# OCF Resource Agent compliant IPaddr2 script.

# Based on work by Tuomo Soini, ported to the OCF RA API by Lars
# Marowsky-Br馥. Implements Cluster Alias IP functionality too.

# TODO:
# - There ought to be an ocf_run_cmd function which does all logging,

# - Make this the standard IP address agent on Linux; the other

# the legacy heartbeat resource script...
# - Check LVS <-> clusterip incompatibilities.

<resource-agent name="IPaddr2">
<version>1.0</version>
<longdesc lang="en">
This Linux-specific resource manages IP alias IP addresses.
It can add an IP alias, or remove one.
In addition, it can implement Cluster Alias IP functionality
if invoked as a clone resource.
</longdesc>
<shortdesc lang="en">Manages virtual IPv4 addresses (Linux specific version)</shortdesc>
<parameters>
<parameter name="ip" unique="1" required="1">
<longdesc lang="en">
The IPv4 address to be configured in dotted quad notation, for example
"192.168.1.1".
</longdesc>
<shortdesc lang="en">IPv4 address</shortdesc>
<content type="string" default="" />
</parameter>
<parameter name="nic" unique="0">
<longdesc lang="en">
The base network interface on which the IP address will be brought
online.
If left empty, the script will try and determine this from the
routing table.
Do NOT specify an alias interface in the form eth0:1 or anything here;
rather, specify the base interface only.
Prerequisite:
There must be at least one static IP address, which is not managed by
the cluster, assigned to the network interface.
If you can not assign any static IP address on the interface,
modify this kernel parameter:
sysctl -w net.ipv4.conf.all.promote_secondaries=1
(or per device)
</longdesc>
<shortdesc lang="en">Network interface</shortdesc>
<content type="string" default="eth0"/>
</parameter>
<parameter name="cidr_netmask">
<longdesc lang="en">
The netmask for the interface in CIDR format
(e.g., 24 and not 255.255.255.0)
If unspecified, the script will also try to determine this from the
routing table.
</longdesc>
<shortdesc lang="en">CIDR netmask</shortdesc>
<content type="string" default=""/>
</parameter>
<parameter name="broadcast">
<longdesc lang="en">
Broadcast address associated with the IP. If left empty, the script will
determine this from the netmask.
</longdesc>
<shortdesc lang="en">Broadcast address</shortdesc>
<content type="string" default=""/>
</parameter>
<parameter name="iflabel">
<longdesc lang="en">
You can specify an additional label for your IP address here.
This label is appended to your interface name.
If a label is specified in nic name, this parameter has no effect.
</longdesc>
<shortdesc lang="en">Interface label</shortdesc>
<content type="string" default=""/>
</parameter>
<parameter name="lvs_support">
<longdesc lang="en">
Enable support for LVS Direct Routing configurations. In case a IP
address is stopped, only move it to the loopback device to allow the
local node to continue to service requests, but no longer advertise it
on the network.
</longdesc>
<shortdesc lang="en">Enable support for LVS DR</shortdesc>
<content type="boolean" default="false"/>
</parameter>
<parameter name="mac">
<longdesc lang="en">
Set the interface MAC address explicitly. Currently only used in case of
the Cluster IP Alias. Leave empty to chose automatically.
</longdesc>
<shortdesc lang="en">Cluster IP MAC address</shortdesc>
<content type="string" default=""/>
</parameter>
<parameter name="clusterip_hash">
<longdesc lang="en">
Specify the hashing algorithm used for the Cluster IP functionality.
</longdesc>
<shortdesc lang="en">Cluster IP hashing function</shortdesc>
<content type="string" default="sourceip-sourceport"/>

If true, add the clone ID to the supplied value of ip to create
a unique address to manage
</longdesc>
<shortdesc lang="en">Create a unique address for cloned instances</shortdesc>

<longdesc lang="en">
Number of unsolicited ARP packets to send.
</longdesc>
<shortdesc lang="en">ARP packet count</shortdesc>
<content type="integer" default="5"/>
</parameter>
<parameter name="arp_bg">
<longdesc lang="en">
Whether or not to send the arp packets in the background.
</longdesc>
<shortdesc lang="en">ARP from background</shortdesc>
<content type="string" default="yes"/>
</parameter>
<parameter name="arp_mac">
<longdesc lang="en">
MAC address to send the ARP packets too.
You really shouldn't be touching this.
</longdesc>
<shortdesc lang="en">ARP MAC</shortdesc>
<content type="string" default="ffffffffffff"/>
</parameter>
<parameter name="flush_routes">
<longdesc lang="en">
Flush the routing table on stop. This is for
applications which use the cluster IP address
and which run on the same physical host that the
IP address lives on. The Linux kernel may force that
application to take a shortcut to the local loopback
interface, instead of the interface the address
is really bound to. Under those circumstances, an
application may, somewhat unexpectedly, continue
to use connections for some time even after the
IP address is deconfigured. Set this parameter in
order to immediately disable said shortcut when the
IP address goes away.
