[ClusterLabs] Pacemaker shows false status of a resource and doesn't react on OCF_NOT_RUNNING rc.

[Kostiantyn Ponomarenko]

Just in case, this is the monitor function from the resource agent:
ra_monitor() {
#   ocf_log info "$RA: [monitor]"
    systemctl status ${service}
    rc=$?
    if [ "$rc" -eq "0" ]; then
        return $OCF_SUCCESS
    fi

    ocf_log warn "$RA: [monitor] : got rc=$rc"
    return $OCF_NOT_RUNNING
}

Thank you,
Kostia
