Here is a corresponding stupid script, called via cron:

>>>>>>>>>>
#!/bin/sh

LOG="/tmp/check_home_vols.log"
VOS="/usr/afs/bin/vos"
rm -f $LOG
touch $LOG
warncapacity="90"

$VOS listvldb -quiet -noauth | grep home | while read vol
do
  vosexa=`$VOS exa $vol -loc`
  maxquota=`echo $vosexa | awk -F " " '{print $16}'`
  used=`echo $vosexa | awk -F " " '{print $4}'`
  if [ "$maxquota" != "0" ]; then
    capacity=`echo $used/$maxquota*100 | bc -l | awk '{printf("%2.2lf\n", $1)}'`
    capacityint=`echo $capacity | cut -d. -f1`
    [ "$capacityint" -ge "$warncapacity" ] && echo $vol: $capacity >> $LOG
# else
#   user=`echo $vol | awk -F "." '{print $2}'`
#   echo "$user has unlimited quota."
  fi
done

cat $LOG
rm -f $LOG
