Ok I got it :)
First thing, there is a bug in
/usr/lib/ocf/resource.d/heartbeat/ldirectord (package from the clusterlabs
redhat repo)
I have modified at line 51 and 52 like this:
$> vi /usr/lib/ocf/resource.d/heartbeat/ldirectord
from
LDIRCONF=${OCF_RESKEY_configfile:-/usr/sbin/ldirectord/ldirectord.cf}
LDIRECTORD=${OCF_RESKEY_ldirectord:-/etc/ldirectord}
to
LDIRCONF=${OCF_RESKEY_configfile:-/etc/ldirectord.cf}
LDIRECTORD=${OCF_RESKEY_ldirectord:-/usr/sbin/ldirectord}
I will store the ldirectord configfile at /etc, the binary is located at
/usr/sbin/ldirectord
After that modification I was able to add an virtual ip and the ldirectord
resource to pacemaker like this:
$> crm
crm(live)# configure
crm(live)configure# primitive ldirectord ocf:heartbeat:ldirectord \
> params configfile="/etc/ldirectord.cf" \
> op monitor interval="2m" timeout="20s" \
> op start timeout="90s" op stop timeout="100s"
crm(live)configure# primitive vip1 ocf:heartbeat:IPaddr2 \
> params lvs_support="true" ip="192.168.33.215" cidr_netmask="24"
broadcast="192.168.33.255" \
> op monitor interval="2m" timeout="20s" \
> op start timeout="90s" op stop timeout="100s"
crm(live)configure# save
crm(live)configure# verify
crm(live)configure# end
crm(live)# status

I have add no-quorum-policy="ignore" stonith-enabled="false" because at
the moment I have only 1 node (have some multicast problems on cisco
switch) and I don't configure the stonith option. Of course ldirectord
should be installed.
