# Corosync itself works without a cluster name, but DLM needs one.
# The cluster name is also written into the VG metadata of newly
# created shared LVM volume groups, if lvmlockd uses DLM locking.
# It is also used for computing mcastaddr, unless overridden below.
cluster_name: debian
# How long before declaring a token lost (ms)
token: 3000
# How many token retransmits before forming a new configuration
token_retransmits_before_loss_const: 10
# Limit generated nodeids to 31-bits (positive signed integers)
clear_node_high_bit: yes
# crypto_cipher and crypto_hash: Used for mutual node authentication.
# If you choose to enable this, then do remember to create a shared
# secret with "corosync-keygen".
# enabling crypto_cipher, requires also enabling of crypto_hash.
# crypto_cipher and crypto_hash should be used instead of deprecated
# secauth parameter.
# Valid values for crypto_cipher are none (no encryption), aes256, aes192,
# aes128 and 3des. Enabling crypto_cipher, requires also enabling of
# crypto_hash.
crypto_cipher: none
# Valid values for crypto_hash are none (no authentication), md5, sha1,
# sha256, sha384 and sha512.
crypto_hash: none
# Optionally assign a fixed node id (integer)
# nodeid: 1234
# interface: define at least one interface to communicate
# over. If you define more than one interface stanza, you must
# also set rrp_mode.
interface {

ringnumber: 0
# This is normally the *network* address of the
# interface to bind to. This ensures that you can use
# identical instances of this configuration file
# across all your cluster nodes, without having to
# modify this option.
bindnetaddr: 127.0.0.1
# However, if you have multiple physical network
# interfaces configured for the same subnet, then the
# network address alone is not sufficient to identify
# the interface Corosync should bind to. In that case,
# configure the *host* address of the interface
# instead:
# bindnetaddr: 192.168.1.1
# When selecting a multicast address, consider RFC
# 2365 (which, among other things, specifies that
# 239.255.x.x addresses are left to the discretion of
# the network administrator). Do not reuse multicast
# addresses across multiple Corosync clusters sharing
# the same network.
# mcastaddr: 239.255.1.1
# Corosync uses the port you specify here for UDP
# messaging, and also the immediately preceding
# port. Thus if you set this to 5405, Corosync sends
# messages over UDP ports 5405 and 5404.
mcastport: 5405
