# 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.
# 这是当集群中的节点拓机和启动时从一台机器转移到另一台机器的resources列表，不要包含管理或已用IP地址在这个文件中。
#
#
<VERY IMPORTANT NOTE>
# The haresources files MUST BE IDENTICAL on all
nodes of the cluster.
# 此haresources文件在所有的集群节点中都必须相同
# 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.
# 列在resource组信息前的节点名称是优先运行服务的节点名称，它不需要是当前机器的名称，如果你运行auto_failback
on(或者
# legacy)，那么这些服务将会在优先节点启动，只要它们是运行的。
#
# 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 {foreign,local}
command.
# 如果你运行auto_failback off，那么节点信息将使用在同时启动的情况，或当使用hb_standby
{foreign,local}命令时。
#
# 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.
# 但是对于所有的这些情况，此haresources文件都必须相同。如果你的文件不同那么肯定有某些东西将不能正常工作。
#
</VERY IMPORTANT NOTE>
#
#
# We refer to this file when we're
coming up, and when a machine is being
# taken over after going
down.
# 我们在起动的时候和一个机器停机后被接管的时候参考这个文件。
#
# You need to make this right
for your installation, then install it
in
# /etc/ha.d
# 你必须让它符合你的安装，然后安装它到/etc/ha.d目录。
#
# 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
("\").
# 在文件里面的每个逻辑行组成一个“resource group”。一个resource
group就是从一个节点移动到另一个的resources的列表。
# 可以假设不同的resource groups之间是没有关系的。resource
group的resource启动时是从左到右的。关闭时是从右到左的。
# 长的resources列表可以以反斜杠（“\”）结尾来续行。
#
# These
resources in this file are either IP addresses, or the name
# of scripts to
run to "start" or "stop" the given resource.
# 在
这个文件里面的resources可以是IP地址，也可以是用于“start”或“stop”给定的resource的脚本名称
#
# 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
# 如果resource的名称包含一个::在它的中间，在::后面的部分会传递给resource的脚本中作为一个参数，多个参数会以::分割。
#
# In
the case of IP addresses, the resource script name IPaddr
is implied.
# 在IP地址的情况中，resource脚本名称IPaddr是隐含的。
#
# For example, the IP
address 135.9.8.7 could also be represented
# as
IPaddr::135.9.8.7
# 例如：IP地址135.9.8.7也可以被表现为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.
# 给定的IP地址会直接连到有路由到给定的地址的接口上，这也就意味着你必须要在 High-Availability
外部配置一个网络路由。我们不在这里配置，我们切断它。
#
# The broadcast address for the IP alias that
is created to support
# an IP address defaults to the highest address on the
subnet.
# IP别名的广播地址将被缺省创建为支持IP地址的子网里的最高地址
#
# 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.
# IP别名的子网掩码将被缺省创建为与上面选择的路由相同的子网掩码
#
# The base interface for the
IPalias that is created defaults to the
# same netmask as the route that it
selected in the step above.
# IP别名的基础接口将被缺省创建为与上面选择的路由相同的子网掩码
#
# 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 .
# 如果你想要指定某个IP地址用指定的子网掩码来启动，那么像这样指定它
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
# 如果你想要指明这个子网的广播地址为135.9.8.210，那么可以像这样指定
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
# 如果你希望指明要增加地址的接口是eth0，那么你需要像这样指定
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
# 同时指定广播地址和接口的方法为：
# 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 the publicly advertised addresses that clients
# use to get at highly
available
services.
# 列表在这个文件中的IP地址叫做服务地址，它们是客户端用于获取高可用服务的公共通告地址
#
# 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.
# 对于一个hot/standby（非共享负载）单服务地址的双节点系统，你可能只需要放置一个系统名称和一个IP地址在这里。你给定的地址对应的名字就是缺省的hot系统的名字。
#
# 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.
# 节点名称就是正常情况下拥有resource的节点的名称。如果此机器是up的，他将一直拥有以拥有显示的resource。
#
# 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.
# 设置作为节点名称的字符串必须匹配在机器上使用uname
-n获得的名字。基于你如果进行管理，它可能是一个缩写名称或一个FQDN。

# Simple
case: One service address, default subnet and netmask
# No servers that go
up and down with the IP
address
# 简单情况：一个服务地址，缺省子网和掩码，没有服务与IP地址一起启动和关闭
#
#just.linux-ha.org 135.9.216.110

#-------------------------------------------------------------------
#
# Assuming
the adminstrative addresses are on the same subnet...
# A little more complex
case: One service address, default subnet
# and netmask, and you want to
start and stop http when you get
# the IP
address...
# 假定管理地址在相同的子网...
# 稍微复杂一些的情况：一个服务地址，缺省子网和子网掩码，同时你要在获得IP地址的时候启动和停止http。
#
#just.linux-ha.org 135.9.216.110
http
#-------------------------------------------------------------------
#
# A
little more complex case: Three service addresses, default subnet
# and
netmask, and you want to start and stop http when you get
# the IP
address...
# 稍微复杂一些的情况：三个服务地址，缺省子网和掩码，同时你要在获得IP地址的时候启动和停止http。
#
#just.linux-ha.org 135.9.216.110
135.9.215.111 135.9.216.112

#-------------------------------------------------------------------
#
# One
service address, with the subnet, interface and bcast addr
# explicitly
defined.
# 一个服务地址，显式指定子网，接口，广播地址
#
#just.linux-ha.org 135.9.216.3/28/eth0/135.9.216.12

An example where a shared filesystem is to be used.
# Note that
multiple aguments are passed to this script using
# the delimiter '::'
to separate each
argument.
# 一个使用共享文件系统的例子
# 需要注意用'::'分隔的多个参数被传递到了这个脚本
#
#node1
10.0.0.170 Filesystem::/dev/sda1::/data1::ext2
#
# Regarding the
node-names in this file:
# 关于这个文件中的节点名称：
# They must match the names of
the nodes listed in ha.cf, which in turn
# must match the `uname -n` of some
node in the cluster. So they aren't
# virtual in any sense of the
word.
# 它们必须匹配在ha.cf中列出的节点名称，依次必须匹配集群中的某些节点'unmae -n'的结果。所以它们不是对于词的虚假感觉。
