# Resource script for PVFS2_notify
#
# Provides a generic hook for sending notifications if a PVFS2 resource is
# failed over to another node.
#
# Based on MailTo script by Alan Robertson <[e-mail]>
#
# Description: Logs a message whenever a resource group starts or stops.
#
#      OCF parameters are as below:
#               OCF_RESKEY_conf_dir
#               OCF_RESKEY_title
#               OCF_RESKEY_firsthost
