You can add it as attribute to load balanced IP address resource to
your cib.xml file either manually or using GUI client. Something
like:
<nvpair id="lb_ip_lvs_support" name="lvs_support" value="true"/>

There are few more issues in that script in LVS-related part. Some
quoting issues. I've created IPaddr_lvs to address those issues which
seems to work for me. My patch, if you find it useful:

Looks like you have to set lvs_support to either "true" or "on", not
"1" in your heartbeat config.
However, this report should probably be sent (or cc-ed) to hearbeat
mailing list.
Btw: Have you configured ldirectord as OCF or LSB resource? I've had
issues with using it as OCF and had to switch type to LSB.
