 Work around is to ensure that filesystems on wedges are 
 explicitly unmounted.
 
 So something like the following in /etc/rc.shutdown.local:
 
 fs=`mount | awk '{if ($1 ~ "^/dev/dk[0-9]") print $3}'`
 for f in $fs
 do
        echo "Unmounting $fs"
        umount $fs
 done
 
 There may be processes with open files on the filesystem which will stop 
 it being unmounted. You may want to add # KEYWORD: shutdown to relevant 
 rc.d scripts
 
 In my case, this is only likely to be samba and istgt, 
 so I stop those in the rc.shutdown.local script:
 
 fs=`mount | awk '{if ($1 ~ "^/dev/dk[0-9]") print $3}'`
 if [ -n "$fs" ]; then
          for srv in smbd istgt
          do
                  /etc/rc.d/$srv status > /dev/null
                  if [ $? = 0 ]; then
                          /etc/rc.d/$srv stop
                  fi
          done
 
          for f in $fs
          do
                  echo "Unmounting $fs"
                  umount $fs
          done
 fi
