/etc/ha.d/ha.cf
#
# There are lots of options in this file. All you have to have is a set
# of nodes listed {"node ...} one of {serial, bcast, mcast, or ucast},
# and a value for "auto_failback".
#
# ATTENTION: As the configuration file is read line by line,
# THE ORDER OF DIRECTIVE MATTERS!
#
# In particular, make sure that the udpport, serial baud rate
# etc. are set before the heartbeat media are defined!
# debug and log file directives go into effect when they
# are encountered.
#
# All will be fine if you keep them ordered as in this example.
#
#
# Note on logging:
# If any of debugfile, logfile and logfacility are defined then they
# will be used. If debugfile and/or logfile are not defined and
# logfacility is defined then the respective logging and debug
# messages will be loged to syslog. If logfacility is not defined
# then debugfile and logfile will be used to log messges. If
# logfacility is not defined and debugfile and/or logfile are not
# defined then defaults will be used for debugfile and logfile as
# required and messages will be sent there.
#
# File to write debug messages to
debugfile /var/log/ha-debug
#
#
# File to write other messages to
#
logfile /var/log/ha-log
#
#
# Facility to use for syslog()/logger
#

#
#
# A note on specifying "how long" times below...
#
# The default time unit is seconds
# 10 means ten seconds
#
# You can also specify them in milliseconds
# 1500ms means 1.5 seconds
#
#
# keepalive: how long between heartbeats?
#
keepalive 2
#
# deadtime: how long-to-declare-host-dead?
#
# If you set this too low you will get the problematic
# split-brain (or cluster partition) problem.
# See the FAQ for how to use warntime to tune deadtime.
#
deadtime 10
#
# warntime: how long before issuing "late heartbeat" warning?
# See the FAQ for how to use warntime to tune deadtime.
#
warntime 10
#
#
# Very first dead time (initdead)
#
# On some machines/OSes, etc. the network takes a while to come up
# and start working right after you've been rebooted. As a result
# we have a separate dead time for when things first come up.
# It should be at least twice the normal dead time.
#
initdead 120

#
# What UDP port to use for bcast/ucast communication?
#

#
# [dev] device to send/rcv heartbeats on
# [mcast group] multicast group to join (class D multicast address
# 224.0.0.0 - 239.255.255.255)
# [port] udp port to sendto/rcvfrom (set this value to the
# same value as "udpport" above)
# [ttl] the ttl value for outbound heartbeats. this effects
# how far the multicast packet will propagate. (0-255)
# Must be greater than zero.
# [loop] toggles loopback for outbound multicast heartbeats.
# if enabled, an outbound packet will be looped back and
# received by the interface it was sent on. (0 or 1)
# Set this value to zero.
#
#
#mcast eth0 225.0.0.1 694 1 0

# Any of the following case-insensitive values will work for true:
# true, on, yes, y, 1
# Any of the following case-insensitive values will work for false:
# false, off, no, n, 0
#
#
#
# auto_failback: determines whether a resource will
# automatically fail back to its "primary" node, or remain
# on whatever node is serving it until that node fails, or
# an administrator intervenes.
#
# The possible values for auto_failback are:
# on - enable automatic failbacks
# off - disable automatic failbacks
# legacy - enable automatic failbacks in systems
# where all nodes do not yet support
# the auto_failback option.
#
# auto_failback "on" and "off" are backwards compatible with the old
# "nice_failback on" setting.
#
# See the FAQ for information on how to convert
# from "legacy" to "on" without a flash cut.
# (i.e., using a "rolling upgrade" process)
#
# The default value for auto_failback is "legacy", which
# will issue a warning at startup. So, make sure you put
# an auto_failback directive in your ha.cf file.
# (note: auto_failback can be any boolean or "legacy")
#
auto_failback on

#
# Basic STONITH support
# Using this directive assumes that there is one stonith
# device in the cluster. Parameters to this device are
# read from a configuration file. The format of this line is:
#
# stonith
#
# NOTE: it is up to you to maintain this file on each node in the
# cluster!
#
#stonith baytech /etc/ha.d/conf/stonith.baytech
#
# STONITH support
# You can configure multiple stonith devices using this directive.
# The format of the line is:
# stonith_host
#
# to or * to mean it is aclearcase/" target="_blank" >ccessible from any host.
#
# supported drives is in /usr/lib/stonith.)
#
# format for a particular device, run:
# stonith -l -t
#
#
# Note that if you put your stonith device access information in
# here, and you make this file publically readable, you're asking
# for a denial of service attack ;-)
#
# To get a list of supported stonith devices, run
# stonith -L
# For detailed information on which stonith devices are supported
# and their detailed configuration options, run this command:
# stonith -h
#
#stonith_host * baytech 10.0.0.3 mylogin mysecretpassword

#stonith_host kathy rps10 /dev/ttyS1 ken3 0
#
# Watchdog is the watchdog timer. If our own heart doesn't beat for
# a minute, then our machine will reboot.
# NOTE: If you are using the software watchdog, you very likely
# wish to load the module with the parameter "nowayout=0" or
# compile it without CONFIG_WATCHDOG_NOWAYOUT set. Otherwise even
# an orderly shutdown of heartbeat will trigger a reboot, which is
# very likely NOT what you want.

/etc/ha.d/haresources
#
# This is a list of resources that move from machine to machine as
# nodes go down and come up in the cluster. Do not include
# "administrative" or fixed IP addresses in this file.
#
#
# The haresources files MUST BE IDENTICAL on all nodes of the cluster.
#
# The node names listed in front of the resource group information
# is the name of the preferred node to run the service. It is
# not necessarily the name of the current machine. If you are running
# auto_failback ON (or legacy), then these services will be started
# up on the preferred nodes - any time they're up.
#
# If you are running with auto_failback OFF, then the node information
# will be used in the case of a simultaneous start-up, or when using
# the hb_standby command.
#
# BUT FOR ALL OF THESE CASES, the haresources files MUST BE IDENTICAL.
# If your files are different then almost certainly something
# won't work right.
#
#
#
# We refer to this file when we're coming up, and when a machine is being
# taken over after going down.
#
# You need to make this right for your installation, then install it in
# /etc/ha.d
#
# Each logical line in the file constitutes a "resource group".
# A resource group is a list of resources which move together from
# one node to another - in the order listed. It is assumed that there
# is no relationship between different resource groups. These
# resource in a resource group are started left-to-right, and stopped
# right-to-left. Long lists of resources can be continued from line
# to line by ending the lines with backslashes ("\").
#
# These resources in this file are either IP addresses, or the name
# of scripts to run to "start" or "stop" the given resource.
#
# The format is like this:
#
#node-name resource1 resource2 ... resourceN
#
#
# If the resource name contains an :: in the middle of it, the
# part after the :: is passed to the resource script as an argument.
# Multiple arguments are separated by the :: delimeter
#
# In the case of IP addresses, the resource script name IPaddr is
# implied.
#
# For example, the IP address 135.9.8.7 could also be represented
# as IPaddr::135.9.8.7
#
# THIS IS IMPORTANT!! vvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvv
#
# The given IP address is directed to an interface which has a route
# to the given address. This means you have to have a net route
# set up outside of the High-Availability structure. We don't set it
# up here -- we key off of it.
#
# The broadcast address for the IP alias that is created to support
# an IP address defaults to the highest address on the subnet.
#
# The netmask for the IP alias that is created defaults to the same
# netmask as the route that it selected in in the step above.
#
# The base interface for the IPalias that is created defaults to the
# same netmask as the route that it selected in in the step above.
#
# If you want to specify that this IP address is to be brought up
# on a subnet with a netmask of 255.255.255.0, you would specify
# this as IPaddr::135.9.8.7/24 .
#
# If you wished to tell it that the broadcast address for this subnet
# was 135.9.8.210, then you would specify that this way:
# IPaddr::135.9.8.7/24/135.9.8.210
#
# If you wished to tell it that the interface to add the address to
# is eth0, then you would need to specify it this way:
# IPaddr::135.9.8.7/24/eth0
#
# And this way to specify both the broadcast address and the
# interface:
# IPaddr::135.9.8.7/24/eth0/135.9.8.210
#
# The IP addresses you list in this file are called "service" addresses,
# since they're they're the publicly advertised addresses that clients
# use to get at highly available services.
#
# For a hot/standby (non load-sharing) 2-node system with only
# a single service address,
# you will probably only put one system name and one IP address in here.
# The name you give the address to is the name of the default "hot"
# system.
#
# Where the nodename is the name of the node which "normally" owns the
# resource. If this machine is up, it will always have the resource
# it is shown as owning.
#
# The string you put in for nodename must match the uname -n name
# of your machine. Depending on how you have it administered, it could
# be a short name or a FQDN.
