Thank you for all your help it's much appreciated.
I have one more problem, I'm running apcupsd to monitor for power failures
so that the system can shutdown cleanly. When I start the apcupsd daemon and
stonith -t apcsmart -p "/dev/ttyS0 beta" -S
it returns with the following error:
CRITICAL **: APC_open_serialport: Could not lock tty /dev/ttyS0 (rc: -1)
If I stop apcupsd then it all works ok.
