# Resource script for rsync daemon
#
# Description:  Manages rsync daemon as an OCF resource in 
#               an High Availability setup.

#
#	usage: $0 {start|stop|status|monitor|validate-all|meta-data}
#
#	The "start" arg starts rsyncd.
#
#	The "stop" arg stops it.
#
# OCF parameters:
# OCF_RESKEY_binpath
# OCF_RESKEY_conffile
# OCF_RESKEY_bwlimit
#
# Note:This RA requires that the rsyncd config files has a "pid file" 
# entry so that it is able to act on the correct process

This  option allows you to specify a maximum transfer 
rate in kilobytes per second.  This  option  is
most  effective  when  using rsync with large files
(several megabytes and up). Due to  the  nature  of
rsync  transfers,  blocks of data are sent, then if
rsync determines the transfer was too fast, it will
wait before sending the next data block. The result
is an average transfer rate equaling the  specified
limit. A value of zero specifies no limit.
