NAMEocf_heartbeat_IPaddr − Manages virtual IPv4 addresses (portable version)
SYNOPSISIPaddr [start | stop | monitor | meta−data | validate−all]
DESCRIPTIONThis script manages IP alias IP addresses It can add an IP alias, or remove one​.
SUPPORTED PARAMETERSip 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 ACTIONSThis 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 SHELLThe 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 PCSThe 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"
