NAME

       ocf_heartbeat_IPaddr - Manages virtual IPv4 addresses (portable version)

SYNOPSIS

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

DESCRIPTION

       This script manages IP alias IP addresses It can add an IP alias, or remove one.

SUPPORTED PARAMETERS

       ip
           The IPv4 address to be configured in dotted quad notation, for example "192.168.1.1".

           (unique, required, string, no default)

       nic
           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)

           (optional, string, default "eth0")

       cidr_netmask
           The netmask for the interface in CIDR format. (ie, 24), or in dotted quad notation
           255.255.255.0).

           If unspecified, the script will also try to determine this from the routing table.

           (optional, string, no default)

       broadcast
           Broadcast address associated with the IP. If left empty, the script will determine
           this from the netmask.

           (optional, string, no default)

       iflabel
           You can specify an additional label for your IP address here.

           (optional, string, no default)

       lvs_support
           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.

           (optional, boolean, default false)

       local_stop_script
           Script called when the IP is released

           (optional, string, no default)

       local_start_script
           Script called when the IP is added

           (optional, string, no default)

       ARP_INTERVAL_MS
           milliseconds between ARPs

           (optional, integer, default 500)

       ARP_REPEAT
           How many gratuitous ARPs to send out when bringing up a new address

           (optional, integer, default 10)

       ARP_BACKGROUND
           run in background (no longer any reason to do this)

           (optional, boolean, default yes)

       ARP_NETMASK
           netmask for ARP - in nonstandard hexadecimal format.

           (optional, string, default "ffffffffffff")

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:
           5s.

       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 CRM SHELL

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

           primitive p_IPaddr ocf:heartbeat:IPaddr \
             params \
               ip=string \
             op monitor depth="0" timeout="20s" interval="5s"

EXAMPLE PCS

       The following is an example configuration for a IPaddr resource using pcs(8)

           pcs resource create p_IPaddr ocf:heartbeat:IPaddr \
             ip=string \
             op monitor OCF_CHECK_LEVEL="0" timeout="20s" interval="5s"
