mosquitto/mosquitto.conf                                                           

# Place your local configuration in /etc/mosquitto/conf.d/

pid_file /var/run/mosquitto.pid

log_dest file /var/log/mosquitto/mosquitto.log

any suggestions would be gratefully received
