Clustering and cronjobs

[Zu Zhihui (祖志辉)]

Assume your shared storage is mounted on /opt/data
Use the following script as your cron script.


mountpoint -q /opt/data
if [ $? -eq 0 ]; then
   echo "this is the active node"
   #execute some scripts.
else
   echo "this is not the active node, do nothing"
fi


Hope it help
