I find it hard to believe that even 1 rsync will not swamp your bandwidth as disk I/O should be WAY faster than the network.

If you want more speed try the -z (or --compress) rsync option and compress the data transfered.

Funny thing is I usually find that rsync swamps my network and even web service requests from/to the boxes concerned tend to timeout a lot. More often than not, I find myself using --bwlimit to slow things down!

ocf_heartbeat_rsyncd

OCF_HEARTBEAT_RSYNCD(7) 					OCF resource agents					   OCF_HEARTBEAT_RSYNCD(7)

NAME

       ocf_heartbeat_rsyncd - Manages an rsync daemon

SYNOPSIS

       rsyncd [start | stop | monitor | meta-data | validate-all]

DESCRIPTION

       This script manages rsync daemon

SUPPORTED PARAMETERS

       binpath
	   The rsync binary path. For example, "/usr/bin/rsync"

	   (optional, string, default "rsync")

       conffile
	   The rsync daemon configuration file name with full path. For example, "/etc/rsyncd.conf"

	   (optional, string, default "/etc/rsyncd.conf")

       bwlimit
	   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.

	   (optional, string, no default)

SUPPORTED ACTIONS

       This resource agent supports the following actions (operations):

       start
	   Starts the resource. Suggested minimum timeout: 20s.

       stop
	   Stops the resource. Suggested minimum timeout: 20s.

       monitor
	   Performs a detailed status check. Suggested minimum timeout: 20s. Suggested interval: 60s.

       validate-all
	   Performs a validation of the resource configuration. Suggested minimum timeout: 20s.

       meta-data
	   Retrieves resource agent metadata (internal use only). Suggested minimum timeout: 5s.

EXAMPLE

       The following is an example configuration for a rsyncd resource using the crm(8) shell:

	   primitive p_rsyncd ocf:heartbeat:rsyncd 
	     op monitor depth="0" timeout="20s" interval="60s"
