 One way is to search the group_tool output:

$ group_tool | grep "master node" | awk '{print $3 }'

Did you added status_file option in quorumd ? Try something like below.

<quorumd interval="1" tko="5" votes="2" log_level="7"
device="/dev/vg01/lv01" status_file="/var/log/qdisk-status.log">
   <heuristic program="ping -c2 -t2 -w1" score="1" interval="5"/>
