## Adding a notification resource 

To synchronize data between the master and backup nodes, notification resources can be added on both nodes as follows:

Save syncup.sh  in a directory of your choosing, but be sure to refer to the proper location in subsequent steps. In these examples, the script is saved in /root/syncup . Replace the value that is assigned to inotifyDir with the directory where the inotifywait  command resides on the master and backup nodes. The following command can be used to locate the directory: 

[root@dsm-master bin]# locate inotifywait
