If you have a TimeMachine on a NAS oder Linux Server, sometimes it tells you that the sparsbundle is already in use. This small script cleans up old AFP connections that are already dead. Change the PROCOWNER to the afpd root process owner.

afpd_cleanup.sh

#!/bin/bash

PROCOWNER=admin

for PID in $(ps waux | grep afpd | grep -v $PROCOWNER | awk '{print $1}')
do
  echo "==> checking pid $PID";
  lsof -i | grep afp | grep -v $PROCOWNER | awk '{print $2}' | grep $PID > /dev/null
  if [ $? -ne 0 ];
  then
    ps waux | grep $PID | grep -v $PROCOWNER
    #lsof | grep $PID | grep afpd | grep MD0_DATA
    echo -n "! already dead. killing $PID ... "
    kill $PID
    PID=''
    echo "done."
  else
    echo "still alive."
  fi
  echo ""
done
